User interaction is not needed for exploitation.Product:
    AndroidVersions: Android kernelAndroid ID: A-216481035References: Upstream kernel (CVE-2022-20008)

  - Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation,     aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to     influence mispredicted branches. Then, cache allocation can allow the attacker to obtain sensitive     information. (CVE-2022-23960)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

An update of the linux package has been released.

The version of kernel installed on the remote host is prior to 5.15.43-20.103. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2023-023 advisory.

    2024-03-13: CVE-2022-48619 was added to this advisory.

    2023-10-12: CVE-2021-3923 was added to this advisory.

    2023-08-31: CVE-2023-4459 was added to this advisory.

    2023-08-31: CVE-2023-1637 was added to this advisory.

    2023-08-31: CVE-2023-4387 was added to this advisory.

    An issue was discovered in fs/io_uring.c in the Linux kernel through 5.11.8. It allows attackers to cause     a denial of service (deadlock) because exit may be waiting to park a SQPOLL thread, but concurrently that     SQPOLL thread is waiting for a signal to start, aka CID-3ebba796fa25. (CVE-2021-28951)

    A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a     privileged local account can leak kernel stack information when issuing commands to the     /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it     can be further used to defeat existing kernel protection mechanisms. (CVE-2021-3923)

    A flaw was found in unrestricted eBPF usage by the BPF_BTF_LOAD, leading to a possible out-of-bounds     memory write in the Linux kernel's BPF subsystem due to the way a user loads BTF. This flaw allows a local     user to crash or escalate their privileges on the system. (CVE-2022-0500)

    A flaw was found in the Linux kernel in linux/net/netfilter/nf_tables_api.c of the netfilter subsystem.
    This flaw allows a local user to cause an out-of-bounds write issue. (CVE-2022-1015)

    A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a     use-after-free. This issue needs to handle return with proper preconditions, as it can lead to a kernel     information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)

    When the KVM updates the guest's page table entry, it will first use get_user_pages_fast() to pin the     page, and when it fails (e.g. the vma->flags has VM_IO or VM_PFNMAP), it will get corresponding VMA where     the page lies in through find_vma_intersection(), calculate the physical address, and map the page to the     kernel virtual address through memremap(), and finally, write the update.The problem is that when we get     the vma through find_vma_intersection(), only VM_PFNMAP is checked, not both VM_IO and VM_PFNMAP. In the     reproducer below, after the KVM_SET_USER_MEMORY_REGION is completed, we replace the guest's memory mapping     with the kernel-user shared region of io_uring and then perform the KVM_TRANSLATE operation, which finally     triggers the page table entry update. Now, memremap() will return page_offset_base (direct mapping of all     physical memory) + vaddr (the linear address of KVM_TRANSLATE) + vm_pgoff (the offset when io_uring     performs mmap(2)), and use the return value as the base address for CMPXCHG (write 0x21 in this case).
    Since both vaddr and vm_pgoff are controllable by the user-mode process, writing may exceed the previously     mapped guest memory space and trigger exceptions such as UAF. The vulnerability shares similarities with     CVE-2021-22543. (CVE-2022-1158)

    A NULL pointer dereference issue was found in KVM when releasing a vCPU with dirty ring support enabled.
    This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a     kernel oops condition that results in a denial of service. (CVE-2022-1263)

    A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This     flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a     leak of internal kernel information. (CVE-2022-1353)

    perf: Fix sys_perf_event_open() race against self (CVE-2022-1729)

    A flaw was found in the Linux kernel's adjust_ptr_min_max_vals in the kernel/bpf/verifier.c function. In     this flaw, a missing sanity check for *_OR_NULL pointer types that perform pointer arithmetic may cause a     kernel information leak issue. (CVE-2022-23222)

    An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of     actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()     function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This     flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2639)

    The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets     are in the intended state. (CVE-2022-28893)

    Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to     cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14     and later versions. (CVE-2022-29581)

    A use-after-free flaw was found in the Linux kernel's io_uring interface subsystem in the way a user     triggers a race condition between timeout flush and removal. This flaw allows a local user to crash or     escalate their privileges on the system. (CVE-2022-29582)

    The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers     to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. (CVE-2022-30594)

    An issue was discovered in drivers/input/input.c in the Linux kernel before 5.17.10. An attacker can cause     a denial of service (panic) because input_set_capability mishandles the situation in which an event code     falls outside of a bitmap. (CVE-2022-48619)

    A flaw that boot CPU could be vulnerable for the speculative execution behavior kind of attacks in the     Linux kernel X86 CPU Power management options functionality was found in the way user resuming CPU from     suspend-to-RAM. A local user could use this flaw to potentially get unauthorized access to some memory of     the CPU similar to the speculative execution behavior kind of attacks. (CVE-2023-1637)

    A use-after-free flaw was found in vhost_net_set_backend in drivers/vhost/net.c in virtio network     subcomponent in the Linux kernel due to a double fget. This flaw could allow a local attacker to crash the     system, and could even lead to a kernel information leak problem. (CVE-2023-1838)

    Improper restriction of operations within the bounds of a memory buffer in some Intel(R) i915 Graphics     drivers for linux before kernel version 6.2.10 may allow an authenticated user to potentially enable     escalation of privilege via local access. (CVE-2023-28410)

    A use-after-free flaw was found in vmxnet3_rq_alloc_rx_buf in drivers/net/vmxnet3/vmxnet3_drv.c in     VMware's vmxnet3 ethernet NIC driver in the Linux Kernel. This issue could allow a local attacker to crash     the system due to a double-free while cleaning up vmxnet3_rq_cleanup_all, which could also lead to a     kernel information leak problem. (CVE-2023-4387)

    A NULL pointer dereference flaw was found in vmxnet3_rq_cleanup in drivers/net/vmxnet3/vmxnet3_drv.c in     the networking sub-component in vmxnet3 in the Linux Kernel. This issue may allow a local attacker with     normal user privilege to cause a denial of service due to a missing sanity check during cleanup.

The version of kernel installed on the remote host is prior to 5.10.112-108.499. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2023-036 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    ubi: Fix race condition between ctrl_cdev_ioctl and ubi_cdev_ioctl (CVE-2021-47634)

    In the Linux kernel, the following vulnerability has been resolved:

    Revert Revert block, bfq: honor already-setup queue merges (CVE-2021-47646)

    In the Linux kernel, the following vulnerability has been resolved:

    ASoC: soc-compress: prevent the potentially use of null pointer (CVE-2021-47650)

    A denial of service (DOS) issue was found in the Linux kernel's smb2_ioctl_query_info function in     the fs/cifs/smb2ops.c Common Internet File System (CIFS) due to an incorrect return from the memdup_user     function. This flaw allows a local, privileged (CAP_SYS_ADMIN) attacker to crash the system.
    (CVE-2022-0168)

    When the KVM updates the guest's page table entry, it will first use get_user_pages_fast() to pin the     page, and when it fails (e.g. the vma->flags has VM_IO or VM_PFNMAP), it will get corresponding VMA where     the page lies in through find_vma_intersection(), calculate the physical address, and map the page to the     kernel virtual address through memremap(), and finally, write the update.The problem is that when we get     the vma through find_vma_intersection(), only VM_PFNMAP is checked, not both VM_IO and VM_PFNMAP. In the     reproducer below, after the KVM_SET_USER_MEMORY_REGION is completed, we replace the guest's memory mapping     with the kernel-user shared region of io_uring and then perform the KVM_TRANSLATE operation, which finally     triggers the page table entry update. Now, memremap() will return page_offset_base (direct mapping of all     physical memory) + vaddr (the linear address of KVM_TRANSLATE) + vm_pgoff (the offset when io_uring     performs mmap(2)), and use the return value as the base address for CMPXCHG (write 0x21 in this case).
    Since both vaddr and vm_pgoff are controllable by the user-mode process, writing may exceed the previously     mapped guest memory space and trigger exceptions such as UAF. The vulnerability shares similarities with     CVE-2021-22543. (CVE-2022-1158)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of kernel-generic installed on the remote host is prior to 5.15.38 / 5.15.38_smp. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2022-129-01 advisory.

  - Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may     allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0001)

  - Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an     authorized user to potentially enable information disclosure via local access. (CVE-2022-0002)

  - A kernel information leak flaw was identified in the scsi_ioctl function in drivers/scsi/scsi_ioctl.c in     the Linux kernel. This flaw allows a local attacker with a special user privilege (CAP_SYS_ADMIN or     CAP_SYS_RAWIO) to create issues with confidentiality. (CVE-2022-0494)

  - A flaw was found in unrestricted eBPF usage by the BPF_BTF_LOAD, leading to a possible out-of-bounds     memory write in the Linux kernel's BPF subsystem due to the way a user loads BTF. This flaw allows a local     user to crash or escalate their privileges on the system. (CVE-2022-0500)

  - Memory leak in icmp6 implementation in Linux Kernel 5.13+ allows a remote attacker to DoS a host by making     it go out-of-memory via icmp6 packets of type 130 or 131. We recommend upgrading past commit     2d3916f3189172d5c69d33065c3c21119fe539fc. (CVE-2022-0742)

  - A memory leak flaw was found in the Linux kernel's DMA subsystem, in the way a user calls DMA_FROM_DEVICE.
    This flaw allows a local user to read random memory from the kernel space. (CVE-2022-0854)

  - An out-of-bounds (OOB) memory write flaw was found in the Linux kernel's watch_queue event notification     subsystem. This flaw can overwrite parts of the kernel state, potentially allowing a local user to gain     privileged access or cause a denial of service on the system. (CVE-2022-0995)

  - A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().
    This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in     privilege escalation. (CVE-2022-1011)

  - A flaw was found in the Linux kernel in linux/net/netfilter/nf_tables_api.c of the netfilter subsystem.
    This flaw allows a local user to cause an out-of-bounds write issue. (CVE-2022-1015)

  - A use-after-free flaw was found in the Linux kernel's sound subsystem in the way a user triggers     concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM     for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the     system. (CVE-2022-1048)

  - A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This     flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a     leak of internal kernel information. (CVE-2022-1353)

  - A NULL pointer dereference flaw was found in the Linux kernel's X.25 set of standardized network protocols     functionality in the way a user terminates their session using a simulated Ethernet card and continued     usage of this connection. This flaw allows a local user to crash the system. (CVE-2022-1516)

  - Linux PV device frontends vulnerable to attacks by backends T[his CNA information record relates to     multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Several Linux PV     device frontends are using the grant table interfaces for removing access rights of the backends in ways     being subject to race conditions, resulting in potential data leaks, data corruption by malicious     backends, and denial of service triggered by malicious backends: blkfront, netfront, scsifront and the     gntalloc driver are testing whether a grant reference is still in use. If this is not the case, they     assume that a following removal of the granted access will always succeed, which is not true in case the     backend has mapped the granted page between those two operations. As a result the backend can keep access     to the memory page of the guest no matter how the page will be used after the frontend I/O has finished.
    The xenbus driver has a similar problem, as it doesn't check the success of removing the granted access of     a shared ring buffer. blkfront: CVE-2022-23036 netfront: CVE-2022-23037 scsifront: CVE-2022-23038     gntalloc: CVE-2022-23039 xenbus: CVE-2022-23040 blkfront, netfront, scsifront, usbfront, dmabuf, xenbus,     9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no     longer in use, but the freeing of the related data page is not synchronized with dropping the granted     access. As a result the backend can keep access to the memory page even after it has been freed and then     re-used for a different purpose. CVE-2022-23041 netfront will fail a BUG_ON() assertion if it fails to     revoke access in the rx path. This will result in a Denial of Service (DoS) situation of the guest which     can be triggered by the backend. CVE-2022-23042 (CVE-2022-23036, CVE-2022-23037, CVE-2022-23038,     CVE-2022-23039, CVE-2022-23040, CVE-2022-23041, CVE-2022-23042)

  - kernel/bpf/verifier.c in the Linux kernel through 5.15.14 allows local users to gain privileges because of     the availability of pointer arithmetic via certain *_OR_NULL pointer types. (CVE-2022-23222)

  - Certain Arm Cortex and Neoverse processors through 2022-03-08 do not properly restrict cache speculation,     aka Spectre-BHB. An attacker can leverage the shared branch history in the Branch History Buffer (BHB) to     influence mispredicted branches. Then, cache allocation can allow the attacker to obtain sensitive     information. (CVE-2022-23960)

  - drivers/usb/gadget/legacy/inode.c in the Linux kernel through 5.16.8 mishandles dev->buf release.
    (CVE-2022-24958)

  - st21nfca_connectivity_event_received in drivers/nfc/st21nfca/se.c in the Linux kernel through 5.16.12 has     EVT_TRANSACTION buffer overflows because of untrusted length parameters. (CVE-2022-26490)

  - A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and     net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap     objects and may cause a local privilege escalation threat. (CVE-2022-27666)

  - In the Linux kernel before 5.17.1, a refcount leak bug was found in net/llc/af_llc.c. (CVE-2022-28356)

  - usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c in the Linux kernel through 5.17.1 has a double     free. (CVE-2022-28388)

  - mcba_usb_start_xmit in drivers/net/can/usb/mcba_usb.c in the Linux kernel through 5.17.1 has a double     free. (CVE-2022-28389)

  - ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free.
    (CVE-2022-28390)

  - In the Linux kernel before 5.17.3, fs/io_uring.c has a use-after-free due to a race condition in io_uring     timeouts. This can be triggered by a local user who has no access to any user namespace; however, the race     condition perhaps can only be exploited infrequently. (CVE-2022-29582)
