    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service, or information     leak.

    CVE-2022-2196

        A regression was discovered the KVM implementation for Intel CPUs,         affecting Spectre v2 mitigation for nested virtualisation.  When         KVM was used as the L0 hypervisor, an L2 guest could exploit this         to leak sensitive information from its L1 hypervisor.

    CVE-2022-3424

        Zheng Wang and Zhuorao Yang reported a flaw in the SGI GRU driver         which could lead to a use-after-free.  On systems where this driver         is used, a local user can explit this for denial of service (crash         or memory corruption) or possibly for privilege escalation.

        This driver is not enabled in Debian's official kernel         configurations.

    CVE-2022-3707

        Zheng Wang reported a flaw in the i915 graphics driver's         virtualisation (GVT-g) support that could lead to a double-free.
        On systems where this feature is used, a guest can exploit this         for denial of service (crash or memory corruption) or possibly for         privilege escalation.

    CVE-2022-4129

        Haowei Yan reported a race condition in the L2TP protocol         implementation which could lead to a null pointer dereference.  A         local user could exploit this for denial of service (crash).

    CVE-2022-4379

        Xingyuan Mo reported a flaw in the NFSv4.2 inter server to         server copy implementation which could lead to a use-after-free.

        This feature is not enabled in Debian's official kernel         configurations.

    CVE-2023-0045

        Rodrigo Branco and Rafael Correa De Ysasi reported that when a         user-space task told the kernel to enable Spectre v2 mitigation         for it, the mitigation was not enabled until the task was next         rescheduled.  This might be exploitable by a local or remote         attacker to leak sensitive information from such an application.

    CVE-2023-0458

        Jordy Zimmer and Alexandra Sandulescu found that getrlimit() and         related system calls were vulnerable to speculative execution         attacks such as Spectre v1.  A local user could explot this to         leak sensitive information from the kernel.

    CVE-2023-0459

        Jordy Zimmer and Alexandra Sandulescu found a regression in         Spectre v1 mitigation in the user-copy functions for the amd64         (64-bit PC) architecture.  Where the CPUs do not implement SMAP or         it is disabled, a local user could exploit this to leak sensitive         information from the kernel.  Other architectures may also be         affected.

    CVE-2023-0461

        slipper reported a flaw in the kernel's support for ULPs (Upper         Layer Protocols) on top of TCP that can lead to a double-free when         using kernel TLS sockets.  A local user can exploit this for         denial of service (crash or memory corruption) or possibly for         privilege escalation.

        Kernel TLS is not enabled in Debian's official kernel         configurations.

    CVE-2023-1073

        Pietro Borrello reported a type confusion flaw in the HID (Human         Interface Device) subsystem.  An attacker able to insert and         remove USB devices might be able to use this to cause a denial of         service (crash or memory corruption) or possibly to run arbitrary         code in the kernel.

    CVE-2023-1074

        Pietro Borrello reported a type confusion flaw in the SCTP         protocol implementation which can lead to a memory leak.  A local         user could exploit this to cause a denial of service (resource         exhaustion).

    CVE-2023-1076

        Pietro Borrello reported a type confusion flaw in the TUN/TAP         network driver, which results in all TUN/TAP sockets being marked         as belonging to user ID 0 (root).  This may allow local users to         evade local firewall rules based on user ID.

    CVE-2023-1077

        Pietro Borrello reported a type confusion flaw in the task         scheduler.  A local user might be able to exploit this to cause a         denial of service (crash or memory corruption) or possibly for         privilege escalation.

    CVE-2023-1078

        Pietro Borrello reported a type confusion flaw in the RDS protocol         implementation.  A local user could exploit this to cause a denial         of service (crash or memory corruption) or possibly for privilege         escalation.

    CVE-2023-1079

        Pietro Borrello reported a race condition in the hid-asus HID         driver which could lead to a use-after-free.  An attacker able to         insert and remove USB devices can use this to cause a denial of         service (crash or memory corruption) or possibly to run arbitrary         code in the kernel.

    CVE-2023-1118

        Duoming Zhou reported a race condition in the ene_ir remote         control driver that can lead to a use-after-free if the driver         is unbound.  It is not clear what the security impact of this is.

        valis reported two flaws in the cls_tcindex network traffic         classifier which could lead to a use-after-free.  A local user can         exploit these for privilege escalation.  This update removes         cls_tcindex entirely.

    CVE-2023-1513

        Xingyuan Mo reported an information leak in the KVM implementation         for the i386 (32-bit PC) architecture.  A local user could exploit         this to leak sensitive information from the kernel.

    CVE-2023-1611

        butt3rflyh4ck reported a race condition in the btrfs filesystem         driver which can lead to a use-after-free.  A local user could         exploit this to cause a denial of service (crash or memory         corruption) or possibly for privilege escalation.

    CVE-2023-1670

        Zheng Wang reported a race condition in the xirc2ps_cs network         driver which can lead to a use-after-free.  An attacker able to         insert and remove PCMCIA devices can use this to cause a denial of         service (crash or memory corruption) or possibly to run arbitrary         code in the kernel.

    CVE-2023-1855

        Zheng Wang reported a race condition in the xgene-hwmon hardware         monitoring driver that may lead to a use-after-free.  It is not         clear what the security impact of this is.

    CVE-2023-1859

        Zheng Wang reported a race condition in the 9pnet_xen transport         for the 9P filesystem on Xen, which can lead to a use-after-free.
        On systems where this feature is used, a backend driver in another         domain can use this to cause a denial of service (crash or memory         corruption) or possibly to run arbitrary code in the vulnerable         domain.

    CVE-2023-1872

        Bing-Jhong Billy Jheng reported a race condition in the io_uring         subsystem that can lead to a use-after-free.  A local user could         exploit this to cause a denial of service (crash or memory         corruption) or possibly for privilege escalation.

    CVE-2023-1989

        Zheng Wang reported a race condition in the btsdio Bluetooth         adapter driver that can lead to a use-after-free.  An attacker         able to insert and remove SDIO devices can use this to cause a         denial of service (crash or memory corruption) or possibly to run         arbitrary code in the kernel.

    CVE-2023-1990

        Zheng Wang reported a race condition in the st-nci NFC adapter         driver that can lead to a use-after-free.  It is not clear what         the security impact of this is.

        This driver is not enabled in Debian's official kernel         configurations.

    CVE-2023-1998

        Jos Oliveira and Rodrigo Branco reported a regression in Spectre         v2 mitigation for user-space on x86 CPUs supporting IBRS but not         eIBRS.  This might be exploitable by a local or remote attacker to         leak sensitive information from a user-space application.

    CVE-2023-2162

        Mike Christie reported a race condition in the iSCSI TCP transport         that can lead to a use-after-free.

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

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

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    The Linux kernel before 6.2.9 has a race condition and resultant use-after-free in     drivers/net/ethernet/qualcomm/emac/emac.c if a physically proximate attacker unplugs an emac based     device.(CVE-2023-33203)

    In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests     can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users     can obtain root privileges. This occurs because anonymous sets are mishandled.(CVE-2023-32233)

    A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the     extra inode size for extended attributes. This flaw could allow a privileged local user to cause a system     crash or other undefined behaviors.(CVE-2023-2513)

    A race condition vulnerability was found in the Linux kernel's Qualcomm EMAC Gigabit Ethernet Controller     when the user physically removes the device before cleanup in the emac_remove function. This flaw can     eventually result in a use-after-free issue, possibly leading to a system crash or other undefined     behaviors.(CVE-2023-2483)

    A speculative pointer dereference problem exists in the Linux Kernel on the do_prlimit() function. The     resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be     used to leak the contents. We recommend upgrading past version 6.1.8 or     commit739790605705ddcf18f21782b9c99ad7d53a8c11(CVE-2023-0458)

    An out-of-bounds memory access flaw was found in the Linux kernels traffic control (QoS) subsystem in     how a user triggers the qfq_change_class function with an incorrect MTU value of the network device used     as lmax. This flaw allows a local user to crash or potentially escalate their privileges on the     system.(CVE-2023-2248)

    qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write     because lmax can exceed QFQ_MIN_LMAX.(CVE-2023-31436)

    A use-after-free vulnerability was found in iscsi_sw_tcp_session_create in drivers/scsi/iscsi_tcp.c in     SCSI sub-component in the Linux Kernel. In this flaw an attacker could leak kernel internal     information.(CVE-2023-2162)

    Copy_from_user on 64-bit versions of the Linux kernel does not implement the __uaccess_begin_nospec     allowing a user to bypass the 'access_ok' check and pass a kernel pointer to copy_from_user(). This would     allow an attacker to leak information. We recommend upgrading beyond     commit74e19ef0ff8061ef55957c3abd71614ef0f42f47(CVE-2023-0459)

    A null pointer dereference issue was found in the sctp network protocol in net/sctp/stream_sched.c in     Linux Kernel. If stream_in allocation is failed, stream_out is freed which would further be accessed. A     local user could use this flaw to crash the system or potentially cause a denial of     service.(CVE-2023-2177)

    A denial of service problem was found, due to a possible recursive locking scenario, resulting in a     deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-     component.(CVE-2023-2269)

    An out-of-bounds memory access flaw was found in the Linux kernels XFS file system in how a user     restores an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or     potentially escalate their privileges on the system.(CVE-2023-2124)

    A vulnerability was found in compare_netdev_and_ip in drivers/infiniband/core/cma.c in RDMA in the Linux     Kernel. The improper cleanup results in out-of-boundary read, where a local user can utilize this problem     to crash the system or escalation of privilege.(CVE-2023-2176)

    An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The     userspace 'data-block[0]' variable was not capped to a number between 0-255 and was used as the size of     a memcpy, possibly writing beyond the end of dma_buffer. This flaw could allow a local privileged user to     crash the system or potentially achieve code execution.(CVE-2023-2194)

    The Linux kernel allows userspace processes to enable mitigations by calling prctl with     PR_SET_SPECULATION_CTRL which disables the speculation feature as well as by using seccomp. We had noticed     that on VMs of at least one major cloud provider, the kernel still left the victim process exposed to     attacks in some cases even after enabling the spectre-BTI mitigation with prctl. The same behavior can be     observed on a bare-metal machine when forcing the mitigation to IBRS on boot command line. This happened     because when plain IBRS was enabled (not enhanced IBRS), the kernel had some logic that determined that     STIBP was not needed. The IBRS bit implicitly protects against cross-thread branch target injection.
    However, with legacy IBRS, the IBRS bit was cleared on returning to userspace, due to performance reasons,     which disabled the implicit STIBP and left userspace threads vulnerable to cross-thread branch target     injection against which STIBP protects.(CVE-2023-1998)

    A flaw was found in the Linux kernel's udmabuf device driver. The specific flaw exists within a fault     handler. The issue results from the lack of proper validation of user-supplied data, which can result in a     memory access past the end of an array. An attacker can leverage this vulnerability to escalate privileges     and execute arbitrary code in the context of the kernel.(CVE-2023-2008)

    A use-after-free vulnerability in the Linux Kernel io_uring system can be exploited to achieve local     privilege escalation.
