The remote NewStart CGSL host, running version MAIN 6.06, has kernel packages installed that are affected by multiple vulnerabilities:

  - There are use-after-free vulnerabilities in the Linux kernel's net/bluetooth/l2cap_core.c's l2cap_connect     and l2cap_le_connect_req functions which may allow code execution and leaking kernel memory (respectively)     remotely via Bluetooth. A remote attacker could execute code leaking kernel memory via Bluetooth if within     proximity of the victim. We recommend upgrading past commit https://www.google.com/url     https://github.com/torvalds/linux/commit/711f8c3fb3db61897080468586b970c87c61d9e4     https://www.google.com/url (CVE-2022-42896)

  - An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init     (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different     vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an     unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data     in net/netfilter/nf_tables_api.c. (CVE-2022-34918)

  - When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of     bounds. (CVE-2021-33655)

  - When setting font with malicous data by ioctl cmd PIO_FONT,kernel will write memory out of bounds.
    (CVE-2021-33656)

  - A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that     allows local users to create files for the XFS file-system with an unintended group ownership and with     group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a     certain group and is writable by a user who is not a member of this group. This can lead to excessive     permissions granted in case when they should not. This vulnerability is similar to the previous     CVE-2018-13405 and adds the missed fix for the XFS. (CVE-2021-4037)

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

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5257 advisory.

    Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation,     denial of service or information leaks. CVE-2021-4037 Christian Brauner reported that the inode_init_owner     function for the XFS filesystem in the Linux kernel allows local users to create files with an unintended     group ownership allowing attackers to escalate privileges by making a plain file executable and SGID.
    CVE-2022-0171 Mingwei Zhang reported that a cache incoherence issue in the SEV API in the KVM subsystem     may result in denial of service. CVE-2022-1184 A flaw was discovered in the ext4 filesystem driver which     can lead to a use-after-free. A local user permitted to mount arbitrary filesystems could exploit this to     cause a denial of service (crash or memory corruption) or possibly for privilege escalation. CVE-2022-2602     A race between handling an io_uring request and the Unix socket garbage collector was discovered. An     attacker can take advantage of this flaw for local privilege escalation. CVE-2022-2663 David Leadbeater     reported flaws in the nf_conntrack_irc connection-tracking protocol module. When this module is enabled on     a firewall, an external user on the same IRC network as an internal user could exploit its lax parsing to     open arbitrary TCP ports in the firewall, to reveal their public IP address, or to block their IRC     connection at the firewall. CVE-2022-3061 A flaw was discovered in the i740 driver which may result in     denial of service. This driver is not enabled in Debian's official kernel configurations. CVE-2022-3176 A     use-after-free flaw was discovered in the io_uring subsystem which may result in local privilege     escalation to root. CVE-2022-3303 A race condition in the snd_pcm_oss_sync function in the sound subsystem     in the Linux kernel due to improper locking may result in denial of service. CVE-2022-20421 A use-after-     free vulnerability was discovered in the binder_inc_ref_for_node function in the Android binder driver. On     systems where the binder driver is loaded, a local user could exploit this for privilege escalation.
    CVE-2022-39188 Jann Horn reported a race condition in the kernel's handling of unmapping of certain memory     ranges. When a driver created a memory mapping with the VM_PFNMAP flag, which many GPU drivers do, the     memory mapping could be removed and freed before it was flushed from the CPU TLBs. This could result in a     page use-after-free. A local user with access to such a device could exploit this to cause a denial of     service (crash or memory corruption) or possibly for privilege escalation. CVE-2022-39842 An integer     overflow was discovered in the pxa3xx-gcu video driver which could lead to a heap out-of-bounds write.
    This driver is not enabled in Debian's official kernel configurations. CVE-2022-40307 A race condition was     discovered in the EFI capsule-loader driver, which could lead to use-after-free. A local user permitted to     access this device (/dev/efi_capsule_loader) could exploit this to cause a denial of service (crash or     memory corruption) or possibly for privilege escalation. However, this device is normally only accessible     by the root user. CVE-2022-41674, CVE-2022-42719, CVE-2022-42720, CVE-2022-42721, CVE-2022-42722 Soenke     Huster discovered several vulnerabilities in the mac80211 subsystem triggered by WLAN frames which may     result in denial of service or the execution or arbitrary code. For the stable distribution (bullseye),     these problems have been fixed in version 5.10.149-1. We recommend that you upgrade your linux packages.

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

    CVE-2021-4037

        Christian Brauner reported that the inode_init_owner function for         the XFS filesystem in the Linux kernel allows local users to         create files with an unintended group ownership allowing attackers         to escalate privileges by making a plain file executable and SGID.

    CVE-2022-0171

        Mingwei Zhang reported that a cache incoherence issue in the SEV         API in the KVM subsystem may result in denial of service.

    CVE-2022-1184

        A flaw was discovered in the ext4 filesystem driver which can lead         to a use-after-free. A local user permitted to mount arbitrary         filesystems could exploit this to cause a denial of service (crash         or memory corruption) or possibly for privilege escalation.

    CVE-2022-1679

        The syzbot tool found a race condition in the ath9k_htc driver         which can lead to a use-after-free.  This might be exploitable to         cause a denial service (crash or memory corruption) or possibly         for privilege escalation.

    CVE-2022-2153

        kangel reported a flaw in the KVM implementation for x86         processors which could lead to a null pointer dereference. A local         user permitted to access /dev/kvm could exploit this to cause a         denial of service (crash).

    CVE-2022-2602

        A race between handling an io_uring request and the Unix socket         garbage collector was discovered. An attacker can take advantage         of this flaw for local privilege escalation.

    CVE-2022-2663

        David Leadbeater reported flaws in the nf_conntrack_irc         connection-tracking protocol module. When this module is enabled         on a firewall, an external user on the same IRC network as an         internal user could exploit its lax parsing to open arbitrary TCP         ports in the firewall, to reveal their public IP address, or to         block their IRC connection at the firewall.

    CVE-2022-2905

        Hsin-Wei Hung reported a flaw in the eBPF verifier which can lead         to an out-of-bounds read.  If unprivileged use of eBPF is enabled,         this could leak sensitive information.  This was already disabled         by default, which would fully mitigate the vulnerability.

    CVE-2022-3028

        Abhishek Shah reported a race condition in the AF_KEY subsystem,         which could lead to an out-of-bounds write or read.

    CVE-2022-40307

        A race condition was discovered in the EFI capsule-loader driver,         which could lead to use-after-free. A local user permitted to         access this device (/dev/efi_capsule_loader) could exploit this to         cause a denial of service (crash or memory corruption) or possibly         for privilege escalation. However, this device is normally only         accessible by the root user.

    CVE-2022-41222

        A race condition was discovered in the memory management subsystem         that can lead to stale TLB entries.  A local user could exploit         this to cause a denial of service (memory corruption or crash),         information leak, or privilege escalation.

    CVE-2022-41674, CVE-2022-42719, CVE-2022-42720, CVE-2022-42721,     CVE-2022-42722

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.

The version of kernel installed on the remote host is prior to 5.10.147-133.644. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2022-021 advisory.

    A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that     allows local users to create files for the XFS file-system with an unintended group ownership and with     group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a     certain group and is writable by a user who is not a member of this group. This can lead to excessive     permissions granted in case when they should not.  This vulnerability is similar to the previous     CVE-2018-13405 and adds the missed fix for the XFS. (CVE-2021-4037)

    A flaw was found in the Linux kernel. The existing KVM SEV API has a vulnerability that allows a non-root     (host) user-level application to crash the host kernel by creating a confidential guest VM instance in AMD     CPU that supports Secure Encrypted Virtualization (SEV). (CVE-2022-0171)

    A use-after-free flaw was found in the Linux kernel's Unix socket Garbage Collection and io_uring. This     flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-2602)

    Found Linux Kernel flaw in the i740 driver. The Userspace program could pass any values to the driver     through ioctl() interface. The driver doesn't check the value of 'pixclock', so it may cause a divide by     zero error. (CVE-2022-3061)

    A vulnerability, which was classified as problematic, was found in Linux Kernel. Affected is the function     damon_sysfs_add_target of the file mm/damon/sysfs.c of the component Netfilter. The manipulation leads to     memory leak. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is     VDB-211044. (CVE-2022-3544)

    An issue was discovered in the Linux kernel before 5.19. In pxa3xx_gcu_write in     drivers/video/fbdev/pxa3xx-gcu.c, the count parameter has a type conflict of size_t versus int, causing an     integer overflow and bypassing the size check. After that, because it is used as the third argument to     copy_from_user(), a heap overflow may occur. (CVE-2022-39842)

    This vulnerability allows local attackers to disclose sensitive information on affected installations of     the Linux Kernel 6.0-rc2. An attacker must first obtain the ability to execute high-privileged code on the     target system in order to exploit this vulnerability. The specific flaw exists within the nft_osf_eval     function. The issue results from the lack of proper initialization of memory prior to accessing it. An     attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the     context of the kernel. Was ZDI-CAN-18540. (CVE-2022-42432)

    of: fdt: fix off-by-one error in unflatten_dt_nodes() (CVE-2022-48672)

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

    vfio/type1: Unpin zero pages (CVE-2022-48700)

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

    io_uring/af_unix: defer registered files gc to io_uring release (CVE-2022-50234)

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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A flaw was found in the Linux kernel. The existing KVM SEV API has a vulnerability that allows a non-root     (host) user-level application to crash the host kernel by creating a confidential guest VM instance in AMD     CPU that supports Secure Encrypted Virtualization (SEV). (CVE-2022-0171)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of kernel-generic installed on the remote host is prior to 5.15.80 / 5.15.80_smp. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2022-333-01 advisory.
