    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.  A local user         could exploit this to cause a denial of service (crash or memory         corruption), to obtain sensitive information, or possibly for         privilege escalation.

    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-2022-3586 (ZDI-22-1452)

        The Linux Verification Center found a memory leak in the SAE J1939         protocol implementation.  A local user could exploit this to cause         a denial of service (resource exhaustion).

    CVE-2022-3635

        Several race conditions were discovered in the idt77252 ATM         driver, which can lead to a use-after-free if the module is         removed.  The security impact of this is unclear.

    CVE-2022-3649

        The syzbot tool found flaws in the nilfs2 filesystem driver which         can lead to a use-after-free.  A user permitted to mount arbitrary         filesystem images could use these to cause a denial of service         (crash or memory corruption) or possibly for privilege escalation.

    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-2022-20422

        A race condition was discovered in the instruction emulator for         64-bit Arm systems.  Concurrent changes to the sysctls that         control the emulator could result in a null pointer dereference.
        The security impact of this is unclear.

    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-2022-39190

        Gwangun Jung reported a flaw in the nf_tables subsystem.  A local         user could exploit this to cause a denial of service (crash).

    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-2022-41222

        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

        Soenke Huster discovered several vulnerabilities in the mac80211         subsystem triggered by WLAN frames which may result in denial of         service or the execution of arbitrary code.

    CVE-2022-43750

        The syzbot tool found that the USB monitor (usbmon) driver allowed         user-space programs to overwrite the driver's data structures.  A         local user permitted to access a USB monitor device could exploit         this to cause a denial of service (memory corruption or crash) or         possibly for privilege escalation.  However, by default only the         root user can access such devices.

    For Debian 10 buster, these problems have been fixed in version     5.10.149-2~deb10u1.  This update also fixes a regression for some     older 32-bit PCs (bug #1017425), and enables the i10nm_edac driver     (bug #1019248).  It additionally includes many more bug fixes from     stable updates 5.10.137-5.10.149 inclusive.

    We recommend that you upgrade your linux-5.10 packages.

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 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.
