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.
