Description: | Summary: The remote host is missing an update for the 'linux-intel-5.13' package(s) announced via the USN-5362-1 advisory.
Vulnerability Insight: Nick Gregory discovered that the Linux kernel incorrectly handled network offload functionality. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2022-25636)
Enrico Barberis, Pietro Frigo, Marius Muench, Herbert Bos, and Cristiano Giuffrida discovered that hardware mitigations added by ARM to their processors to address Spectre-BTI were insufficient. A local attacker could potentially use this to expose sensitive information. (CVE-2022-23960)
It was discovered that the BPF verifier in the Linux kernel did not properly restrict pointer types in certain situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-23222)
Max Kellermann discovered that the Linux kernel incorrectly handled Unix pipes. A local attacker could potentially use this to modify any file that could be opened for reading. (CVE-2022-0847)
Yiqi Sun and Kevin Wang discovered that the cgroups implementation in the Linux kernel did not properly restrict access to the cgroups v1 release_agent feature. A local attacker could use this to gain administrative privileges. (CVE-2022-0492)
William Liu and Jamie Hill-Daniel discovered that the file system context functionality in the Linux kernel contained an integer underflow vulnerability, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-0185)
Enrico Barberis, Pietro Frigo, Marius Muench, Herbert Bos, and Cristiano Giuffrida discovered that hardware mitigations added by Intel to their processors to address Spectre-BTI were insufficient. A local attacker could potentially use this to expose sensitive information. (CVE-2022-0001)
Jann Horn discovered a race condition in the Unix domain socket implementation in the Linux kernel that could result in a read-after-free. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-4083)
It was discovered that the NFS server implementation in the Linux kernel contained an out-of-bounds write vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-4090)
Kirill Tkhai discovered that the XFS file system implementation in the Linux kernel did not calculate size correctly when pre-allocating space in some situations. A local attacker could use this to expose sensitive information. (CVE-2021-4155)
It was discovered that the AMD Radeon GPU driver in the Linux kernel did not properly validate writes in the debugfs file system. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-42327)
Sushma Venkatesh Reddy discovered that the Intel i915 graphics driver in the Linux kernel did not ... [Please see the references for more information on the vulnerabilities]
