USN-5302-1: Linux kernel (OEM) vulnerabilities<\/p>\n
Yiqi Sun and Kevin Wang discovered that the cgroups implementation in the
\nLinux kernel did not properly restrict access to the cgroups v1
\nrelease_agent feature. A local attacker could use this to gain
\nadministrative privileges. (CVE-2022-0492)<\/p>\n
Brendan Dolan-Gavitt discovered that the Marvell WiFi-Ex USB device driver
\nin the Linux kernel did not properly handle some error conditions. A
\nphysically proximate attacker could use this to cause a denial of service
\n(system crash). (CVE-2021-43976)<\/p>\n
Wenqing Liu discovered that the f2fs file system implementation in the
\nLinux kernel did not properly validate inode types while performing garbage
\ncollection. An attacker could use this to construct a malicious f2fs image
\nthat, when mounted and operated on, could cause a denial of service (system
\ncrash). (CVE-2021-44879)<\/p>\n
Samuel Page discovered that the Transparent Inter-Process Communication
\n(TIPC) protocol implementation in the Linux kernel contained a stack-based
\nbuffer overflow. A remote attacker could use this to cause a denial of
\nservice (system crash) for systems that have a TIPC bearer configured.
\n(CVE-2022-0435)<\/p>\n
Lyu Tao discovered that the NFS implementation in the Linux kernel did not
\nproperly handle requests to open a directory on a regular file. A local
\nattacker could use this to expose sensitive information (kernel memory).
