Affected: kernel, linux_kernel

A heap-based buffer overflow flaw was found in the way the legacy_parse_param function in the Filesystem Context functionality of the Linux kernel verified the supplied parameters length. An unprivileged (in case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to legacy handling) could use this flaw to escalate their privileges on the system.

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)
