CVE-2022-0185 (GCVE-0-2022-0185)

Vulnerability from cvelistv5 – Published: 2022-02-11 17:40 – Updated: 2025-10-21 23:15
VLAI?
Summary
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.
Severity ?
