CISA 원문
Linux kernel contains a heap-based buffer overflow vulnerability in the legacy_parse_param function in the Filesystem Context functionality. This allows an attacker to open a filesystem that does not support the Filesystem Context API and ultimately escalate privileges.— CISA KEV · shortDescription 원문
Apply updates per vendor instructions or discontinue use of the product if updates are unavailable.— CISA KEV · requiredAction 원문
취약점 설명 (NVD 원문)
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.
