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

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

Scope
Notes: KEV entry: Linux Kernel Heap-Based Buffer Overflow Vulnerability | Affected: Linux / Kernel | Description: 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. | Required action: Apply updates per vendor instructions or discontinue use of the product if updates are unavailable. | Due date: 2024-09-11 | Known ransomware campaign use (KEV): Unknown | Notes (KEV): This vulnerability affects a common open-source component, third-party library, or a protocol used by different products.
