Linux Kernel Heap-Based Buffer Overflow Vulnerability (CVE-2022-0185)
Severity: high · Patch status: patched · Since 2024-08-21 · CVE-2022-0185
Linux kernel contains a heap-based buffer overflow vulnerability in the legacyparseparam 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 added CVE-2022-0185 to its Known Exploited Vulnerabilities catalog on Aug 21, 2024, which means attackers are exploiting it in the wild.
What to do
- Apply updates per vendor instructions or discontinue use of the product if updates are unavailable.
- US federal agencies must remediate by Sep 11, 2024 (BOD 22-01); treat that as the outer limit.
