CVE-2024-22365: n/a
linux-pam (aka Linux PAM) before 1.6.0 allows attackers to cause a denial of service (blocked login process) via mkfifo because the openat call (for protect_dir) lacks O_DIRECTORY.
AI Analysis
Technical Summary
CVE-2024-22365 is a medium severity vulnerability in linux-pam versions prior to 1.6.0. The flaw arises from the openat call in the protect_dir function lacking the O_DIRECTORY flag, which can be exploited by an attacker with local privileges using mkfifo to cause a denial of service by blocking login processes. The vulnerability is classified under CWE-664 (Improper Control of a Resource Through its Lifetime). No known exploits are reported in the wild, and no vendor or patch information is currently available.
Potential Impact
The vulnerability allows a local attacker with low privileges to cause a denial of service, specifically blocking login processes, which impacts system availability. There is no impact on confidentiality or integrity according to the CVSS vector.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict local access to trusted users only and monitor for suspicious use of mkfifo or abnormal login failures related to PAM.
