CVE-2024-22365: pam: pam_namespace misses O_DIRECTORY flag in `protect_dir()` (CVE-2024-22365)
First published: Wed Jan 10 2024(Updated: )
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.
