CVE-2026-72456Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: apparmor: release exe file resources on path failure get_current_exe_path() takes both an exe_file reference and a path reference before resolving the path name. If aa_path_name() failed, it returned immediately and leaked both references. Route the failure through the common cleanup path so fput() and path_put() always run after the references are acquired. When the `get_current_exe_path()` function encounters a path resolution failure, it fails to properly release file and path references. This resource leak could be exploited by a local attacker, potentially leading to a Denial of Service (DoS) by exhausting system resources. Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).…
