CVE-2023-53346 | BDVDB-2026-294273 Detail
LinuxLinux
Description#
In the Linux kernel, the following vulnerability has been resolved: kernel/fail_function: fix memory leak with using debugfs_lookup() When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call debugfs_lookup_and_remove() instead which handles all of the logic at once.
Impact#
Per CVSS v3.1: confidentiality impact none, integrity impact none, availability impact high. Attack vector: local.
Weaknesses#
- CWE-401 Missing Release of Memory after Effective Lifetime
