filelock: StrictSoftFileLock and SoftReadWriteLock adopt a protocol directory another user created first, losing mutual exclusion

StrictSoftFileLock, AsyncStrictSoftFileLock, SoftReadWriteLock and AsyncSoftReadWriteLock keep their whole ownership state as files in a directory derived from the lock path .filelock/claims, .rw/gen,holders. When that directory already exists they adopt it after checking only that it is a real...

SUSE CVE-2026-112941

filelock is a platform-independent file lock for Python. From 4.1.0 until 4.2.1, SoftReadWriteLock and AsyncSoftReadWriteLock cache a successful check of the .rw lock tree and resolve its names again during later record operations, allowing another local user who can replace that tree after the...

Linux Distros Unpatched Vulnerability : CVE-2026-112941

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - filelock is a platform-independent file lock for Python. From 4.1.0 until 4.2.1, SoftReadWriteLock and AsyncSoftReadWriteLock cache a successful check of the .r...

CVE-2026-112941

A flaw was found in filelock. The SoftReadWriteLock and AsyncSoftReadWriteLock mechanisms cache an initial directory check but resolve path names again during subsequent record operations. A local attacker can exploit this behavior by replacing the lock directory structure after its initial...

tox-dev filelock: race condition issue

The tox-dev filelock version 4.1.0 to 4.2.1 had a race condition issue. This issue stemmed from the SoftReadWriteLock and AsyncSoftReadWriteLock classes’ caching mechanism for checking the .rw lock tree successfully, and then re-reshaping its name during subsequent recording operations. This coul...
