CVE-2007-4774 — The Linux kernel before 2.4.36-rc1 has a race condition

Matched remediation archetype

Race condition, TOCTOU, and lifecycle synchronization

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

• Map concurrent actors, shared state, lock boundaries, signals, callbacks, retries, and check-then-use sequences in the affected path.
• Determine whether untrusted users can influence timing, object names, filesystem state, or repeated state transitions.
• Identify clustered and multi-process behavior that repository-local tests may not represent.

Remediate safely

• Make the sensitive state transition atomic or protect it with a consistently ordered synchronization primitive.
• Perform authorization and invariant checks on the same authoritative object and transaction used for the operation.
• Use unique private resources, safe ownership transfer, and idempotent operations; add deterministic concurrency regression tests.
