Loading vulnerability…
CVE-2024-58240 affects decryption-request handling in the Linux kernel TLS subsystem. The fix separates non-asynchronous processing from asynchronous processing, allowing the non-asynchronous path to wait for completion and return its result without reference counting, and recommends a separate crypto_wait structure. Potential consequences include local privilege escalation, arbitrary code execution, or denial of service, but the precise exploitation mechanism is not established. A use-after-free is not confirmed: the upstream change explicitly notes that a previously observed condition was believed to have been addressed by an earlier fix for a race between asynchronous notification and socket closure.
