CVE-2026-93155
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: crypto: keembay - Fix AEAD unregister count in error path register_aes_algs() registers the AEAD algorithms before registering the skcipher algorithms. If skcipher registration fails, the function unwinds the earlier AEAD registration with crypto_engine_unregister_aeads(), but it passes ARRAY_SIZE(algs), which is the skcipher table size. Use ARRAY_SIZE(algs_aead) for the AEAD unwind path so the unregister helper iterates over the same table that was registered. Also clarify the nearby comment: the crypto registration helpers clean up algorithms registered within the same call, while this function must still unwind earlier successful registration steps.
