Overview
CVE-2026-93155 is a known-severity vulnerability. It was published on September 17, 2026.
Technical 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.

How can CyberStrike help with CVE-2026-93155?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-93155 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
