CVE-2026-93155: crypto: keembay - Fix AEAD unregister count in error path

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.21% (FIRST EPSS).
  • Fixed version: Linux Linux 27ec91c29ee155cc507b2f56221fc6fab65dbb51, 5607b101d86cbee8dd1ffab784495c880ca73383, 5bbb726d27ff6dff750264e51aa665538394d0f8.

Low priority for now. Upgrade to Linux Linux 27ec91c29ee155cc507b2f56221fc6fab65dbb51, 5607b101d86cbee8dd1ffab784495c880ca73383, 5bbb726d27ff6dff750264e51aa665538394d0f8 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
