A vulnerability in the Linux kernel's mac80211 wifi component related to handling empty FILS association request payloads has been resolved. The issue occurs when fils_encrypt_assoc_req() processes a (Re)Association Request frame with an empty FILS Session element, leading to a zero-length plaintext passed to aes_siv_encrypt(). This causes an invalid page to be placed into the scatterlist, potentially triggering a kernel BUG or passing a bogus page to the crypto backend. The fix involves properly handling the empty plaintext case before the CTR encryption step. Join the discussion | GCVE Database | 10/18/2026, 18:32:00 UTC Added: 10/18/2026, 19:40:28 UTC |
