CVE-2026-98891In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: validate deauth frame length before reason access ieee80211_rx_mgmt_deauth() reads the... Executive summary The advisory describes a flaw in the Linux kernel's wireless networking code (mac80211) that can be reached by processing a received deauthentication frame. The advisory does not state how severe the flaw is, and the text shown describes a patch that validates the frame length before reading the reason code. Technical summary The flaw is in ieee80211_rx_mgmt_deauth(), which read the deauthentication reason code before checking that the fixed field was present in the received frame, a missing bounds check that is consistent with an out-of-bounds read. The fix moves the reason code read after a length check using offsetofend on the deauth reason_code field, and the patch is shown as a commit in the Linux kernel stable tree. The attack vector and preconditions are not stated, and the advisory does not describe an impact such as a crash or information leak. Affected and fixed kernel version numbers are not stated, workarounds are not stated, and no detection guidance is given. CVSS score and exploitation status are not stated. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.
