Description
This security bulletin contains information about 1 vulnerability.
1) Out-of-bounds read (CVE-ID: CVE-2026-98193)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 0 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to trigger an out-of-bounds read.
The vulnerability exists due to an unsigned payload length wraparound in libipw_michael_mic_verify() when processing short TKIP frames without a complete eight-byte Michael MIC. A remote attacker can send a short TKIP frame to trigger an out-of-bounds read in michael_mic() beyond the socket buffer.
The TKIP key must be set for the vulnerable verification path to run.
