CVE-2026-98193

Not scored yetLast modified Oct 21, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

wifi: libipw: reject TKIP frames without a full MIC

libipw_michael_mic_verify() assumes that an skb contains an eight-byte Michael MIC. A short TKIP frame makes the unsigned payload length wrap, causing michael_mic() to read past the skb.

Check that the MIC is present before verifying it, and use the existing MICHAEL_MIC_LEN constant for all MIC lengths in the verifier.
