Vulnerability from github – Published: 2026-02-14 18:30 – Updated: 2026-02-14 18:30

Details

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

wifi: mac80211: correctly decode TTLM with default link map

TID-To-Link Mapping (TTLM) elements do not contain any link mapping presence indicator if a default mapping is used and parsing needs to be skipped.

Note that access points should not explicitly report an advertised TTLM with a default mapping as that is the implied mapping if the element is not included, this is even the case when switching back to the default mapping. However, mac80211 would incorrectly parse the frame and would also read one byte beyond the end of the element.
