CVE-2026-80635
In the Linux kernel, the following vulnerability has been resolved: wifi: wcn36xx: fix OOB read from short trigger BA firmware response The firmware response
In the Linux kernel, the following vulnerability has been resolved:
wifi: wcn36xx: fix OOB read from short trigger BA firmware response
The firmware response length is only checked against sizeof(*rsp) (20
bytes), but when candidate_cnt >= 1, a 22-byte candidate struct is read
at buf + 20 without verifying the response contains it. This causes an
out-of-bounds read of stale heap data, corrupting the BA session state.
Add validation that the response includes the candidate data.
