GHSA-WG7X-4P3F-2W22

Vulnerability from github – Published: 2026-08-10 15:33 – Updated: 2026-08-19 18:32

Details

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

wifi: carl9170: fix OOB read from off-by-two in TX status handler

The bounds check in carl9170_tx_process_status() uses i > ((cmd->hdr.len / 2) + 1) which is off by two, allowing 2 extra iterations past valid _tx_status entries when the firmware- controlled hdr.ext exceeds hdr.len/2. Fix by using the correct comparison i >= (cmd->hdr.len / 2).
