Summary
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)`.
