CVE-2026-43113CVE-2026-43113
linux / linux_kernel
Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: wl1251: validate packet IDs before indexing tx_frames
wl1251_tx_packet_cb() uses the firmware completion ID directly to index
the fixed 16-entry wl->tx_frames[] array. The ID is a raw u8 from the
completion block, and the callback does not currently verify that it
fits the array before dereferencing it.
Reject completion IDs that fall outside wl->tx_frames[] and keep the
existing NULL check in the same guard. This keeps the fix local to the
trust boundary and avoids touching the rest of the completion flow.
