Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
wifi: ath12k: Correct tid cleanup when tid setup fails<br />
<br />
Currently, if any error occurs during ath12k_dp_rx_peer_tid_setup(),<br />
the tid value is already incremented, even though the corresponding<br />
TID is not actually allocated. Proceed to<br />
ath12k_dp_rx_peer_tid_delete() starting from unallocated tid,<br />
which might leads to freeing unallocated TID and cause potential<br />
crash or out-of-bounds access.<br />
<br />
Hence, fix by correctly decrementing tid before cleanup to match only<br />
the successfully allocated TIDs.<br />
<br />
Also, remove tid-- from failure case of ath12k_dp_rx_peer_frag_setup(),<br />
as decrementing the tid before cleanup in loop will take care of this.<br />
<br />
Compile tested only.
