CVE-2024-56543
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: Skip Rx TID cleanup for self peer
During peer create, dp setup for the peer is done where Rx TID is updated for all the TIDs. Peer object for self peer will not go through dp setup.
When core halts, dp cleanup is done for all the peers. While cleanup, rx_tid::ab is accessed which causes below stack trace for self peer.
sta object in peer will be updated when remote peer is created. Hence use peer::sta to detect the self peer and skip the cleanup.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1 Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
