  3. CVE-2024-56543
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. WARNING: CPU: 6 PID: 12297 at drivers/net/wireless/ath/ath12k/dp_rx.c:851 Call Trace: __warn+0x7b/0x1a0 ath12k_dp_rx_frags_cleanup+0xd2/0xe0 [ath12k] report_bug+0x10b/0x200 handle_bug+0x3f/0x70 exc_invalid_op+0x13/0x60 asm_exc_invalid_op+0x16/0x20 ath12k_dp_rx_frags_cleanup+0xd2/0xe0 [ath12k] ath12k_dp_rx_frags_cleanup+0xca/0xe0 [ath12k] ath12k_dp_rx_peer_tid_cleanup+0x39/0xa0 [ath12k] ath12k_mac_peer_cleanup_all+0x61/0x100 [ath12k] ath12k_core_halt+0x3b/0x100 [ath12k] ath12k_core_reset+0x494/0x4c0 [ath12k] sta object in peer will be updated when remote peer is created.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: ath12k: Omitir desinfección de TID de Rx para peer propio Durante la creación del peer, se realiza la configuración de dp para el peer donde se actualiza el TID de Rx para todos los TID. El objeto peer para el peer propio no pasará por la configuración de dp. Cuando el núcleo se detiene, se realiza la desinfección de dp para todos los peers. Durante la desinfección, se accede a rx_tid::ab, lo que provoca el siguiente seguimiento de pila para el peer propio. ADVERTENCIA: CPU: 6 PID: 12297 en drivers/net/wireless/ath/ath12k/dp_rx.c:851 Seguimiento de llamadas: __warn+0x7b/0x1a0 ath12k_dp_rx_frags_cleanup+0xd2/0xe0 [ath12k] report_bug+0x10b/0x200 handle_bug+0x3f/0x70 exc_invalid_op+0x13/0x60 asm_exc_invalid_op+0x16/0x20 ath12k_dp_rx_frags_cleanup+0xd2/0xe0 [ath12k] ath12k_dp_rx_frags_cleanup+0xca/0xe0 [ath12k] ath12k_dp_rx_peer_tid_cleanup+0x39/0xa0 [ath12k] ath12k_mac_peer_cleanup_all+0x61/0x100 [ath12k] ath12k_core_halt+0x3b/0x100 [ath12k] ath12k_core_reset+0x494/0x4c0 [ath12k] El objeto sta en el peer se actualizará cuando se cree el peer remoto. Por lo tanto, use peer::sta para detectar el peer propio y omitir la desinfección.
