CVE-2025-68729

Description

In the Linux kernel, the following vulnerability has been resolved:wifi: ath12k: Fix MSDU buffer types handling in RX error pathCurrently, packets received on the REO exception ring fromunassociated peers are of MSDU buffer type, while the driver expectslink descriptor type packets. These packets are not parsed further dueto a return check on packet type in ath12k_hal_desc_reo_parse_err(),but the associated skb is not freed. This may lead to kernelcrashes and buffer leaks.Hence to fix, update the RX error handler to explicitly dropMSDU buffer type packets received on the REO exception ring.This prevents further processing of invalid packets and ensuresstability in the RX error handling path.Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1
