Description

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath11k: fix RCU stall while reaping monitor destination ring

While processing the monitor destination ring, MSDUs are reaped from the link descriptor based on the corresponding buf_id.

However, sometimes the driver cannot obtain a valid buffer corresponding to the buf_id received from the hardware. This causes an infinite loop in the destination processing, resulting in a kernel crash.

kernel log: ath11k_pci 0000:58:00.0: data msdu_pop: invalid buf_id 309 ath11k_pci 0000:58:00.0: data dp_rx_monitor_link_desc_return failed ath11k_pci 0000:58:00.0: data msdu_pop: invalid buf_id 309 ath11k_pci 0000:58:00.0: data dp_rx_monitor_link_desc_return failed

Fix this by skipping the problematic buf_id and reaping the next entry, replacing the break with the next MSDU processing.
