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.
