CVE-2024-58097: wifi: ath11k: fix RCU stall while reaping monitor destination ring
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 bufid.
However, sometimes the driver cannot obtain a valid buffer corresponding to the bufid received from the hardware. This causes an infinite loop in the destination processing, resulting in a kernel crash.
kernel log: ath11kpci 0000:58:00.0: data msdupop: invalid bufid 309 ath11kpci 0000:58:00.0: data dprxmonitorlinkdescreturn failed ath11kpci 0000:58:00.0: data msdupop: invalid bufid 309 ath11kpci 0000:58:00.0: data dprxmonitorlinkdescreturn failed
Fix this by skipping the problematic bufid and reaping the next entry, replacing the break with the next MSDU processing.
