Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.4.89
Description
A kernel panic issue has been resolved in the Linux kernel. The problem occurred during the unload and load of ath11k modules, causing a kernel panic due to an internal error. The issue was related to the
napi by id function and the netif napi add function. The error was triggered when the ath11k ahb config irq function was called, leading to a crash. The issue was identified on a Generic DT based system with a CPU PID of 4435.Recommendations
For Linux kernel version 5.4.89 and earlier, update to a newer version to resolve the issue. As a temporary workaround, consider disabling the
ath11k ahb config irq function until a patch is available. Restrict access to the ath11k ahb module to minimize the risk of exploitation. Avoid using the napi by id function in the affected API endpoint until the issue is resolved.Exploit
