Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A vulnerability in the Linux kernel has been resolved, specifically in the wifi: ath12k module. The issue occurs when there is an error during firmware initialization, causing the
ath12k dp cc cleanup function to be called to release resources. However, this release is done again when the device is unbound, resulting in a kernel NULL pointer dereference. The problem is always reproducible from a virtual machine due to failing MSI addressing initialization.Recommendations
To fix the issue, set the released structure to NULL in the
ath12k dp cc cleanup function at the end. This will prevent the kernel NULL pointer dereference and resolve the vulnerability.Exploit
