Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to the fixed version

Description A division by zero exception in the Linux kernel's wifi driver, specifically in the rtw89 module, has been resolved. The issue occurred during RF calibration, where a negative calibration result could cause a divisor of zero, leading to a core dump. The fix involves modifying the phy div function to only perform division if the divisor is not zero.

Recommendations For Linux kernel versions prior to the fixed version, consider applying the patch that fixes the division by zero exception in the rtw89 module. As a temporary workaround, disabling the wifi driver or restricting its use may help minimize the risk of exploitation. However, the most effective solution is to update to a version that includes the fix. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
