Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains an issue in the rtc subsystem, specifically within the msc313 rtc probe() function. A function prototype mismatch exists when calling clk disable unprepare(), which can lead to kernel panics or thread termination when kernel control flow integrity (kCFI) is enabled. This issue was identified using Clang’s -Wcast-function-type-strict flag, which detects stricter type mismatches than -Wcast-function-type. The issue was resolved by refactoring the code to use devm clk get enabled() instead.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
