Name of the Vulnerable Software and Affected Versions Linux Kernel (affected versions not specified)
Description A flaw exists in the Linux kernel’s PM / devfreq subsystem, specifically within the mtk-cci component. The drv->sram reg pointer could be assigned an error value, potentially leading to a dereference of an invalid memory location. The issue is addressed by implementing a check using IS ERR OR NULL() to ensure the pointer’s validity before use.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
