Description
In the Linux kernel, the following vulnerability has been resolved: PM / devfreq: Check governor before using governor->name Commit 96ffcdf239de ("PM / devfreq: Remove redundant governor_name from struct devfreq") removes governor_name and uses governor->name to replace it. But devfreq->governor may be NULL and directly using devfreq->governor->name may cause null pointer exception. Move the check of governor to before using governor->name.

Can you explain this vulnerability to me?

This vulnerability involves the Linux kernel's power management (PM) and devfreq subsystem. A code change removed a redundant governor_name field and replaced its usage with governor->name. However, the devfreq->governor pointer may be NULL, and using governor->name without checking if governor is NULL can cause a null pointer exception (crash). The fix was to add a check to ensure governor is not NULL before accessing governor->name.


How can this vulnerability impact me? :

If exploited, this vulnerability can cause a null pointer exception in the Linux kernel, potentially leading to a kernel crash or system instability. This could result in denial of service or unexpected system behavior.
