CVE-2023-53664

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

Description A flaw exists in the Linux kernel related to a potential null pointer dereference within the dev pm opp get required pstate() function. The issue occurs because the opp pointer is dereferenced before a check to determine if it is an error or null. The fix involves removing the unnecessary dereference of the opp table cache and directly dereferencing it where it is used. This addresses a smatch warning indicating the potential for dereferencing a variable before an error check.

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