Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.4.0-kasan 438-g3303d06107f3+

Description The Linux kernel contains an issue within the drm/i915/perf subsystem related to the handling of arrays passed to the reg in range table. Specifically, these arrays were not properly terminated with an empty record, leading to a potential out-of-bounds read when validating addresses using the xehp is valid b counter addr function. This resulted in a Kernel Address Sanitizer (KASAN) detected bug. The issue was addressed by adding a sentinel to the xehp oa b counters.

Recommendations Update to version 6.4.0-kasan 438-g3303d06107f3+ or later to resolve this issue.
