Positive Technologies (AI Summary)

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

Description An issue exists in the drm/i915/gem component where the sg page() function returns a struct page pointer instead of a void pointer. This causes incorrect scaling during pread and pwrite operations for physical Buffer Objects (BO), leading to the access of incorrect BO segments when a non-zero offset is utilized. This affects platforms using physical mapping for overlay or cursor planes, such as Gen3/945G/Lakeport.

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