AI-suggested
A fix is available that rejects writes exceeding the allocated buffer size. Users should apply the official Linux kernel updates that include this patch. Since this is not a cloud service, system administrators must update affected Linux kernel versions to remediate the issue.
Description
A heap overflow vulnerability in the Linux kernel's AMD DRM powerplay component was resolved. The issue involved an unbounded memcpy operation in the pp_dpm_set_pp_table() function, where the copy size was controlled by a sysfs store count without an upper bound, potentially exceeding the allocated buffer size. The fix rejects writes where the size exceeds the allocated soft_pp_table_size.
