CVE-2026-97427

Estado: RecibidaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/pm: bound pp_dpm_set_pp_table() memcpy

The powerplay path allocates hardcode_pp_table once with kmemdup(..., soft_pp_table_size). memcpy(..., size) used the sysfs store count (up to PAGE_SIZE) with no upper bound, causing heap overflow. Reject writes where size exceeds soft_pp_table_size.
