CVE-2026-53329 is a Linux kernel vulnerability in the drm/amd/display subsystem. The flaw is in dal_vector_reserve(), which calculates a reallocation size as capacity multiplied by vector->struct_size using 32-bit unsigned arithmetic. If that multiplication overflows, the computed size can wrap to a smaller value without detection. The code then passes the truncated size to krealloc(), which may return a buffer smaller than the caller expects. Subsequent vector append operations can then write past the end of the allocated heap buffer, resulting in a heap overflow. The issue was fixed by replacing krealloc() with krealloc_array(), which performs checked array-size multiplication and fails safely on overflow.
