CVE-2026-53329 is an integer-overflow vulnerability in dal_vector_reserve() in the Linux kernel AMD display DRM component. The function calculates the allocation size as capacity multiplied by vector->struct_size using uint32_t arithmetic. This multiplication can wrap to a smaller value, causing krealloc() to allocate an undersized buffer. Subsequent vector appends can then overflow the kernel heap buffer. The fix replaces krealloc() with krealloc_array(), which checks for allocation-size overflow and returns NULL when overflow occurs.
