CVE-2026-53329

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

drm/amd/display: Use krealloc_array() in dal_vector_reserve()

[Why & How]

dal_vector_reserve() computes the allocation size as

"capacity * vector->struct_size" using uint32_t arithmetic, which can

silently wrap to a small value on overflow. This would cause krealloc to

return a smaller buffer than expected, leading to heap overflows on

subsequent vector appends.

Replace krealloc() with krealloc_array() which performs an internal

overflow check and returns NULL on wrap, preventing the issue.
