CVE-2026-53329

High

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. (cherry picked from commit 37668568641ccc4cc1dbca4923d0a16609dd5707)
