CVE-2026-53329

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/amd/display: Use krealloc_array() in dal_vector_reserve()<br /> <br /> [Why &amp; How]<br /> dal_vector_reserve() computes the allocation size as<br /> "capacity * vector-&gt;struct_size" using uint32_t arithmetic, which can<br /> silently wrap to a small value on overflow. This would cause krealloc to<br /> return a smaller buffer than expected, leading to heap overflows on<br /> subsequent vector appends.<br /> <br /> Replace krealloc() with krealloc_array() which performs an internal<br /> overflow check and returns NULL on wrap, preventing the issue.<br /> <br /> (cherry picked from commit 37668568641ccc4cc1dbca4923d0a16609dd5707)
