  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Use krealloc_array() in dal_vector_reserve()\n\n[Why \u0026 How]\ndal_vector_reserve() computes the allocation size as\n\"capacity * vector-\u003estruct_size\" using uint32_t arithmetic, which can\nsilently wrap to a small value on overflow. This would cause krealloc to\nreturn a smaller buffer than expected, leading to heap overflows on\nsubsequent vector appends.\n\nReplace krealloc() with krealloc_array() which performs an internal\noverflow check and returns NULL on wrap, preventing the issue.\n\n(cherry picked from commit 37668568641ccc4cc1dbca4923d0a16609dd5707)",
