"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Use krealloc_array() in dal_vector_reserve()\n\n[Why & How]\ndal_vector_reserve() computes the allocation size as\n\"capacity * vector->struct_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)"

"value": "AV:L - The reachable kernel path is AMDGPU DRM display handling via local DRM connector probing or modeset operations; it is not network or namespace reachable. Physical hotplug can also reach related detection paths, but local DRM access is the higher-severity reasonable vector.\nAC:H - The overflow is deterministic once vector capacity crosses the uint32 multiplication limit, but the reachable DDC callers I found pass fixed tiny payload lengths and an attacker would need an unusual path causing enormous vector growth. That prerequisite is outside normal attacker control.\nPR:L - Triggering the relevant DRM display paths requires local access to the KMS device or DRM master-style display control, not real root in the init namespace. No user-namespace route or network-facing unauthenticated path reaches this code.\nUI:N - A local attacker who has the needed DRM access can trigger connector probing or modeset paths directly. No separate victim action is required.\nS:U - The corruption occurs inside the host kernel display driver and affects the same kernel security authority. There is no VM escape, IOMMU boundary bypass, or cross-scope component involved.\nC:H - The vulnerable allocation can leave the vector with a logical capacity larger than its actual heap buffer, and subsequent appends can corrupt adjacent kernel heap memory. Kernel heap corruption is reasonably leverageable for information disclosure.\nI:H - Subsequent vector appends perform out-of-bounds writes of controlled `struct i2c_payload` contents into adjacent kernel heap memory. That is kernel memory corruption and can plausibly support control-flow or data-integrity compromise.\nA:H - Even without full exploitation, the undersized allocation followed by appends can corrupt heap metadata or neighboring objects. That can cause kernel oops, panic, or display-driver crashes."
