In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix init ordering in amdgpuvrammgrinit drmmcgroupregisterregion is called before INITLISTHEAD and gpubuddyinit in amdgpuvrammgrinit. If it fails, the function returns early and bypasses those initializations. Since...

CVE-2026-89828

This CVE affects the Linux kernel's amdgpu DRM driver . The root cause is an initialization ordering bug in amdgpu_vram_mgr_init(): the function drmm_cgroup_register_region() is called before the list heads and buddy allocator are initialized. If it fails, the early return skips those initializat...

CVE-2026-89826 drm/panthor: harden firmware build-info bounds checks

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: harden firmware build-info bounds checks panthorfwreadbuildinfo checks whether the metadata range fits in the firmware image with hdr.metastart + hdr.metasize. Both fields are u32, so the addition can wrap and let an...

CVE-2026-89826

This vulnerability affects the Linux kernel 's drm/panthor GPU driver, specifically the panthor_fw_read_build_info() function. Two related flaws allow an out-of-bounds memory read: (1) the metadata range validation uses addition of two u32 fields (hdr.meta_start + hdr.meta_size), which can wrap a...
