CVE-2026-98270

The Linux kernel contains a vulnerability in the drm/amdgpu component where the function nbio_v7_9_handle_ras_controller_intr_no_bifring() dereferences ras and obj without performing NULL checks. This occurs because amdgpu_ras_get_context() and amdgpu_ras_find_obj() can return NULL during a speci...

CVE-2026-98243

A vulnerability exists in the Linux kernel 's dma-buf/dma-fence component. A previous patch intended to prevent a NULL pointer dereference by testing the ops pointer instead of the signaled bit inadvertently removed RCU protection for many dma_fence implementations. This loss of protection can le...
