/dev/video* device node of the atomisp PCI ISP; there is no network or remote-peer path, and no physical interaction is required.\nAC:L - The attacker fully controls the ioctl arguments (embedded user pointers and width/height fields) and the device state (open, configure, stream, then issue the malicious ioctl), so the overflow can be triggered reliably with no conditions outside the attacker's control.\nPR:L - Private IOCTLs hit the vidioc_default path with flags=0 (no capability or priority check) and atomisp_open performs no capability check; an unprivileged local user holding the device-node ACL/video-group access (typical for the active desktop/camera session) can reach it without real root.\nUI:N - Exploitation is a self-contained sequence of ioctl calls by the attacker; no action by any other user is required.\nS:U - The corruption is confined to kernel memory within the same kernel security authority; there is no VM, IOMMU, or sandbox boundary crossing.\nC:H - The handlers provide kernel-heap out-of-bounds reads and the heap-overflow primitive can be leveraged to disclose adjacent kernel memory, enabling extensive information disclosure.\nI:H - atomisp_cp_dvs_6axis_config copies user-controlled-sized data into a smaller stream-sized heap allocation, giving a controlled kernel heap out-of-bounds write that can be leveraged for arbitrary write and code execution.\nA:H - The heap overflow corrupts kernel allocations and adjacent structures, readily causing a kernel oops/panic and full denial of service." } ] } ], "affected": [ { "product":
