"baseSeverity": "HIGH" }, "scenarios": [ { "lang": "en", "value": "AV:L - The vulnerable parser is reached through the local V4L2 device nodes (/dev/video*) — session-init parsing on V1 hardware and core-init parsing after a driver-triggered firmware re-init — plus the HFI shared-memory queue from the on-die video co-processor; there is no network or physical-bus reachability.\nAC:L - No race and no dependence on uncontrolled memory layout: the attacker either supplies a payload with repeated CODEC_SUPPORTED properties (fully attacker-chosen index and value) or, on HFI_VERSION_1XX where codecs_count is never reset, simply loops session init/deinit until the counter exceeds MAX_CODEC_NUM; the driver is enabled in standard arm64/Android/embedded Qualcomm configurations.\nPR:L - Triggering the session-init parse path only requires opening the venus decoder/encoder node and issuing REQBUFS/STREAMON, which any local user in the video group (desktop uaccess ACL) or any Android app with normal mediacodec access can do — no root or capability is needed.\nUI:N - The attacker's own process drives the ioctl sequence and the firmware message handling runs asynchronously in the driver's IRQ/worker context; no victim action is involved.\nS:U - The out-of-bounds accesses corrupt and disclose kernel heap memory within the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Overflowing into codecs_count makes venus_caps_by_codec() iterate far past core->caps[], and the out-of-bounds hfi_plat_caps contents (formats, profile/levels, capability min/max) are handed back to userspace via V4L2 format and control enumeration, giving a broad kernel memory disclosure; the write primitive further enables leveraged reads.\nI:H - This is an out-of-bounds write with an attacker-controlled index (up to megabytes past a ~30 KB allocation) and attacker-selected power-of-two values, corrupting kernel pointers (core->root, core->ocs) and adjacent heap objects — a classic primitive for control-flow hijack.\nA:H - Corrupting codecs_count to a huge value causes an immediate unbounded scan of kernel memory, and clobbering the adjacent dentry/of_changeset pointers leads to an oops or panic on next use." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
