Summary
In the Linux kernel, the following vulnerability has been resolved: nvkm/gsp: correctly advance the read pointer of GSP message queue A GSP event message consists three parts: message header, RPC header, message body. GSP calculates the number of pages to write from the total size of a GSP message. This behavior can be observed from the movement of the write pointer. However, nvkm takes only the size of RPC header and message body as the message size when advancing the read pointer. When handling a two-page GSP message in the non rollback case, It wrongly takes the message body of the previous message as the message header of the next message. As the "message length" tends to be zero, in the calculation of size needs to be copied (0 - size of (message header)), the size needs to be copied will be "0xffffffxx". It also triggers a kernel panic due to a NULL pointer error. [ 547.614102] msg: 00000f90: ff ff ff ff ff ff ff ff 40 d7 18 fb 8b 00 00 00 ........@.......

              "value": "AV:L - The GSP message queue is driven by the nouveau kernel driver on behalf of local DRM clients via /dev/dri/card* and renderD* ioctls (channel alloc, VMM ops, RC/fault events), with processing in a local workqueue off the GPU interrupt. There is no network or adjacent-network exposure.\nAC:L - The desync is deterministic for any GSP message whose RPC payload lands in the 48-byte-per-page window, and the rollback/wrap case mis-advances the pointer for every two-page message; a local client can generate sustained GSP command and event traffic of varying sizes to reach that condition. No race or attacker-uncontrollable memory layout is required.\nPR:L - Only an unprivileged local user with access to the DRM render node is needed \u2014 no capability check, root, or namespace trick is involved, and render nodes are routinely available to logged-in desktop users and GPU-passthrough containers.\nUI:N - The faulty message-queue parsing runs asynchronously in r535_gsp_msgq_work from the GSP interrupt handler; no victim action beyond the attacker\u0027s own ioctls is required.\nS:U - The corruption and crash are confined to the host kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The read-pointer desync makes the driver parse arbitrary out-of-band ring bytes as an RPC header, and the resulting `msg-\u003elength - sizeof(*msg)` underflow bypasses the `WARN_ON(repc \u003c sizeof(*msg))` guards, handing a ~4 GiB size to notifier callbacks that read past small allocations and forward `eventData`/`eventDataSize` to client event handlers, leaking kernel memory.\nI:H - A misparsed message dispatched to r535_gsp_msg_run_cpu_sequencer() performs `nvkm_wr32(device, addr, data)` (an unchecked `iowrite32_native` at an unvalidated BAR offset) and `seq-\u003eregSaveArea[slot] = ...` with an unvalidated index \u2014 an out-of-bounds write usable to corrupt kernel memory and device state.\nA:H - The commit reproduces a supervisor page fault at 0x20 in r535_gsp_msg_recv() (ZERO_SIZE_PTR from `kvmalloc(0)`) leading to an oops and \"Kernel panic - not syncing: Fatal exception\", and the persistent queue desync keeps the GPU driver broken thereafter."
