"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Handle dml allocation failure to avoid crash\n\n[Why]\nIn the case where a dml allocation fails for any reason, the\ncurrent state's dml contexts would no longer be valid. Then\nsubsequent calls dc_state_copy_internal would shallow copy\ninvalid memory and if the new state was released, a double\nfree would occur.\n\n[How]\nReset dml pointers in new_state to NULL and avoid invalid\npointer\n\n(cherry picked from commit bcafdc61529a48f6f06355d78eb41b3aeda5296c)"

"value": "AV:L - The vulnerable path is reached through the DRM atomic modeset ioctl (`DRM_IOCTL_MODE_ATOMIC`) on `/dev/dri/card*`, requiring local access to the graphics device node. No network or physical-only interface is involved.\nAC:L - The trigger is a `kzalloc` failure of a multi-hundred-KB `struct dml2_context`, a high-order allocation that fails readily under memory pressure/fragmentation the attacker can induce, and the attacker can retry indefinitely with cheap `DRM_MODE_ATOMIC_TEST_ONLY` commits until it hits; once it hits, the dangling pointer persists in the global DM state.\nPR:L - An unprivileged local user with access to the AMD GPU device node (the logged-in seat/console user, a video-group member, or the compositor on Android/kiosk/embedded systems) can hold DRM master and issue atomic commits; no root or capability in the init namespace is needed.\nUI:N - The attacker performs the ioctl and the memory-pressure setup entirely on their own; no victim action is required, and subsequent UAF/double-free is then triggered by the attacker's own further atomic commits.\nS:U - The corruption is confined to kernel heap memory within the same security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - After the erroneous free, `dml21_copy()` memcpys `sizeof(struct dml2_instance)` from a pointer read out of the freed (attacker-reclaimable) `dml2_context`, giving a controlled-source arbitrary kernel read; use-after-free of a large heap object is scored High.\nI:H - The bug yields a double free of the dml2 context plus an arbitrary `kfree()` of a pointer read from freed memory, classic heap-corruption primitives that can be leveraged into arbitrary write and control-flow hijack.\nA:H - The immediate observable effect is a kernel crash — the commit is explicitly titled \"avoid crash\", and the double free / dangling dml2 dereference will oops or panic the machine."
