"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbinder: fix freeze UAF in binder_release_work()\n\nWhen a binder reference is cleaned up, any freeze work queued in the\nassociated process should also be removed. Otherwise, the reference is\nfreed while its ref->freeze.work is still queued in proc->work leading\nto a use-after-free issue as shown by the following KASAN report:\n\n ==================================================================\n BUG: KASAN: slab-use-after-free in binder_release_work+0x398/0x3d0\n Read of size 8 at addr ffff31600ee91488 by task kworker/5:1/211\n\n CPU: 5 UID: 0 PID: 211 Comm: kworker/5:1 Not tainted 6.11.0-rc7-00382-gfc6c92196396 #22\n Hardware name: linux,dummy-virt (DT)\n Workqueue: events binder_deferred_func\n Call trace:\n binder_release_work+0x398/0x3d0\n binder_deferred_func+0xb60/0x109c\n process_one_work+0x51c/0xbd4\n worker_thread+0x608/0xee8\n\n Allocated by task 703:\n __kmalloc_cache_noprof+0x130/0x280\n binder_thread_write+0xdb4/0x42a0\n binder_ioctl+0x18f0/0x25ac\n __arm64_sys_ioctl+0x124/0x190\n invoke_syscall+0x6c/0x254\n\n Freed by task 211:\n kfree+0xc4/0x230\n binder_deferred_func+0xae8/0x109c\n process_one_work+0x51c/0xbd4\n worker_thread+0x608/0xee8\n ==================================================================\n\nThis commit fixes the issue by ensuring any queued freeze work is removed\nwhen cleaning up a binder reference."

"value": "AV:L - The vulnerability is reached only through ioctl(BINDER_WRITE_READ) on the local /dev/binder device file; there is no network-facing path, so the attacker needs local system access.\nAC:L - This is a missing-dequeue logic error where the attacker fully controls both the freeze-notification registration and the ref teardown, allowing the freed-while-queued condition to be set up reliably without winning any uncontrollable race.\nPR:L - Triggering requires only opening the binder device and issuing standard binder commands, which any unprivileged local app can do on Android; no elevated capability gates the freeze-notification path.\nUI:N - The attacking process performs the registration, ref drop, and work processing itself; no action from any other user is required.\nS:U - The use-after-free is confined to kernel memory within the same security authority; exploitation yields standard local kernel compromise without crossing a VM/IOMMU boundary.\nC:H - The freed binder_ref_freeze object can be reallocated with attacker-controlled data before the stale pointer is read in binder_release_work(), enabling disclosure of kernel memory.\nI:H - The freed object remains linked on proc->todo and is manipulated as list-work after reallocation, so heap spraying of the reclaimed slot provides a write/control-flow primitive typical of exploitable UAFs.\nA:H - The use-after-free reliably corrupts kernel state and causes an oops/panic, producing a kernel crash and denial of service."
