Summary
A data race on the death_list in the Linux kernel's Rust Binder driver was found. An unsafe remove operation can run concurrently with moving items to a local list, corrupting prev/next pointers and causing system crashes.
Risk Assessment
This vulnerability can cause kernel panics in systems using Rust Binder, leading to service disruption and potential data loss.
Recommendation
Apply the patch from the Linux kernel repository immediately, which modifies Node::release to pop items directly from the original list, eliminating the race condition.
Other vulnerabilities in Linux kernel
See all- CVE-2026-80577Unknown
In the Linux kernel's drm/panthor driver, panthor_fw_load_section_entry() skips BO creation for zero-sized firmware sections but adds them to the section list, leading to NULL pointer dereference in later paths. The fix skips adding such sections to the list.
- CVE-2026-80571Unknown
In the Linux kernel powerpc/pseries papr-phy-attest, missing validation of cmd.length could lead to buffer overflow. The fix adds length checks and fixes memory leaks on error paths.
- CVE-2026-80567Unknown
In the Linux kernel Synaptics RMI4 driver (F54), worker errors were not propagated to the V4L2 queue, causing stale or uninitialized data to be delivered to userspace. The fix adds error checking and marks buffers as error state.
- CVE-2026-80566Unknown
In the Linux kernel, the hynitron_cstxxx driver improperly validated touch count and finger IDs. This can lead to corrupted touch state or out-of-bounds buffer access.
- CVE-2026-80564Unknown
In the Linux kernel, the gve driver lacks an implementation of adjfine, leading to a NULL pointer dereference when triggered from userspace, e.g., via testptp.
- CVE-2026-80563Unknown
A use-after-free vulnerability was found in the Linux kernel's gpio-sloppy-logic-analyzer driver. The 'trigger' debugfs file lacked proper protection, allowing a write to freed memory during device unbind. The issue was fixed by using debugfs_create_file() instead of debugfs_create_file_unsafe().
- CVE-2026-80543Unknown
In the Linux kernel, the xcrb_msg_to_type6cprb_msgx() and xcrb_msg_to_type6_ep11cprb_msgx() functions for s390/zcrypt copy a user space message into a kernel buffer based on length, but further processing assumes 4-byte alignment. As a result, up to 3 bytes of uninitialized kernel memory are forwarded to further processing, potentially exposing kernel memory to the crypto card firmware.
- CVE-2026-80542Unknown
In the Linux kernel, the amdgpu driver for AMD Display has a NULL pointer dereference in amdgpu_dm_crtc_set_vblank() when vblank is enabled or queried before a stream is attached to acrtc_state->stream. This can lead to a system crash.
- CVE-2026-80535Unknown
In the Linux kernel XFS filesystem, during directory tree repair, a self-referential directory may be detected. In such a case, the repair code attempts to lock the same inode twice (double iolock/ilock), leading to a deadlock. The fix detects this corner case and handles it appropriately.
- CVE-2026-80533Unknown
In the Linux kernel XFS filesystem, during AGI repair, the function xrep_iunlink_walk_ondisk_bucket may attempt to use the pointer sc->sa.agi_bp, which can be null if the buffer verifier fails. The fix uses ragi->agi_bp instead, which skips verifier checks, to avoid walking off the end of memory.
Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: rust_binder: fix race condition on death_list Rust Binder contains the following unsafe operation: // SAFETY: A `NodeDeath` is never inserted into the death list // of any node other than its owner, so it is either in this // death list or in no death list. unsafe { node_inner.death_list.remove(self) }; This operation is unsafe because when touching the prev/next pointers of a list element, we have to ensure that no other thread is also touching them in parallel. If the node is present in the list that `remove` is called on, then that is fine because we have exclusive access to that list. If the node is not in any list, then it's also ok. But if it's present in a different list that may be accessed in parallel, then that may be a data race on the prev/next pointers. And unfortunately that is exactly what is happening here. In Node::release, we: 1. Take the lock. 2. Move all items to a local list on the stack. 3. Drop the lock. 4. Iterate the local list on the stack. Combined with threads using the unsafe remove method on the original list, this leads to memory corruption of the prev/next pointers. This leads to crashes like this one: Unable to handle kernel paging request at virtual address 000bb9841bcac70e Mem abort info: ESR = 0x0000000096000044 EC = 0x25: DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 FSC = 0x04: level 0 translation fault Data abort info: ISV = 0, ISS = 0x00000044, ISS2 = 0x00000000 CM = 0, WnR = 1, TnD = 0, TagAccess = 0 GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0 [000bb9841bcac70e] address between user and kernel address ranges Internal error: Oops: 0000000096000044 [#1] PREEMPT SMP google-cdd 538c004.gcdd: context saved(CPU:1) item - log_kevents is disabled Modules linked in: ... rust_binder CPU: 1 UID: 0 PID: 2092 Comm: kworker/1:178 Tainted: G S W OE 6.12.52-android16-5-g98debd5df505-4k #1 f94a6367396c5488d635708e43ee0c888d230b0b Tainted: [S]=CPU_OUT_OF_SPEC, [W]=WARN, [O]=OOT_MODULE, [E]=UNSIGNED_MODULE Hardware name: MUSTANG PVT 1.0 based on LGA (DT) Workqueue: events _RNvXs6_NtCsdfZWD8DztAw_6kernel9workqueueINtNtNtB7_4sync3arc3ArcNtNtCs8QPsHWIn21X_16rust_binder_main7process7ProcessEINtB5_15WorkItemPointerKy0_E3runB13_ [rust_binder] pstate: 23400005 (nzCv daif +PAN -UAO +TCO +DIT -SSBS BTYPE=--) pc : _RNvXs3_NtCs8QPsHWIn21X_16rust_binder_main7processNtB5_7ProcessNtNtCsdfZWD8DztAw_6kernel9workqueue8WorkItem3run+0x450/0x11f8 [rust_binder] lr : _RNvXs3_NtCs8QPsHWIn21X_16rust_binder_main7processNtB5_7ProcessNtNtCsdfZWD8DztAw_6kernel9workqueue8WorkItem3run+0x464/0x11f8 [rust_binder] sp : ffffffc09b433ac0 x29: ffffffc09b433d30 x28: ffffff8821690000 x27: ffffffd40cbaa448 x26: ffffff8821690000 x25: 00000000ffffffff x24: ffffff88d0376578 x23: 0000000000000001 x22: ffffffc09b433c78 x21: ffffff88e8f9bf40 x20: ffffff88e8f9bf40 x19: ffffff882692b000 x18: ffffffd40f10bf00 x17: 00000000c006287d x16: 00000000c006287d x15: 00000000000003b0 x14: 0000000000000100 x13: 000000201cb79ae0 x12: fffffffffffffff0 x11: 0000000000000000 x10: 0000000000000001 x9 : 0000000000000000 x8 : b80bb9841bcac706 x7 : 0000000000000001 x6 : fffffffebee63f30 x5 : 0000000000000000 x4 : 0000000000000001 x3 : 0000000000000000 x2 : 0000000000004c31 x1 : ffffff88216900c0 x0 : ffffff88e8f9bf00 Call trace: _RNvXs3_NtCs8QPsHWIn21X_16rust_binder_main7processNtB5_7ProcessNtNtCsdfZWD8DztAw_6kernel9workqueue8WorkItem3run+0x450/0x11f8 [rust_binder bbc172b53665bbc815363b22e97e3f7e3fe971fc] process_scheduled_works+0x1c4/0x45c worker_thread+0x32c/0x3e8 kthread+0x11c/0x1c8 ret_from_fork+0x10/0x20 Code: 94218d85 b4000155 a94026a8 d10102a0 (f9000509) ---[ end trace 0000000000000000 ]--- Thus, modify Node::release to pop items directly off the original list.
