Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: HID: hidraw: fix data race on device refcount The hidraw_open() function increments the hidraw device reference counter. The counter has no dedicated synchronization mechanism, resulting in a potential data race when concurrently opening a device. The race is a regression introduced by commit 8590222e4b02 ("HID: hidraw: Replace hidraw device table mutex with a rwsem"). While minors_rwsem is intended to protect the hidraw_table itself, by instead acquiring the lock for writing, the reference counter is also protected. This is symmetrical to hidraw_release().

No network or physical interaction with the bus is needed to drive the race itself.\nAC:L - The attacker controls both sides of the race \u2014 it is simply two or more threads calling `open()` on the same hidraw node in a loop, retryable indefinitely until the non-atomic `dev-\u003eopen++` loses an update. The race is known to trigger accidentally during normal FIDO2 device probing (systemd issue #27947), and HID hot-unplug/Bluetooth-link-loss events needed to convert the refcount skew into a free are routine and inducible.\nPR:L - An unprivileged local user needs only read access to a hidraw node; systemd\u0027s uaccess/seat udev rules grant the logged-in user an ACL on hidraw devices for FIDO2 tokens, hardware wallets, 3D mice and game controllers (empirically confirmed: `crw-rw----+` with `user:\u003cuid\u003e:rw-`). No capability, no root, no ioctl gate.\nUI:N - The attacker\u0027s own threads perform every step of the attack; no victim action is required. Device detach events occur spontaneously (Bluetooth link loss, dongle removal, uhid teardown) or can be caused by the attacker themselves.\nS:U - The refcount corruption and resulting use-after-free are confined to kernel memory within the same security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - The premature `kfree(struct hidraw)` leaves `list-\u003ehidraw` dangling, and `hidraw_read()` dereferences `list-\u003ehidraw-\u003eexist` and the embedded wait queue on reclaimed memory; a UAF on a small kmalloc object with attacker-sprayed contents yields an arbitrary-read primitive and kernel memory disclosure.\nI:H - `add_wait_queue()`/`remove_wait_queue()` on the freed `hidraw-\u003ewait` write list pointers into reclaimed heap memory, and a sprayed replacement object gives attacker-controlled `list_head` pointers plus a controlled `wait_queue_entry-\u003efunc` call \u2014 an arbitrary write and control-flow hijack. The stale-minor path also corrupts a different, live `struct hidraw`\u0027s refcount.\nA:H - `hidraw_release()` on the orphaned fd dereferences a NULL `hidraw_table[minor]` for a guaranteed oops, and the UAF crashes the kernel outright; additionally the refcount underflow permanently leaks hidraw minors (only 64 exist), denying hidraw registration to all future HID devices."
