In the Linux kernel, the following vulnerability has been resolved:

HID: betop: check shape of output reports

betopff_init() only checks the total sum of the report counts for each report field to be at least 4, but hid_betopff_play() expects 4 report fields. A device advertising an output report with one field and 4 report counts would pass the check but crash the kernel with a NULL pointer dereference in hid_betopff_play().

OESA-2025-1408 — kernel security update

Affected: openEuler:20.03-LTS-SP4: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:

nfc: nci: add flush_workqueue to prevent uaf

Our detector found a concurrent use-after-free bug when detaching an NCI device. The main reason for this bug is the unexpected scheduling between the used delayed mechanism (timer and workqueue).

The race can be demonstrated below:

In short, the cleanup routine thought that the cmd_timer has already been detached by [1] but the mod_timer can re-attach the timer [2], even it is already released [3], resulting in UAF.

This UAF is easy to trigger, crash trace by POC is like below
