Description
This security bulletin contains information about 1 vulnerability.
1) Use-after-free (CVE-ID: CVE-2026-68361)
CWE-ID: CWE-416 - Use After Free
CVSSv4: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to execute arbitrary code.
The vulnerability exists due to a use-after-free in corsairpsu_probe() and HID input report handling when stopping a device after probe failure while input reports are still being processed. A local user can trigger the race condition during device initialization failure to execute arbitrary code.
The issue is triggered by a race condition between hid_input_report() and the code path immediately following hid_device_io_start() during probe failure.
