Description
This security bulletin contains information about 1 vulnerability.
1) Use-after-free (CVE-ID: CVE-2026-68360)
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 the corsair-cpro driver probe function when handling device I/O during probe failure after I/O start. A local user can trigger the vulnerable code path to execute arbitrary code.
The issue is caused by a race condition between hid_input_report() and execution immediately following hid_device_io_start() during probing.
Remediation
Install update from vendor's website.
