Description
This security bulletin contains information about 1 vulnerability.
1) Race condition (CVE-ID: CVE-2026-68317)
CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to a race condition and NULL pointer dereference in the pds_core auxiliary device add and delete logic when concurrent add or delete operations access the same auxiliary device slot. A local user can trigger concurrent device add or delete operations to cause a denial of service.
The issue arises because the shared slot is not consistently checked and updated under config_lock in both paths.
Remediation
Install update from vendor's website.
