A race condition in the Linux kernel scheduler can cause a task that is in the SCX_OPSS_DISPATCHING state to be requeued before the dispatch completes. This results in the task’s state being overwritten and the task being dropped from subsequent dispatches, potentially causing erratic scheduling or loss of task execution. The flaw does not expose obvious information disclosure or code execution paths but can degrade system responsiveness.

All Linux kernel installations that include the vulnerable scheduling code. No specific version string is provided, so any kernel prior to the applied fix is affected. Distribution maintainers should examine the kernel release notes for the commit that introduced the fix.

The EPSS score and KEV status are not available, and no public exploits are reported. The CVSS score is not provided in the advisory. The attack vector is likely local or requires elevated privileges to manipulate kernel scheduling behavior. Because the flaw leads to loss of task dispatches, it could be exploited to cause a denial‑of‑service condition but is not currently a high‑impact vulnerability. The risk is moderate until a patched kernel is deployed.
