What is CVE-2026-45980?

Official description
In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Stop job scheduling across aie2_release_resource()
Running jobs on a hardware context while it is in the process of releasing resources can lead to use-after-free and crashes.
Fix this by stopping job scheduling before calling aie2_release_resource() and restarting it after the release completes. Additionally, aie2_sched_job_run() now checks whether the hardware context is still active.
Weakness: CWE-416
