Description
This security bulletin contains information about 1 security vulnerability.
1) Race condition (CVE-ID: CVE-2026-23469)
The vulnerability allows a local attacker to cause a denial of service.
The vulnerability exists due to a race condition in the drm/imagination GPU driver interrupt handling during runtime power management suspend when suspending the GPU while an IRQ handler is still running on another CPU core. A local attacker can trigger GPU activity that races with runtime suspend to cause a denial of service.
This issue can lead to kernel crashes or a kernel panic when the IRQ handler accesses GPU registers while the GPU is suspended.
