**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to a NULL pointer dereference in the `amdgpu fence driver sw fini()` function, which can cause a denial of service. The problem occurs when the `drm sched fini()` function is called without its counterpart `drm sched init()` being executed successfully. This can happen during a driver probe failure, as seen in the Steam Deck. To prevent this, a check is added to ensure the `drm sched` is properly initialized for a given ring before calling its fini counter-part. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A potential crash issue in the Linux kernel has been resolved. The vmbus driver, which can be built as a module, relies on the panic notifier infrastructure to perform certain operations when a panic event is detected. However, the panic notifier registration was done unconditionally in the module initialization routine, while the unregistering procedure was conditionally guarded and only executed if a specific capability was set. This issue has been fixed by unconditionally unregistering the panic notifier in the module's exit routine. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
