**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 5.15.14-1.fc32.qubes.x86 64 **Description** A kernel crash issue has been identified in the Linux kernel, specifically in the mt7921 driver. The crash occurs when the `mt7921 irq handler` function is called while `devm free irq` is being handled, causing a NULL pointer dereference. This issue is related to the premature freeing of the mt76 device. A crash log has been provided, showing a kernel NULL pointer dereference error. **Recommendations** To resolve this issue, update the Linux kernel to a version that includes the fix for the mt7921 driver. As a temporary workaround, consider disabling the `mt7921 irq handler` function until a patch is available. Restrict access to the vulnerable mt76 device to minimize the risk of exploitation. Avoid using the `devm free irq` function in conjunction with the `mt7921 irq handler` function until the issue is resolved.
