AI-suggested
A patch is available and should be applied to affected Linux kernel versions. The vendor advisory from Ubuntu confirms that this issue has been fixed in updated kernel releases. Users should update their Linux kernel packages to the fixed versions to mitigate this vulnerability.
Description
A use-after-free (UAF) vulnerability in the Linux kernel's platform/wmi subsystem was resolved by improving locking via the generic driver_override infrastructure. The issue occurred because the bus' match() callback was called without holding the device lock, leading to unsafe access of the driver_override field. This flaw could allow local attackers with limited privileges to cause memory corruption. The vulnerability has a CVSS score of 7.8, indicating high impact on confidentiality, integrity, and availability. Multiple Linux kernel versions are affected, and patches are available.
