AI-suggested
The vulnerability description indicates a fix has been implemented in the Linux kernel by adopting the generic driver_override infrastructure, which properly handles locking. Users should monitor official Linux kernel advisories and update to fixed kernel versions once available.
Description
A use-after-free (UAF) vulnerability in the Linux kernel's PCI driver probing mechanism was resolved by adopting the generic driver_override infrastructure. The issue arises because the bus match() callback is called without holding the device lock, leading to unsafe access to the driver_override field. This vulnerability could allow an attacker with local privileges to cause high impact on confidentiality, integrity, and availability. The fix involves proper locking handled internally by the driver-core infrastructure.
