DescriptionNVD

In the Linux kernel, the following vulnerability has been resolved:

driver core: platform: use generic driver_override infrastructure

When a driver is probed through __driver_attach(), the bus' match() callback is called without the device lock held, thus accessing the driver_override field without a lock, which can cause a UAF.

Fix this by using the driver-core driver_override infrastructure taking care of proper locking internally.

Note that calling match() from __driver_attach() without the device lock held is intentional. [1]

AnalysisAI

Use-after-free in Linux Kernel platform driver core allows local authenticated attackers to achieve high-severity impacts including code execution, privilege escalation, or denial of service. The vulnerability stems from unsafe access to the driver_override field during device probing when the bus match() callback executes without device lock protection. …

RemediationAI

Within 24 hours: inventory all systems running Linux kernel versions prior to 6.12.80, 6.18.21, 6.19.11, or 7.0, and identify those with local user access. Within 7 days: test kernel updates 6.12.80, 6.18.21, 6.19.11, or 7.0 (depending on current branch) in non-production environments. …
