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. …
