Description

In the Linux kernel, the following vulnerability has been resolved: driver core: fix potential NULL pointer dereference in dev_uevent() If userspace reads "uevent" device attribute at the same time as another threads unbinds the device from its driver, change to dev->driver from a valid pointer to NULL may result in crash. Fix this by using READ_ONCE() when fetching the pointer, and take bus' drivers klist lock to make sure driver instance will not disappear while we access it. Use WRITE_ONCE() when setting the driver pointer to ensure there is no tearing.

Affected configurations

• linux linux kernel (< 6.6.89) • linux linux kernel (>= 6.7 < 6.12.26) • linux linux kernel (>= 6.13 < 6.14.5) • linux linux kernel 6.15
