Pending analysis
Type:
CWE-476 NULL Pointer Dereference
Publication date:

Last modified:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> driver core: fix potential NULL pointer dereference in dev_uevent()<br /> <br /> If userspace reads "uevent" device attribute at the same time as another<br /> threads unbinds the device from its driver, change to dev-&gt;driver from a<br /> valid pointer to NULL may result in crash. Fix this by using READ_ONCE()<br /> when fetching the pointer, and take bus&amp;#39; drivers klist lock to make sure<br /> driver instance will not disappear while we access it.<br /> <br /> Use WRITE_ONCE() when setting the driver pointer to ensure there is no<br /> tearing.
