Description OSIDB Bzimport 2025-02-27 03:04:39 UTC 
In the Linux kernel, the following vulnerability has been resolved:

media: uvcvideo: Fix double free in error path

If the uvc_status_init() function fails to allocate the int_urb, it will
free the dev->status pointer but doesn't reset the pointer to NULL. This
results in the kfree() call in uvc_status_cleanup() trying to
double-free the memory. Fix it by resetting the dev->status pointer to
NULL after freeing it.
