Vulnerability Details : CVE-2017-17975
Use-after-free in the usbtv_probe function in drivers/media/usb/usbtv/usbtv-core.c in the Linux kernel through 4.14.10 allows attackers to cause a denial of service (system crash) or possibly have unspecified other impact by triggering failure of audio registration, because a kfree of the usbtv data structure occurs during a usbtv_video_free call, but the usbtv_video_fail label's code attempts to both access and free this data structure.

CWE ids for CVE-2017-17975
-
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.Assigned by: nvd@nist.gov (Primary)
