CWE-416
Bugzilla:
1402885: CVE-2016-7913 kernel: media: use-after-free in [tuner-xc2028] media driver
The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel before 4.6 allows local users to gain privileges or cause a denial of service (use-after-free) via vectors involving omission of the firmware name from a certain data structure. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.
