CWE-ID:
CWE-416
Exploitation vector: Local
Exploit availability: No
Vulnerable software:
Linux kernel
Operating systems & Components /
Operating system
Vendor: Linux Foundation
Description
The vulnerability allows a local attacker to cause DoS condition on the target system.
The weakness exists in the usbtv_probe function in drivers/media/usb/usbtv/usbtv-core.c due to use-after-free error. A local attacker can trigger 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.
Mitigation
Install update from vendor's website.
Vulnerable software versions
Linux kernel: 4.14 - 4.14.9
