Linux kernel Vicam USB driver denial of service
| linux-vicam-dos (15246) |  Low Risk |
Description:
Linux kernel is vulnerable to a denial of service. The copy_from_user() function is not used to access userspace, which crosses security boundaries. A local attacker could exploit this vulnerability to possibly cause a denial of service.
