A vulnerability has been reported in the Linux kernel, which can be exploited by malicious, local users to cause a DoS (Denial of Service).
The vulnerability is caused due to the Vicam USB driver dereferencing userspace pointers directly instead of using the "copy_from_user()" function when accessing userspace. This violates security boundaries and can result in a DoS when copying data from user to kernel space.
The vulnerability reportedly affects kernel versions prior to 2.4.25 and 2.6.6.
Solution: The vulnerability has been addressed in versions 2.4.25 and 2.6.6.
