Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.2

Description The issue is related to the virtnet probe function in the Linux kernel, which fails to properly allocate memory when supporting the FRAGLIST feature. This allows guest OS users to cause a denial of service by sending a crafted sequence of fragmented packets, resulting in a buffer overflow and memory corruption.

Recommendations For Linux kernel versions prior to 4.2, update to version 4.2 or later to resolve the issue.
