CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The issue is related to an integer overflow in the xp create and assign umem() function. This occurs because the product of the i and pool->chunk size variables, both of type u32, can wrap around and then be cast to u64. As a result, two different XDP buffers can point to the same memory area.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
