NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-base package and not the kernel-rt-base package as distributed by SLES.

An issue was discovered in the Linux kernel before 5.6.7. xdp_umem_reg in net/xdp/xdp_umem.c has an out-of-bounds write (by a user with the CAP_NET_ADMIN capability) because of a lack of headroom validation.
