Description

An issue was discovered in the Linux kernel before 5.11.11. The netfilter subsystem allows attackers to cause a denial of service (panic) because net/netfilter/x_tables.c and include/linux/netfilter/x_tables.h lack a full memory barrier upon the assignment of a new table value, aka CID-175e476b8cdf.

Affected configurations

• linux linux kernel (< 5.11.11) • fedoraproject fedora 32 • fedoraproject fedora 33 • fedoraproject fedora 34 • debian debian linux 9.0
