CVE-2023-39192

Name of the Vulnerable Software and Affected Versions Linux Kernel (affected versions not specified)

Description The issue is related to a flaw in the Netfilter subsystem of the Linux kernel, specifically in the xt u32 module, which does not validate fields in the xt u32 structure.

The flaw is associated with the u32 match it function and involves reading data beyond buffer boundaries in memory.
