Kernel: xfrm: out-of-bounds read in __xfrm_state_filter_match()

Published: 10/9/2023 Last updated: 11/6/2025 Reserved: 7/25/2023

A flaw was found in the XFRM subsystem in the Linux kernel. The specific flaw exists within the processing of state filters, which can result in a read past the end of an allocated buffer. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, potentially leading to an information disclosure.
