Search: CVE-2026-23103

CVE-2026-23103 is a high-severity vulnerability in the Linux kernel's ipvlan implementation. It involves improper locking where the addrs_lock was per ipvlan device rather than per port, leading to potential race conditions and false negatives in address management, particularly affecting IPv6 address handling. The issue is considered minor due to the low likelihood of concurrent calls but can impact confidentiality, integrity, and availability. A fix has been implemented in specific Linux kernel commits.
