CVE-2026-45905

CVE-2026-45905 : In the Linux kernel, a race in icmp_route_lookup’s reverse path can cause an ICMP output path to select a LOCAL route due to a faulty call to ip_route_input(). Specifically, during reverse-path handling, ip_route_input() may receive fl4_dec.daddr as destination and return a LOCAL...

Enable Reverse Path Filtering

Setting net.ipv4.conf.all.rpfilter and net.ipv4.conf.default.rpfilter to 1 forces the Linux kernel to perform reverse path filtering on a received packet and check the validity of its source address. If the Linux kernel queries the routing table in which the source address is included and finds...

Linux Bug Opens Most VPNs to Hijacking

A vulnerability in most Linux distros has been uncovered that allows a network-adjacent attacker to hijack VPN connections and inject rogue data into the secure tunnels that victims are using to communicate with remote servers. According to researchers at University of New Mexico and Breakpointin...

New Linux Bug Lets Attackers Hijack Encrypted VPN Connections

A team of cybersecurity researchers has disclosed a new severe vulnerability affecting most Linux and Unix-like operating systems, including FreeBSD, OpenBSD, macOS, iOS, and Android, that could allow remote 'network adjacent attackers' to spy on and tamper with encrypted VPN connections. The...
