CVE-2026-45905

CVE-2026-45905 is a Linux kernel networking vulnerability in the xfrm/icmp_route_lookup reverse path. The race occurs during ICMP error handling when a concurrent address change may cause ip_route_input() to return a LOCAL route with a dst that can trigger a WARN_ON in ip_rt_bug. The fix checks t...

PT-2026-43772

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A race condition exists in the icmp route lookup function during the reverse path process for sending ICMP error messages with XFRM IPsec policies. When the system acts as a forwarding...

The vulnerability of the icmp_route_lookup() function in the net/ipv4/icmp.c module of the IPv4 protocol implementation in the Linux operating system allows a attacker to cause a service failure.

The vulnerability of the icmproutelookup function in the net/ipv4/icmp.c module of the IPv4 protocol implementation in the Linux operating system is related to the execution of a loop with an unreachable exit condition. Exploiting this vulnerability could allow a attacker to cause a service failu...

kernel: net: Fix icmp host relookup triggering ip_rt_bug

A denial of service vulnerability was found in the Linux kernel. icmproutelookup creates input routes for locally generated packets during xfrm relookup ICMP traffic. Then it will set the input route dst-out = iprtbug to skb for DESTUNREACH, leading to loss of availability of the system...
