kernel: net: ipv6: fix NOREF dst use in seg6 and rpl lwtunnels

A flaw was found in the Linux kernel's IPv6 networking implementation, specifically within the seg6 and rpl lwtunnels. A race condition can occur when handling destination cache entries, where a NOREF no reference destination object is used after it has been freed. This use-after-free vulnerabili...

In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: Fixed an invalid unregistererrorpath path. The error path of seg6init is incorrect when the CONFIGIPV6SEG6LWTUNNEL configuration option is not defined. In such cases, if seg6hmacinit fails, the genlunregisterfamily...

CVE-2026-72400

A flaw was found in the Linux kernel's Segment Routing over IPv6 SEG6 component. Insufficient validation of the Segment Routing Header SRH length before reading its fixed fields can lead to an out-of-bounds read. A local attacker, by crafting a malicious BPF Berkeley Packet Filter program, could...
