EUVD-2025-124925

In the Linux kernel, the following vulnerability has been resolved: ipv6: use RCU in ip6output Use RCU in ip6output in order to use dstdevrcu to prevent possible UAF. We can remove rcureadlock/rcureadunlock pairs from ip6finishoutput2...

CVE-2025-40158

CVE-2025-40158 is a Linux kernel vulnerability affecting IPv6 handling. The issue is addressed by using RCU in ip6_output() to safely access dst_dev_rcu() and by removing rcu_read_lock()/rcu_read_unlock() from ip6_finish_output2(), preventing use-after-free scenarios. The fixes are reflected in m...
