CVE-2025-71080

CVE-2025-71080 concerns a race in Linux kernel IPv6 PREEMPT_RT code. On PREEMPT_RT kernels, after rt6_get_pcpu_route() returns NULL, a preemption can allow another task on the same CPU to install a pcpu_rt entry; when the first task resumes, the cmpxchg() in rt6_make_pcpu_route() may fail and tri...

CVE-2025-68813

The CVE-2025-68813 affects the Linux kernel IPVS IPv4 route error path. A NULL pointer dereference occurs when dst_link_failure() is called with skb->dev unset, leading to ipv4_link_failure() → ipv4_send_dest_unreach() → fib_compute_spec_dst() dereferencing skb->dev. The root cause is that ...
