CVE-2026-74286

Summary: The CVE-2026-74286 issue affects the Linux kernel PFCP netdevs. The root cause is that PFCP uses dev_get_tstats64() for stats, but pfcp_link_setup() did not request NETDEV_PCPU_STAT_TSTATS, leaving dev->tstats NULL. As a result, creating a PFCP rtnetlink device could prematurely query...

CVE-2026-74286 net: pfcp: allocate per-cpu tstats for PFCP netdevs

In the Linux kernel, the following vulnerability has been resolved: net: pfcp: allocate per-cpu tstats for PFCP netdevs PFCP uses devgettstats64 as its ndogetstats64 callback, but pfcplinksetup does not request NETDEVPCPUSTATTSTATS. The net core therefore leaves dev-tstats NULL for PFCP devices...

CVE-2026-72254

The CVE-2026-72254 entry concerns the Linux kernel netfilter NFT_FIB logic. A fib expression in a netdev egress base chain could dereference nft_in(pkt) on the transmit path, yielding a NULL pointer dereference during eval. The root cause is that nft_fib_validate() masks the hook with NF_INET_* v...
