CVE-2026-74286

In the Linux kernel, the following vulnerability has been resolved:

net: pfcp: allocate per-cpu tstats for PFCP netdevs

PFCP uses dev_get_tstats64() as its ndo_get_stats64 callback, but

pfcp_link_setup() does not request NETDEV_PCPU_STAT_TSTATS. The net

core therefore leaves dev->tstats NULL for PFCP devices.

Creating a PFCP rtnetlink device can immediately ask the new netdev for

stats while building the RTM_NEWLINK notification. That reaches

dev_get_tstats64() and dereferences the NULL dev->tstats pointer.

Set pcpu_stat_type to NETDEV_PCPU_STAT_TSTATS during PFCP link setup so

the net core allocates the storage expected by dev_get_tstats64().
