Overview
CVE-2022-50764 is a known-severity vulnerability. It was published on December 24, 2025.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
ipv6/sit: use DEV_STATS_INC() to avoid data-races
syzbot/KCSAN reported that multiple cpus are updating dev->stats.tx_error
concurrently.
This is because sit tunnels are NETIF_F_LLTX, meaning their ndo_start_xmit()
is not protected by a spinlock.
While original KCSAN report was about tx path, rx path has the same issue.
