In the Linux kernel, the following vulnerability has been resolved: net/smc: avoid NULL deref of conn-lnk in smcmsgevent tracepoint The smcmsgevent tracepoint class, shared by smctxsendmsg and smcrxrecvmsg, unconditionally dereferences smc-conn.lnk: stringname, smc-conn.lnk-ibname conn-lnk is onl...

CVE-2026-52940

The CVE-2026-52940 issue affects the Linux kernel tun driver. tun_put_user() allocates an on‑stack virtio_net_hdr_v1_hash_tunnel without zeroing, while virtio_net_hdr_tnl_from_skb() only initializes the first 10 bytes for non‑tunnel SKBs. This allows an unprivileged user to set the vnet header to...
