CVE-2026-63923

CVE-2026-63923 affects the Linux kernel’s octeontx2-af path, where rvu_mbox_handler_rep_event_notify forwards attacker-controlled event fields (pcifunc) without proper bounds checking. The root cause is lack of validation when translating nested body pcifunc into PF/VF mailbox indices, allowing o...

CVE-2026-63921

CVE-2026-63921 affects the Linux kernel’s IPv6 VTI (ip6: vti) implementation. The root cause is a collision-lookup using dev_net(dev) in vti6_siocdevprivate(), which, after tunnels migrate between namespaces, can cause SIOCCHGTUNNEL to resolve against the wrong netns. This enables a scenario wher...

CVE-2026-63921

In the Linux kernel, the following vulnerability has been resolved: ip6: vti: Use ip6tnl.net in vti6siocdevprivate. After patch 1/2 in this series, vti6update unlinks and relinks the tunnel through t-net. vti6siocdevprivate still uses devnetdev for the collision lookup. For a tunnel moved through...

CVE-2026-63920

The CVE-2026-63920 entry describes a Linux kernel vulnerability in IPv6 extension header handling. The issue arises when ip6_datagram_recv_specific_ctl() builds IPV6_…cmsgs by trusting on-wire hdrlen (ptr[1]) during put_cmsg() length calculation. Although the write to hdrlen is in-bounds, reading...

In the Linux kernel, the following vulnerability has been resolved: nfc: hci: fix out-of-bounds read in HCP header parsing Both nfchcirecvfromllc and ncihcidatareceivedcb read packet-header from skb-data at function entry without first checking that the buffer holds at least one byte. A malicious...

EUVD-2026-45686

In the Linux kernel, the following vulnerability has been resolved: netfilter: conntrack: tcp: do not force CLOSE on invalid-seq RST without direction check An unintended behavior in the TCP conntrack state machine allows a connection to be forced into the CLOSE state using an RST packet with an...

CVE-2026-63913

The CVE-2026-63913 entry concerns the Linux kernel netfilter conntrack TCP state machine. A crafted RST with an invalid SEQ after observing a SYN could transition the conntrack entry to TCP_CONNTRACK_CLOSE, even if the RST is not a valid response to the observed SYN or its direction. This could p...
