CVE-2026-64016

CVE-2026-64016 : In the Linux kernel, the ksmbd durable reconnect path could mismanage file objects when a later error path occurred after a successful durable reconnect. Specifically, ksmbd_reopen_durable_fd() republished the same ksmbd_file into the session volatile-id table, and if smb2_open()...

In the Linux kernel, the following vulnerability has been resolved: nfc: llcp: Fix use-after-free race in nfcllcprecvcc A race condition exists in the NFC LLCP connection state machine where the connection acceptance packet CC can be processed concurrently with socket release. This can lead to a...

CVE-2026-63994 tunnels: load network headers after skb_cow() in iptunnel_pmtud_build_icmp[v6]()

In the Linux kernel, the following vulnerability has been resolved: tunnels: load network headers after skbcow in iptunnelpmtudbuildicmpv6 Sashiko found that iptunnelpmtudbuildicmp and iptunnelpmtudbuildicmpv6 were caching iphdr and ipv6hdr before an skbcow call which can reallocate skb-head. Fix...

CVE-2026-63993 vxlan: do not reuse cached ip_hdr() value after skb_tunnel_check_pmtu()

In the Linux kernel, the following vulnerability has been resolved: vxlan: do not reuse cached iphdr value after skbtunnelcheckpmtu skbtunnelcheckpmtu can change skb-head. Reusing oldiph afer skbtunnelcheckpmtu can cause an UAF. Use instead iphdrskb as done in drivers/net/bareudp.c and...

CVE-2026-63993

CVE-2026-63993 corresponds to a Linux kernel issue in VXLAN handling: skb_tunnel_check_pmtu() may modify skb->head, causing a stale ip_hdr() reference to be reused and potentially leading to use-after-free (UAF). The advised remediation is to use ip_hdr(skb) instead of the cached value, as imp...

CVE-2026-63994 tunnels: load network headers after skb_cow() in iptunnel_pmtud_build_icmp[v6]()

In the Linux kernel, the following vulnerability has been resolved: tunnels: load network headers after skbcow in iptunnelpmtudbuildicmpv6 Sashiko found that iptunnelpmtudbuildicmp and iptunnelpmtudbuildicmpv6 were caching iphdr and ipv6hdr before an skbcow call which can reallocate skb-head. Fix...

CVE-2026-63992 tunnels: do not assume transport header in iptunnel_pmtud_check_icmp()

In the Linux kernel, the following vulnerability has been resolved: tunnels: do not assume transport header in iptunnelpmtudcheckicmp In some cases, iptunnelpmtudcheckicmp can be called while skb transport header is not set. This triggers an out-of-bound access, because typeofskb-transportheader0...

CVE-2026-63989

In the Linux kernel, the following vulnerability has been resolved: bridge: Fix sleep in atomic context in netlink path Since the introduction of the netlink configuration path for bridge ports in commit 25c71c75ac87 "bridge: bridge port parameters over netlink", brsetport was always called with...

CVE-2026-63989

CVE-2026-63989 concerns the Linux kernel bridge netlink path. The issue arises because br_setport() was historically called with the bridge lock held, but br_setport processes many attributes (flags, FDB flushing, multicast, group forward mask, backup port/NHID) that do not require the bridge loc...

CVE-2026-63988

CVE-2026-63988 concerns a Linux kernel fix for sleeping in atomic context during sysfs path handling in bridge brport_store(). The root cause: brport_store() previously held the bridge lock for many attributes; now most attributes don’t require the lock. As a result, calling dev_set_promiscuity()...

EUVD-2026-45561

In the Linux kernel, the following vulnerability has been resolved: bridge: Fix sleep in atomic context in sysfs path Since the start of the git history, brportstore always acquired the bridge lock. Back then this decision made sense: The bridge lock protects the STP state of the bridge and its...
