CVE-2026-64025

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter sockmap component when used with kernel TLS kTLS receive. A race condition exists where skpsockverdictdataready can improperly interact with the kTLS receive process. This can lead to a use-after-free vulnerability, potentially...

CVE-2026-63926

A flaw was found in the Linux kernel's sockmap feature. When the bpfmsgpushdata function processes data, it incorrectly calculates the offset for data fragments, leading to an inconsistent memory arrangement. This issue could potentially allow a local attacker to cause data corruption or system...

In the Linux kernel, the following vulnerability has been resolved: bpf, skmsg: fix verdict skdataready racing with ktls rx skpsockstrpdataready already checks tlsswhasctxrx and defers to psock-saveddataready when a TLS RX context is present, avoiding a conflict with the TLS strparser's ownership...

Linux Distros Unpatched Vulnerability : CVE-2026-63926

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - bpf: sockmap: fix tail fragment offset in bpfmsgpushdata When bpfmsgpushdata inserts data in the middle of a scatterlist entry, it splits the original entry int...

CVE-2026-63926

In the Linux kernel, the following vulnerability has been resolved: bpf: sockmap: fix tail fragment offset in bpfmsgpushdata When bpfmsgpushdata inserts data in the middle of a scatterlist entry, it splits the original entry into a left fragment and a right fragment. The right fragment offset is...

CVE-2026-63926

CVE-2026-63926 affects the Linux kernel where the bpf sockmap data path (bpf_msg_push_data) mishandles the tail fragment offset when inserting data into a scatterlist. The issue occurs when splitting a scatterlist entry into left/right fragments; the right fragment offset was advanced using a mes...

SUSE CVE-2026-53033

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Take state lock for afunix iter When a BPF iterator program updates a sockmap, there is a race condition in unixstreambpfupdateproto where the peer pointer can become stale1 during a state transition TCPESTABLISHED ...

CVE-2026-53035

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF sockmap component. A deadlock can occur in the bpfiterunixseqshow function when an iterator program attempts to update a sockmap while a lock is already held. This recursive locking scenario can lead to a system freeze or...

SUSE CVE-2026-53005

In the Linux kernel, the following vulnerability has been resolved: afunix: Drop all SCM attributes for SOCKMAP. SOCKMAP can hide inflight fd from AFUNIX GC. When a socket in SOCKMAP receives skb with inflight fd, skpsockverdictdataready looks up the mapped socket and enqueue skb to its...

CVE-2026-53184

A flaw was found in the Linux kernel. When a User Datagram Protocol UDP socket is configured with a sockmap, and a BPF Berkeley Packet Filter program attached to it calls a socket-lookup helper, the skb-dev field is not properly cleared. This improper handling of the skb-dev field can lead to a...

CVE-2026-53034

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF and sockmap components, specifically within the afunix socket operations. A race condition occurs during the connection process where a socket's state is updated before its peer is fully assigned. This timing issue can lead to a...

CVE-2026-53033

A flaw was found in the Linux kernel's sockmap functionality. A race condition exists in the unixstreambpfupdateproto function when a BPF Berkeley Packet Filter iterator program updates a sockmap.
