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-2026-53223

CVE-2026-53223 (Linux kernel) resolves an issue in the net layer where skb_is_err_queue() treated PACKET_OUTGOING as the sole marker for error-queue skbs. This misclassification does not hold for AF_PACKET sockets, where outgoing taps can also be delivered to packet sockets with skb->pkt_type ...

CVE-2026-52928

A flaw was found in the Linux kernel's afunix component. This vulnerability involves the incorrect handling of the SIOCATMARK operation when used with non-stream sockets, such as SOCKDGRAM and SOCKSEQPACKET. These socket types did not properly reject SIOCATMARK, an operation intended only for...

EUVD-2026-38901

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 ...

EUVD-2026-38873

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...

EUVD-2026-38862

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: fix MSGZEROCOPY pinned-pages accounting virtiotransportinitzcopyskb uses iter-count as the size argument for msgzerocopyrealloc, which in turn passes it to mmaccountpinnedpages for RLIMITMEMLOCK accounting. However,...

EUVD-2026-38945

In the Linux kernel, the following vulnerability has been resolved: net/rds: Restrict use of RDS/IB to the initial network namespace Prevent using RDS/IB in network namespaces other than the initial one. The existing RDS/IB code will not work properly in non-initial network namespaces...

CVE-2026-52939

A flaw was found in the Linux kernel's Reliable Datagram Sockets RDS component. An unprivileged local user can trigger a kernel panic by sending a specially crafted atomic control message cmsg over an active RDS/InfiniBand IB connection. This issue is caused by improper handling of masked atomic...

UBUNTU-CVE-2026-52928

In the Linux kernel, the following vulnerability has been resolved: afunix: Reject SIOCATMARK on non-stream sockets SIOCATMARK reports whether the receive queue is at the urgent mark for MSGOOB. In AFUNIX, MSGOOB is supported only for SOCKSTREAM sockets. SOCKDGRAM and SOCKSEQPACKET reject MSGOOB ...

EUVD-2026-38698

In the Linux kernel, the following vulnerability has been resolved: afunix: Reject SIOCATMARK on non-stream sockets SIOCATMARK reports whether the receive queue is at the urgent mark for MSGOOB. In AFUNIX, MSGOOB is supported only for SOCKSTREAM sockets. SOCKDGRAM and SOCKSEQPACKET reject MSGOOB ...

CVE-2026-52928

The CVE-2026-52928 entry concerns the Linux kernel’s AF_UNIX handling of SIOCATMARK, where MSG_OOB is valid only on SOCK_STREAM. The root cause is that SIOCATMARK was evaluated against the receive queue on non-stream sockets; the fix ensures non-stream sockets return -EOPNOTSUPP before inspecting...

CVE-2026-49860

Deno is a JavaScript, TypeScript, and WebAssembly runtime. Prior to 2.8.1, when a WebSocket connection was opened, Deno checked the destination hostname against --deny-net rules but did not re-check the IP addresses that hostname resolved to. An attacker-controlled script could use a specially...

CVE-2026-47139

A flaw was found in vm2, a Node.js sandbox. This vulnerability allows sandboxed code to bypass network restrictions by utilizing internal HTTP built-ins, such as httpclient and httpserver. An attacker can exploit this to make outbound HTTP requests or open listening HTTP sockets, even when public...

Ubuntu 20.04 LTS : Linux kernel (Oracle) vulnerabilities (USN-8462-1)

The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8462-1 advisory. It was discovered that the Linux kernel algifaead module did not properly handle in-place cryptographic operations. This flaw is known as Copy Fail. A...

kernel: Linux kernel: Use-After-Free in net/gro due to improper handling of zerocopy skbs

A flaw was found in the Linux kernel's Generic Receive Offload GRO networking subsystem. This vulnerability occurs when skbgroreceive attempts to merge zerocopy socket buffers skbs without properly managing page reference counts, specifically when the SKBFLMANAGEDFRAGREFS flag is set. An attacker...
