CVE-2026-53005

A flaw was found in the Linux kernel's afunix component, specifically within its SOCKMAP feature. This vulnerability stems from the kernel's improper handling of Socket Control Message SCM attributes when data is passed to the SOCKMAP layer. This can lead to a use-after-free condition, which may...

EUVD-2026-39348

An attacker might be able to cause outgoing TCP connections to backend to be stuck until a timeout occurs instead of being released immediately, by sending IXFR queries. This could be used to cause a denial of service if there is a limit to the number of concurrent connections to this backend, or...

CVE-2026-52814

Gogs is an open source self-hosted Git service. Prior to 0.14.3, the Gogs built-in Go SSH server is vulnerable to an unauthenticated, asymmetric Denial of Service DoS attack. The application accepts inbound TCP connections and passes them to golang.org/x/crypto/ssh.NewServerConn inside a new...

CVE-2026-13201

A flaw was found in KubeVirt's safepath package used by virt-handler. The OpenAtNoFollow function uses OPATH|ONOFOLLOW to obtain a file descriptor to a path leaf, but downstream operations resolve the path via /proc/self/fd/N using link-following syscalls. When the leaf is a symlink, the kernel...

CVE-2026-13201

CVE-2026-13201 concerns KubeVirt’s safepath package, where OpenAtNoFollow uses O_PATH|O_NOFOLLOW to obtain a descriptor for a path leaf, but downstream helpers access paths via /proc/self/fd/N. If the leaf is a symlink, the kernel dereferences it, bypassing intended no-follow protection. An attac...

CVE-2026-52814 Gogs: Unauthenticated Asymmetric Denial of Service (DoS) via SSH Handshake Stall (File Descriptor Exhaustion)
