kernel: "Dirty Frag" ESP XFRM variant is a new universal Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's xfrm-ESP and RxRPC subsystems. Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The...

io.vertx/vertx-core: static handler component cache can be manipulated to deny the access to static files

A flaw was found in Vert.x. The Web static handler component cache can be manipulated to deny the access to static files served by the handler using specifically crafted request URIs, preventing legitimate users from accessing static files with an HTTP 404 response...

CVE-2026-34042

A flaw was found in act. The built-in actions/cache server in act listens on all network interfaces, allowing a remote attacker to create and retrieve caches with arbitrary keys. By predicting cache keys used by local actions, an attacker can inject malicious files into caches. This vulnerability...

SUSE CVE-2026-34042

act is a project which allows for local running of github actions. Prior to version 0.2.86, act's built in actions/cache server listens to connections on all interfaces and allows anyone who can connect to it including someone anywhere on the internet to create caches with arbitrary keys and...

DEBIAN-CVE-2026-28369

A flaw was found in Undertow. When Undertow receives an HTTP request where the first header line starts with one or more spaces, it incorrectly processes the request by stripping these leading spaces. This behavior, which violates HTTP standards, can be exploited by a remote attacker to perform...

SUSE CVE-2026-25518

cert-manager adds certificates and certificate issuers as resource types in Kubernetes clusters, and simplifies the process of obtaining, renewing and using those certificates. In versions from 1.18.0 to before 1.18.5 and from 1.19.0 to before 1.19.3, the cert-manager-controller performs DNS...

PT-2026-6430

Impact The cert-manager-controller performs DNS lookups during ACME DNS-01 processing for zone discovery and propagation self-checks. By default, these lookups use standard unencrypted DNS. An attacker who can intercept and modify DNS traffic from the cert-manager-controller pod can insert a...

Vert.x Web static handler component cache can be manipulated to deny the access to static files

The Vert.x Web static handler component cache can be manipulated to deny the access to static files served by the handler using specifically crafted request URI. The issue comes from an improper implementation of the C. rule of section 5.2.4 of RFC3986 and is fixed in Vert.x Core component used b...

CVE-2026-1002

CVE-2026-1002 affects the Vert.x Web static handler cache. The issue stems from an improper implementation of the RFC3986 C-rule (section 5.2.4), enabling an attacker to craft a URI (e.g., bar%2F..%2F) that can cause denial of access to static files served by the handler. Connected evidence indic...
