EUVD-2026-38705

In the Linux kernel, the following vulnerability has been resolved: xfrm: espintcp: do not reuse an in-progress partial send espintcp keeps a single in-flight transmit in ctx-partial. Before building a new skmsg, espintcpsendmsg first tries to flush that state through espintcppushmsgs. For blocki...

CVE-2026-52935

The CVE-2026-52935 entry concerns the Linux kernel xfrm/espintcp code. The issue arises from reusing an in-progress partial transmit state (ctx->partial) when building a new sk_msg, where espintcp_sendmsg() may prematurely reuse the live partial if espintcp_push_msgs() reports success while a ...

CVE-2026-52927

CVE-2026-52927 concerns the Linux kernel netfilter ebtables path, specifically compat_mtw_from_user.

CVE-2026-12892

A flaw was found in GStreamer's gst-plugins-bad package. When processing a specially crafted H.264 video file containing malformed MVC or SVC extension slice NAL units, a 1-byte heap out-of-bounds read can occur during parsing. This happens when the parser attempts to check slice boundary...

Vulnerability Reports Are Not Special Anymore

A requirement for staying sane while working in public as an open source maintainer is realizing that every issue, PR, and piece of feedback is a present, not an obligation. You can accept it, ignore it, and use it partially or not at all. Except… For years, as lead of the Go Security team at the...

JLSEC-2026-621 Thread-safety and out-of-bounds reads in the HTTP.jl content-type sniffer

Description The content-type sniffer had two memory/concurrency bugs. Number sniffing in isjson stored the strtod end-pointer out-parameter in a shared module-global VectorPtrUInt8; concurrent sniff calls on a multithreaded server raced on that single cell between the ccall and the subsequent rea...

CVE-2026-56315

CVE-2026-56315 affects the Python tool picklescan until version 1.0.4, which fails to block imports from at least seven standard library modules (e.g., uuid, _osx_support, _aix_support, _pyrepl.pager, imaplib). This allows adversaries to craft pickle files that import these unblocked modules to t...

MessagePack for C is a MessagePack serializer for C. Prior to 2.5.301 and 3.1.7, MessagePack-CSharp's typeless deserialization includes MessagePackSerializerOptions.ThrowIfDeserializingTypeIsDisallowedType as a safety check for dangerous types. The default implementation checks the outer type nam...

kernel: wifi: mac80211: use safe list iteration in radar detect work

A flaw was found in the Linux kernel's mac80211 wireless subsystem. This vulnerability arises from unsafe list iteration during radar detection work, where a channel context can be freed while still being processed. This can lead to a use-after-free memory error. A successful exploit could result...
