CVE-2026-97033

Unexpected code execution via --sysroot, -target, -isysroot, -Wl,-syslibroot, and -x cgo flags in cmd/go

Building a malicious package that uses cgo could cause arbitrary code execution at build time through several compiler and linker flags permitted in "#cgo" directives. Specifically, "--sysroot" in GCC and Clang relocates compiler subprograms, spec files, and CRT startup objects to an attacker-controlled directory; "-target" in Clang falls back to executing target helper tools from the current working directory when not found in PATH; "-isysroot" and "-Wl,-syslibroot" can pass a regular file on disk to GNU ld.bfd, which interprets it as a positional linker script; and "-x" permitted specifying arbitrary compiler input languages beyond those supported by cgo. "--sysroot" and "-target" are now disallowed in "#cgo" flags, "-isysroot" and "-Wl,-syslibroot" are verified not to point to regular files, and "-x" is restricted to the C, C++, Objective-C, and assembler languages supported by cgo.

CVE-2026-126720

CVE-2026-126720

Rooxis RXR-12 Wi-Fi router contains an unauthenticated remote code execution vulnerability in /usr/bin/cloud_manage, where a server-controlled JSON diagnoseParameter field is passed unsanitized to popen(), enabling arbitrary command execution as root over cleartext HTTP when an attacker is positioned on-path and has access to the hard-coded cloud endpoint. Firmware 20260813_c2169ea5 fixes the vulnerability, and your router can be updated through the local web interface.

CVE-2026-119237

Denial of Service Vulnerability in Facebook Proxygen HTTP/3 QPACK Header Processing

In proxygen's HTTP/3 session, when a HEADERS block referenced QPACK dynamic table entries that had not yet been received, header decoding for that stream was paused, but the session continued to read the stream from the QUIC transport. The unread data bypassed the session's ingress buffer limit, returned flow-control credit to the peer, and was re-scanned in full on every read. With QPACK blocked streams enabled (the default), a remote, unauthenticated HTTP/3 peer could send a HEADERS block that references a dynamic table insert it never sends, followed by a continuous stream of data, causing memory growth until the request timed out and CPU usage that grows quadratically, leading to denial of service. This issue affects proxygen versions prior to v2026.11.09.00.

Path Traversal (Tar Slip) in Lenovo XClarity OneCLI 5.5.0 Linux

A path traversal vulnerability in the TAR.GZ extraction logic of Lenovo XClarity Essentials OneCLI 5.5.0 for Linux could allow an attacker to write arbitrary files with the privileges of the OneCLI process by convincing a user to process a specially crafted TAR.GZ update package.

HTTP/1 server crash due to MaxBytesReader header race in net/http

For HTTP/1 servers, when MaxBytesReader's limit is exceeded, "Connection: close" header is automatically set without synchronization, which might race with another header being set explicitly in the server handler. As a result, an HTTP/1 server that utilizes MaxBytesReader or MaxBytesHandler can crash due to runtime panic if its handler reads the request body concurrently with writing the response header.

CVE-2026-119234

Memory Exhaustion Through QUIC Fragment Storage in mvfst

mvfst did not adequately merge or compact out-of-order STREAM frame data, and a small received fragment could keep a much larger receive buffer alive. QUIC flow control limits the number of buffered stream bytes, but not this per-fragment memory and bookkeeping. A remote, unauthenticated QUIC peer could send many small, non-contiguous stream fragments to make an endpoint consume memory far in excess of its advertised receive window and spend increasing CPU time reassembling stream data, leading to denial of service. This issue affects mvfst versions prior to v2026.11.09.0.
