Astra Linux – Vulnerability in libsoup2.4

A flaw was discovered in libsoup. An integer underflow vulnerability occurs when processing content with a zero-length resource, resulting in a buffer overread. This can allow an attacker to potentially access sensitive information or cause a denial of service at the application level...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, there was a heap buffer over-read vulnerability when processing images with small dimensions using the -wavelet-denoise operator. Versions 7.1.2-15 and 6.9.13-4...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, a buffer overread could occur in the freerdpimagecopyfromicondata function libfreerdp/codec/color.c, due to malicious RDP window icon TSICONINFO data. This bug could be exploited over the network when a clie...

EUVD-2026-54225

Contiki-NG's DNS/mDNS resolver skipname in os/services/resolv/resolv.c walks DNS wire-format name labels with no packet-boundary check, and the caller in newdata invokes it in a loop iterating nquestions times from the attacker-controlled DNS header before validating the transaction ID. An attack...

Linux Distros Unpatched Vulnerability : CVE-2026-71498

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - node-re2 provides RE2 regular expression bindings for Node.js. Prior to version 1.26.1, passing a Buffer whose final bytes form a truncated incomplete multi-byt...

postfix: buffer over-read via malformed enhanced status code

A flaw was found in Postfix. This issue occurs when processing enhanced status codes, specifically an enhanced status code that lacks text following the third number. Depending on the configuration of the server, this allows a remote attacker to cause a buffer over-read of only 1 byte, leading to...

Important: Red Hat Security Advisory: postfix security update

An update for postfix is now available for Red Hat Enterprise Linux 10.0 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available fo...

node-re2: Out-of-bounds heap read in `replace`/`split` via a `Buffer` ending in a truncated multi-byte UTF-8 character → adjacent heap memory disclosed to JavaScript

Summary re2 infers a character's byte length from its UTF-8 lead byte alone, with no bound on the bytes actually remaining in the input. Buffer arguments reach the native layer verbatim — only strings are re-encoded into well-formed UTF-8 — so a Buffer whose last byte is a multi-byte lead promise...

CVE-2026-71498

node-re2 provides RE2 regular expression bindings for Node.js. Prior to version 1.26.1, passing a Buffer whose final bytes form a truncated incomplete multi-byte UTF-8 sequence could cause the native binding to read past the end of the allocated buffer while attempting to decode the final,...

UBUNTU-CVE-2026-19027

The H5Znbitdecompressonebyte, H5Znbitdecompressonenooptype, and H5Znbitdecompressoneatomic functions in H5Znbit.c in HDF5 through 2.3.0 advance a read index into the compressed chunk buffer without bounding it against the buffer's actual size. This allows attackers to cause an out-of-bounds heap...

The vulnerability of the switchtec_ntb_init_mw() function in the drivers/ntb/hw/mscc/ntb_hw_switchtec.c driver for Linux’s non-visible kernel bridges allows a attacker to access protected information or cause service failures.

The vulnerability of the switchtecntbinitmw function in the drivers/ntb/hw/mscc/ntbhwswitchtec.c driver for Linux’s non-visible kernel bridges is related to reading beyond the buffer boundaries. Exploiting this vulnerability could allow an attacker to access protected information or cause service...
