Name of the Vulnerable Software and Affected Versions MessagePack for C versions prior to 2.5.301 MessagePack for C versions prior to 3.1.7 Description Multi-dimensional array formatters read dimension lengths directly from the payload and allocate T,, T,,, or T,,, before validating that the...

Libheif 1.19.x < 1.23.0 DoS (macOS)

According to its self-reported version, libheif on the remote host is affected by a denial of service vulnerability. A crafted HEIF sequence file can cause libheif to perform unbounded heap allocation due to a missing bound check in the stsz fixed-size mode of the HEIF sequence parser, leading to...

SUSE CVE-2026-10118

A flaw was found in Poppler's Splash backend. A remote attacker could exploit this vulnerability by crafting a malicious PDF file that, when rendered, triggers an integer overflow in the tilingPatternFill function. This overflow leads to an undersized heap memory allocation, allowing a subsequent...

Security update for 389-ds

This update for 389-ds fixes the following issue CVE-2026-9064: unbounded LDAP controls count in getldapmessagecontrolsext can lead to amplified CPU time and heap allocation and a denial of service bsc1265898. Changes for 389-ds: Update to version 2.0.20git90.9f70d434e. Patch Instructions: To...

FreeBSD Security Advisory - FreeBSD-SA-26:34.vt

FreeBSD Security Advisory - The CONSHISTORY ioctl handler did not adequately validate the requested history size. A large value caused an integer overflow in the buffer size calculation, resulting in a heap allocation smaller than expected. Subsequent initialization of the buffer wrote beyond the...

FreeBSD -- Integer overflow in vt(4) CONS_HISTORY ioctl

Problem Description: The CONSHISTORY ioctl handler did not adequately validate the requested history size. A large value caused an integer overflow in the buffer size calculation, resulting in a heap allocation smaller than expected. Subsequent initialization of the buffer wrote beyond the end of...

Use-after-free

Affected versions of oneringbuf exposed the obsolete IntoRef::intoref method through the public IntoRef trait. For heap-backed ring buffers, this method returned a DroppableRef handle. DroppableRef stored an owning raw pointer created from Box::intoraw. Its Clone implementation copied this raw...

CVE-2026-44983

smallbitvec is a growable bit-vector for Rust, optimized for size. From 1.0.1 to 2.6.0, an integer overflow in the internal capacity calculation of smallbitvec can lead to an undersized heap allocation, resulting in a heap buffer overflow through safe APIs only. This allows memory corruption...

CVE-2026-42627

In Arm ArmNN through 2026-03-27, an integer overflow in TensorShape::GetNumElements in armnn/Tensor.cpp allows a crafted TFLite model file to bypass buffer size validation and trigger a heap-based buffer over-read during model optimization. The overflow occurs when multiplying tensor dimensions...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/lima: fixed a memory leak in limaheapalloc. When limavmmapbo fails, the resources need to be deallocated; otherwise, memory leaks will occur...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: ksmbd: Validated numaces and hardened the ACE walk in smbinheritdacl. smbinheritdacl relies on the numaces value from the parent directory’s DACL xattr and uses it to allocate memory for the heap: acesbase = kmallocsizeofstruc...

CVE-2026-32740

libheif is a HEIF and AVIF file format decoder and encoder. Versions 1.21.2 and prior contain a heap-buffer-overflow write vulnerability in the grid tile compositing, allowing an attacker to write 64 bytes of fully attacker-controlled data past the end of a chroma plane heap allocation by craftin...

GHSA-V2FC-QM4H-8HQV Nokogiri XSLT transform has a memory leak

Summary Nokogiri's Nokogiri::XSLT::Stylesheettransform leaks a small heap allocation when passed a Ruby string parameter containing a null byte. For applications that pass attacker-controlled input through XSLT.transform parameters, this may be a vector for a denial of service attack against...

CVE-2026-42154

Prometheus is an open-source monitoring system and time series database. Prior to versions 3.5.3 and 3.11.3, the remote read endpoint /api/v1/read does not validate the declared decoded length in a snappy-compressed request body before allocating memory. An unauthenticated attacker can send a sma...

CVE-2026-29004

BusyBox prior to commit 42202bf contains a heap buffer overflow in the DHCPv6 client (udhcpc6) DNS_SERVERS option handler (networking/udhcp/d6_dhcpc.c). Attackers on the network-adjacent path can trigger memory corruption by sending a crafted DHCPv6 response with a malformed D6_OPT_DNS_SERVERS op...

CVE-2026-31706

A flaw was found in ksmbd, a Linux kernel module that provides an in-kernel SMB server. An authenticated client can exploit this vulnerability by manipulating the numaces value within the parent directory's security.NTACL extended attribute. This manipulation causes ksmbd to attempt an excessivel...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the fact that the function smbinheritdacl does not verify the numaces value. This can lead to...
