CVE-2022-2869-detector

CVE-2022-2869 CodeQL Detector This project implements a general CodeQL detector for the root weakness behind CVE-2022-2869: an unsigned subtraction that may underflow because the program has not established a sufficient lower-bound/order guard before the arithmetic. Why this version is different...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/i915/selftests: fixed the subtraction overflow bug. On some machines, holeend can be small enough to cause subtraction overflow. On the other hand, addr + 2 minalignment can cause overflow in case of mock tests. This patch...

Linux Distros Unpatched Vulnerability : CVE-2026-89551

"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - SUNRPC: xdrbuftrim: clamp buf-len to avoid underflow xdrbuftrim trims len bytes from the tail of an xdrbuf by walking the tail, pages, and head iovecs. Each...

CVE-2026-89551

CVE-2026-89551 is a CRITICAL (CVSS 9.8) integer underflow in the Linux kernel's SUNRPC subsystem. The xdr_buf_trim() function subtracts consumed bytes from buf->len without clamping, so when called from gss_krb5_unwrap_v2() with a small wire-derived buf->len while page-scale iov_lens are pr...

DEBIAN-CVE-2026-18355

A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server 389-ds-base. In sasliostartpacket, the wrapped-record length read from the wire is validated only against an upper bound. A small wire length 0, 1, or 2 produces an encryptedbuffercount below the already-consumed...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/sun4i: dsi: Prevent underflow when calculating packet sizes. Currently, the packet overhead is subtracted using unsigned arithmetic. With a short sync pulse, this could lead to an underflow, causing the value to wrap around t...

CVE-2026-68196

CVE-2026-68196 affects the Linux kernel wilc1000 Wi-Fi driver. A malformed association response can lead to an out-of-bounds read due to improper validation when computing trailing IE length (ies_len = buffer_len - sizeof(*res)) without verifying buffer_len against the fixed header. Short frames ...

CVE-2026-68196 wifi: wilc1000: validate assoc response length before subtracting header

In the Linux kernel, the following vulnerability has been resolved: wifi: wilc1000: validate assoc response length before subtracting header wilcparseassocrespinfo computes the trailing IE length as ieslen = bufferlen - sizeofres; without first checking that bufferlen is at least sizeofstruct...

EUVD-2026-40996

FatFs R0.16 and earlier exhibits a stale dirty-cache skip via unsigned-subtraction wrap in fread / fwrite fp-sect - sect cc during interleaved read/write on fragmented filesystems. This maps to CWE-191 Integer Underflow. Estimated CVSS v3.1 vector: CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H 6.1...

CVE-2026-6685

CVE-2026-6685 refers to an Integer Underflow in FatFs during dirty-sector cache flush when handling fragmented volumes. Affected software is FatFs R0.16 and earlier; the issue arises from an unsigned-subtraction wrap in cache handling (fp->sect vs. sect) during interleaved read/write, which ca...

CVE-2026-26981

OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry. In versions 3.3.0 through 3.3.6 and 3.4.0 through 3.4.4, a heap-buffer-overflow OOB read occurs in the istreamnonparallelread function in...

Azure Linux 3.0 Security Update: jq (CVE-2024-53427)

The version of jq installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-53427 advisory. - decNumberCopy in decNumber.c in jq through 1.7.1 does not properly consider that NaN is interpreted as numeric,...
