CVE-2026-72367 iomap: guard io_size EOF trim against concurrent truncate underflow

In the Linux kernel, the following vulnerability has been resolved: iomap: guard iosize EOF trim against concurrent truncate underflow iomap: fix zero padding data issue in concurrent append writes changed ioend accounting so that iosize tracks only valid data within EOF. This trims iosize when a...

CVE-2026-68145

A flaw was found in the Linux kernel's iomap subsystem. An unsigned subtraction underflow occurs when ifssetrangedirty or ifssetrangeuptodate are called with a zero-length range. This can lead to an out-of-bounds write via bitmapset, potentially allowing a local attacker to cause memory corruptio...

CVE-2026-59090

A flaw was found in GIMP's PSD file format plugin. This vulnerability, an unsigned integer underflow in the blockrem variable, occurs when a user opens a specially crafted .psd image file. The underflow leads to parser confusion, enabling an attacker to inject arbitrary data as layer resource...

CVE-2026-59090 Gimp: gimp: arbitrary code execution in psd plugin due to unsigned underflow

A flaw was found in GIMP's PSD file format plugin. This vulnerability, an unsigned integer underflow in the blockrem variable, occurs when a user opens a specially crafted .psd image file. The underflow leads to parser confusion, enabling an attacker to inject arbitrary data as layer resource...

CVE-2026-59090

GIMP-PSDs: The CVE affects GIMP’s PSD file format plugin, where an unsigned integer underflow in block_rem during parsing of a crafted .psd file can trigger parser confusion, enabling an attacker to inject arbitrary data as layer resource blocks and potentially achieve arbitrary code execution on...

Astra Linux – Vulnerability in gpsd

There is an integer underflow vulnerability in the nextstate function in gpsd/packet.c in gpsd versions prior to the commit ffa1d6f40bca0b035fc7f5e563160ebb67199da7. When parsing a NAVCOM packet, the payload length is calculated using lexer-length = sizetc - 4, without checking whether the input...

Astra Linux – Vulnerability in libheif

libheif is a decoder and encoder for HEIF and AVIF file formats. In versions 1.21.2 and earlier, a crafted 792-byte HEIF sequence file with samplesperchunk=0 in the stsc field could cause an unsigned integer underflow in the Chunk constructor mlastsample = 0 + 0 - 1 = UINT32MAX, causing all sampl...

CVE-2026-54345 GoPacket's Diameter AVP decoder: uint32 underflow on vendor header size leads to unbounded ~4 GiB allocation (unauthenticated remote DoS)

gopacket provides packet processing capabilities for Go. In version 1.6.0 and earlier, the Diameter AVP decoder computes an AVP data length by subtracting a fixed header size from an attacker-controlled AVP Length field, so a vendor-flagged AVP whose Length is smaller than the 12-byte header...
