PT-2026-79992

Integer underflow in PostgreSQL ECPG allows a database server administrator to achieve temporary denial of service against the ECPG client via sending a bytea value lacking the mandatory prefix. The client overwrites a huge memory region with bytes outside attacker knowledge or control. This...

PT-2026-78362

Name of the Vulnerable Software and Affected Versions nnn version 5.2 Description The software stores the homelen variable as a uchar t, which limits its range to 0-255. An attacker capable of influencing the execution environment can provide a HOME path with a length that is truncated to 0. This...

CVE-2026-62289

libheif is a HEIF and AVIF file format decoder and encoder. In 1.23.0 and earlier, a crafted HEIF or AVIF file containing a clean aperture box can reduce an image dimension to zero and crash or corrupt tiling results when heifimagehandlegetimagetilinghandle, 1, &tiling is called...

CVE-2026-62289

libheif ≤1.23.0 applies clean aperture transformation twice via process_image_transformations_on_tiling(), causing integer underflow in Box_clap::left_rounded(0) that constructs Fraction(0xFFFFFFFF, 2). Debug builds abort on assertion; release builds produce corrupt crops. Fixed in 1.23.1; Debian...

SUSE CVE-2026-68145

In the Linux kernel, the following vulnerability has been resolved: iomap: fix out-of-bounds bitmapset with zero-length range ifssetrangedirty and ifssetrangeuptodate compute lastblk as off + len - 1 iblkbits. When off is 0 and len is 0, the unsigned subtraction underflows to SIZEMAX, producing a...

GO-2026-6170 WITHDRAWN: Malformed backend frame length causes panic in github.com/lib/pq

This report has been withdrawn with reason: "Report mistakenly added without having CVE / GHSA associated". github.com/lib/pq trusts the unsigned 32-bit length in every PostgreSQL backend frame and subtracts four without first checking that the wire length is at least four. A backend frame whose...

CVE-2026-72195

A flaw was found in the Linux kernel's ntfs3 file system driver. An integer underflow vulnerability occurs in the UpdateResidentValue function when processing a maliciously crafted Log Record Header LRH. This underflow can lead to an incorrect calculation of datasize, allowing subsequent operatio...

CVE-2026-72191

A flaw was found in the Linux kernel's ntfs3 driver. A local attacker can exploit this vulnerability by mounting a specially crafted NTFS filesystem image. This can lead to an integer underflow during a memory copy operation, resulting in an out-of-bounds kernel write. Successful exploitation...

CVE-2026-72382

A flaw was found in ksmbd in the Linux kernel. A remote attacker, by sending a specially crafted security descriptor with an undersized Discretionary Access Control List DACL during an SMB2SETINFO operation, can trigger an integer underflow. This underflow leads to excessive memory allocations fo...

SUSE CVE-2026-18727

A flaw was found in open-iscsi's iscsiuio component. This vulnerability involves an integer underflow and out-of-bounds read during Dynamic Host Configuration Protocol for IPv6 DHCPv6 packet parsing.
