CVE-2026-74657

A flaw was found in the Linux kernel. The fibnlmsgsize function, which estimates the size for network message buffers, incorrectly calculates the required space for nexthops when IPv4 routes contain an IPv6 gateway. This error can lead to the allocation of an undersized buffer for route...

PT-2026-81033

An integer overflow in the libtiff rgb2ycbcr utility's cvtRaster function when computing strip buffer sizes can result in an undersized heap allocation and subsequent heap-based buffer overflow during YCbCr conversion of a crafted TIFF image...

EUVD-2026-64594

In the Linux kernel, the following vulnerability has been resolved: ipv4: Fix fibnlmsgsize for RTAVIA nexthops fibnlmsgsize still estimates nexthop space as if every gateway is encoded as an IPv4 RTAGATEWAY attribute. IPv4 routes can also carry an IPv6 gateway, which fibnexthopinfo dumps as RTAVI...

PT-2026-79687

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: fix OOB write on Type II inbound URBs data ep set params sizes each URB transfer buffer before it adds the Format Type II transfer delimiter: u-packets = urb packs; u-buffer size = maxsize u-packets; if fmt-fmt...

DEBIAN-CVE-2026-70652

libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, libvips built with libultrahdr support can incorrectly size an output buffer in libvips/foreign/uhdrsave.c within vipsforeignsaveuhdrsetrawhdr when a pipeline enlarges an incoming JPEG to a very large outpu...

EUVD-2026-54161

FFmpeg versions from 3.0 up to, but not including, 9.0 contain an uninitialized heap memory read vulnerability in the native RSCC decoder libavcodec/rscc.c that allows attackers to disclose heap memory contents by supplying a crafted video file with a compressed tile that decompresses fewer bytes...

CVE-2026-64550

A flaw was found in the Linux kernel's Qualcomm rmnet component. This vulnerability occurs because the system does not properly check the size of incoming network packets, specifically MAP frames, when a certain network feature ingress deaggregation is turned off. A remote attacker could exploit...

CVE-2026-64548

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: reject overflowing copy + len in bpfmsgpushdata When the scatterlist ring is full or nearly full, bpfmsgpushdata enters a copy fallback path and computes copy + len for the page allocation size. Since len comes from...

postgresql: integer overflow can cause an undersized allocation and an out-of-bounds write

A flaw was found in PostgreSQL. An integer overflow in multiple server features allows an unprivileged database user to cause an undersized memory allocation that leads to an out-of-bounds write. This issue allows an attacker to execute arbitrary code as the operating system user running the...

CVE-2026-47714

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and prior, the inline mask parsing code in libheif/region.cc contains an integer overflow. Both width and height are unsigned int 32-bit values parsed from the HEIF file. Their product can exceed UINT32MAX, wrapping to...

CVE-2026-47714

The issue is a concrete, exploitable flaw in libheif up to version 1.21.2 (patched in 1.22.0) where inline mask size calculation in libheif/region.cc can overflow while parsing width and height as 32-bit unsigned ints. Their product can exceed UINT32_MAX, causing an undersized allocation and out-...

kernel: ipv4: account for fraggap on the paged allocation path

A flaw was found in the Linux kernel's handling of IPv4 network packets. An error in how the kernel accounts for fragmented data during memory allocation can lead to an undersized memory buffer. This memory handling issue could potentially be exploited by a remote attacker to cause a system crash...
