EUVD-2026-67445

In the Linux kernel, the following vulnerability has been resolved: s390/dasd: Fix undersized format-check buffer fmtbuffersize in dasdeckdcheckdeviceformat is declared as int, even though one of the multiplicands, sizeofstruct eckdcount, is a sizet. The expression trkcount rptmax sizeofstruct...

CVE-2026-80710

CVE-2026-80710 affects the s390/dasd subsystem of the Linux kernel. In dasd_eckd_check_device_format(), the variable fmt_buffer_size is declared as a 32-bit int, but the expression trkcount * rpt_max * sizeof(struct eckd_count) is evaluated at 64-bit width. When the track range (controlled by cal...

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...

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...

Linux Distros Unpatched Vulnerability : CVE-2026-70652

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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...

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-...

FreeRDP: FreeRDP: Heap buffer overflow allows arbitrary code execution via crafted pixel data

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A remote attacker could exploit a heap buffer overflow vulnerability in the resizevbarentry function. This occurs when an error in buffer resizing leads to attacker-controlled pixel data being written into an...

AZL-83825 CVE-2026-31630 affecting package kernel 6.6.150.1-1

In the Linux kernel, the following vulnerability has been resolved: rxrpc: proc: size address buffers for %pISpc output The AFRXRPC procfs helpers format local and remote socket addresses into fixed 50-byte stack buffers with "%pISpc". That is too small for the longest current-tree IPv6-with-port...

CVE-2026-35199 SymCrypt SymCryptXmssSign function - Heap overflow via 64->32-bit leaf-count truncation

SymCrypt is the core cryptographic function library currently used by Windows. From 103.5.0 to before 103.11.0, The SymCryptXmssSign function passes a 64-bit leaf count value to a helper function that accepts a 32-bit parameter. For XMSS^MT parameter sets with total tree height = 32 which include...
