Linux Distros Unpatched Vulnerability : CVE-2026-49346

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - libde265 is an open source implementation of the h.265 video codec. Prior to version 1.1.0, a crafted H.265 bitstream with large SPS dimensions and 16-bit bit...

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-2023-29146

The utility functions used by Malwarebytes EDR 1.0.11 on Linux for calculating a cryptographic hash of data bytes truncate the hashed data if it exceeds 4GB. This leads to an integer wrap-around if the data is larger than the maximum unsigned integer value 32-bit. Attackers could create a collidi...

JLSEC-2026-601

Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds. This may execute arbitrary code as the operating system user running the database. In applications that pass gigabyte-scale user...

CVE-2026-48101 GHSL-2026-117: 7-Zip UEFI Capsule uninitialized heap memory disclosure

7-Zip is a file archiver with a high compression ratio. Versions 9.21 through 26.00 contain an An uninitialized memory disclosure vulnerability in the UEFI capsule .scap parser in 7-Zip. The OpenCapsule function allocates a heap buffer of attacker-declared CapsuleImageSize up to 1 GiB without...

CVE-2026-44697

Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.17, a remote, unauthenticated denial-of-service vulnerability in Batch.Decompress data/batch/batch.go allows any peer that participates in a topic served by MultiDataInterceptor to allocate multi-gigabyte heaps on...

CVE-2026-48959

IO::Uncompress::Unzip versions before 2.220 for Perl allow CPU exhaustion via per-byte read loop in fastForward. fastForward compares length $offset the digit count of the offset, 1 to 19 against the chunk size $c instead of $offset itself, so $c shrinks from 16 KiB to 1-19 bytes per iteration...

DEBIAN-CVE-2026-9538

Archive::Tar versions before 3.10 for Perl allow memory exhaustion via attacker controlled entry size field in tar header. readtar reads each entry's payload with $handle-read$$data, $block, where $block is derived from the entry's 12-byte size field in the tar header with no upper bound on that...

UBUNTU-CVE-2026-9538

Archive::Tar versions before 3.10 for Perl allow memory exhaustion via attacker controlled entry size field in tar header. readtar reads each entry's payload with $handle-read$$data, $block, where $block is derived from the entry's 12-byte size field in the tar header with no upper bound on that...

CVE-2026-9538

CVE-2026-9538 affects Archive::Tar prior to 3.10 for Perl. A crafted tar header can set a multi‑gigabyte size, causing _read_tar() to allocate a scalar of that size, leading to memory exhaustion. The vulnerability arises from reading entry payloads with a size block derived from the header withou...

CVE-2026-9538

Archive::Tar versions before 3.10 for Perl allow memory exhaustion via attacker controlled entry size field in tar header. readtar reads each entry's payload with $handle-read$$data, $block, where $block is derived from the entry's 12-byte size field in the tar header with no upper bound on that...

Archive::Tar versions before 3.10 for Perl allow memory exhaustion via attacker controlled entry size field in tar header. readtar reads each entry's payload with $handle-read$$data, $block, where $block is derived from the entry's 12-byte size field in the tar header with no upper bound on that...

CVE-2026-39834

When writing data larger than 4GB in a single Write call on an SSH channel, an integer overflow in the internal payload size calculation caused the write loop to spin indefinitely, sending empty packets without making progress. The size comparison now uses int64 to prevent truncation...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Fixed KMS with 3D support in the HW version 10. The HW version 10 does not have GB Surfaces, so there is no backing buffer for surface-backed FBs. This could lead to a nullptr dereference, causing the driver to crash...

Astra Linux – Vulnerability in glib2.0

A issue was discovered in GNOME GLib before versions 2.66.7 and 2.67.x before version 2.67.4. If the gbytearraynewtake function was called with a buffer of 4GB or more on a 64-bit platform, the length would be truncated modulo 2^32, resulting in unintended length truncation...

Astra Linux – Vulnerability in Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: x86/mm/identmap: Use GB pages only when a full GB page should be mapped. When identpudinit uses only GB pages to create identity maps, large ranges of addresses that are not actually requested can be included in the resulting...

EUVD-2026-30708

Crypt::OpenSSL::PKCS12 versions through 1.94 for Perl have out-of-bounds OOB write flaws. When parsing a PKCS12 file, with a = 1 GiB OCTET STRING or BIT STRING attribute on a SAFEBAG, via info or infoashash, a heap out-of-bounds write would be triggered with remote-code-execution potential RCE du...

CVE-2026-6473

Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds. This may execute arbitrary code as the operating system user running the database. In applications that pass gigabyte-scale user...

CVE-2026-6473 PostgreSQL server undersizes allocations, via integer wraparound

Integer wraparound in multiple PostgreSQL server features allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds. This may execute arbitrary code as the operating system user running the database. In applications that pass gigabyte-scale user...

EUVD-2026-29172

jq is a command-line JSON processor. In 1.8.1 and earlier, when decNumberFromString is given a number literal of INTMAX-1 2147483646 digits, the D2U macro overflows during signed-int arithmetic. The wrapped negative value bypasses the heap-allocation size check, causes the function to use a 30-by...
