QEMU calc_image_hostmem Integer Overflow Local Privilege Escalation Vulnerability

This vulnerability allows local attackers to escalate privileges on affected installations of QEMU. An attacker must first obtain the ability to execute low-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the virtio-gpu driver. Th...

UBUNTU-CVE-2026-46305

In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: osdep: avoid NULL pointer dereference in rtwcbufalloc The return value of kzallocflex is used without ensuring that the allocation succeeded, and the pointer is dereferenced unconditionally. Guard the access t...

CVE-2026-46305

CVE-2026-46305 affects the Linux kernel, specifically the staging/rtl8723bs path. The issue arises when kzalloc_flex()’s return value is used without checking for allocation failure, leading to a potential NULL pointer dereference when accessing the allocated structure. The fix guards access to t...

CVE-2026-44004

A flaw was found in vm2 before 3.11.0. Sandboxed code can call Buffer.alloc with arbitrary size to allocate on the host heap synchronously; vm2 timeout cannot interrupt the native C++ call, allowing a single request to exhaust host memory and crash the process. Fixed in 3.11.0...

CVE-2026-10879

DBI versions before 1.648 for Perl have a heap overflow when preparsing SQL statements with more than 9 binders. The preparse method expands SQL placeholder characters to numbered binders of the form :pN, but only allocates three characters per binder in the buffer. Placeholders 10-99 require fou...

CVE-2026-46272

In the Linux kernel, the following vulnerability has been resolved: coresight: tmc-etr: Fix race condition between sysfs and perf mode When trying to run perf and sysfs mode simultaneously, the WARNON in tmcetrenablehw is triggered sometimes: WARNING: CPU: 42 PID: 3911571 at...

CVE-2026-46272

The CVE-2026-46272 issue is a race in the Linux kernel CoreSight TMC ETR driver that occurs when sysfs and perf modes are enabled concurrently. A WARN_ON in tmc_etr_enable_hw() can trigger due to a race between the two critical regions (sysfs buffer allocation vs. hardware enablement). The fix ad...

SUSE CVE-2026-46188

In the Linux kernel, the following vulnerability has been resolved: octeonepvf: add NULL check for napibuildskb napibuildskb can return NULL on allocation failure. In octepvfoqprocessrx, the result is used directly without a NULL check in both the single-buffer and multi-fragment paths, leading t...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from a bo leak that occurs when the xedmabufinitobj function fails during allocation in the drm/xe...

Linux Distros Unpatched Vulnerability : CVE-2026-48690

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - FastNetMon Community Edition through 1.2.9 contains an integer overflow vulnerability in the packet capture buffer allocation. In src/packetstorage.hpp, the...

CVE-2026-48690

FastNetMon Community Edition through 1.2.9 contains an integer overflow vulnerability in the packet capture buffer allocation. In src/packetstorage.hpp, the allocatebuffer function computes memorysizeinbytes as 'buffersizeinpackets maxcapturedpacketsize + sizeoffastnetmonpcappkthdrt +...

FastNetMon 安全漏洞

FastNetMon is a high-performance DDoS detector/sensor developed by Pavel Odintsov. It is based on multiple packet capture engines. Versions of FastNetMon Community Edition prior to 1.2.9 contained a security vulnerability caused by integer overflow during the allocation of packet capture buffers,...

CVE-2026-48690

CVE-2026-48690 affects FastNetMon Community Edition up to v1.2.9. The issue is an integer overflow in the packet capture buffer allocation: allocate_buffer() computes memory_size_in_bytes as buffer_size_in_packets * (max_captured_packet_size + sizeof(fastnetmon_pcap_pkthdr_t)) + sizeof(fastnetmon...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Ring Buffer: Check for NULL cpubuffer in ringbufferwakewaiters On some machines, the number of listed CPUs may be larger than the actual CPUs that exist. The tracing subsystem allocates a per-CPU directory with access to the...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: media: cx23885 – Fixed a nullptrderef bug in bufferprepare and bufferfinish. When the driver calls cx23885riscbuffer to prepare the buffer, the function call dmaalloccoherent may fail, resulting in an empty buffer risc-cpu. Later...

Unchecked `CryptoVec` allocation and growth handling

CryptoVec used unchecked capacity growth, unchecked length arithmetic, and unsafe allocation and locking paths. In affected russh releases, attacker-controlled input could reach these code paths through buffer resizing operations. Two affected reachability paths were identified: Current russh...

SUSE CVE-2026-42583

Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, Lz4FrameDecoder allocates a ByteBuf of size decompressedLength up to 32 MB per block before LZ4 runs. A peer only needs a 21-byte header plus compressedLength payload bytes - 22 bytes if...

CVE-2026-43905

OpenImageIO CVE-2026-43905 affects the JPEG2000 path when built with OpenJPH. In jpeg2000input.cpp:395, buffer size is computed as w * h * ch * buffer_bpp using 32-bit signed arithmetic, so when the product exceeds INT_MAX the result wraps to 0 or a small value. This yields an undersized m_buf an...

CVE-2026-43905 OpenImageIO: JPEG2000 (OpenJPH) signed integer overflow in buffer allocation

OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.18.0 and 3.1.13.0, jpeg2000input.cpp:395 computes buffer size as const int bufsize = w h ch bufferbpp using signed 32-bit arithmetic. When the product...

CVE-2026-8295 Integer overflow in simdjson

An integer overflow vulnerability in the simdjson document-builder API allows incorrect buffer size calculations in "stringbuilder::escapeandappend" when processing very large input strings on platforms with limited "sizet" width e.g., 32-bit builds. The overflow can cause insufficient buffer...
