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 underflow in the reference counting mechanism used in intelengineparkheartbeat. This...

PVAC: A RowHammer Mitigation Architecture Exploiting Per-Victim-Row Counting

As DRAM scaling exacerbates RowHammer, DDR5 introduces per-row activation counting PRAC to track aggressor activity. However, PRAC indiscriminately increments counters on every activation -- including benign refreshes -- while relying solely on explicit RFM operations for resets. Consequently,...

GHSA-R7W7-9XR2-QQ2R langchain-openai: Image token counting SSRF protection can be bypassed via DNS rebinding

Summary langchain-openai's urltosize helper used by getnumtokensfrommessages for image token counting validated URLs for SSRF protection and then fetched them in a separate network operation with independent DNS resolution. This left a TOCTOU / DNS rebinding window: an attacker-controlled hostnam...

CVE-2026-33023

libsixel is a SIXEL encoder/decoder implementation derived from kmiya's sixel. In versions 1.8.7 and prior, when built with the --with-gdk-pixbuf2 option, a use-after-free vulnerability exists in loadwithgdkpixbuf in loader.c. The cleanup path manually frees the sixelframet object and its interna...

CVE-2026-4437: fix incorrect record counting in getanswerptr that allowed iteration past the answer section boundary in DNS responses - CVE-2026-4438: fix hostname validation checking expectedname instead of namebuffer in getanswerptr, which could return invalid hostnames...

JLSEC-2026-90

Poppler is a PDF rendering library. Versions prior to 25.06.0 use std::atomicint for reference counting. Because std::atomicint is only 32 bits, it is possible to overflow the reference count and trigger a use-after-free. Version 25.06.0 patches the issue...

kernel: Linux kernel: Use-After-Free vulnerability in ATM subsystem

A flaw was found in the Linux kernel's Asynchronous Transfer Mode ATM subsystem. An authenticated local attacker could exploit a Use-After-Free UAF vulnerability in the /proc/net/atm/lec handling. This flaw occurs due to improper devput calls without prior devhold calls, leading to an imbalance i...
