GHSA-3W5P-95MH-GQ75 NCalc: Denial of Service via Unbounded and Non-Terminating Factorial Evaluation

Impact A denial-of-service DoS vulnerability exists in the factorial operator implementation of NCalc. Specially crafted expressions containing extremely large factorial operands can trigger excessive CPU consumption or cause evaluation to enter a non-terminating loop due to integer overflow in t...

CVE-2026-46101

A flaw was found in the Linux kernel's Netfilter subsystem. Specifically, the nftbitwise expression incorrectly handles zero shift operands during initialization. This can lead to undefined behavior within the kernel, potentially causing system instability. An attacker could exploit this by...

CVE-2026-46101

In the Linux kernel, the following vulnerability has been resolved: netfilter: reject zero shift in nftbitwise Reject zero shift operands for nftbitwise left and right shift expressions during initialization. The carry propagation logic computes the carry from the adjacent 32-bit word using...

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 nftbitwise not rejecting zero-shifted operand operations, potentially leading to undefined behavi...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/xe/xemigrate: Casting to output precision before multiplying operands This issue addressed potential overflows that could occur when multiplying two operands with lower precision u32, before widening them to a higher precisio...

SandboxJS has a sandbox escape via Function.caller leakage of internal call op

Summary Sandbox-defined functions expose Function.caller, allowing sandboxed code to recover the internal LispType.Call runtime callback. That callback can then be invoked with attacker-controlled fake context and obj values to extract blocked host statics, recover the real host Function...

CVE-2026-43896 jq: Stack Overflow in Recursive Object Merge

jq is a command-line JSON processor. In 1.8.1 and earlier, unbounded recursion in jvobjectmergerecursive allows a crafted jq program to crash the process with a segfault. The function is reachable through the operator when both operands are objects...

jq 安全漏洞

jq is a lightweight and flexible command-line JSON processor developed by jqlang. Jq versions 1.8.1 and earlier have security vulnerabilities; these vulnerabilities stem from unbounded recursion in jvobjectmergerecursive. This recursion allows malicious programs to cause program crashes with...
