GHSA-3RJW-M598-PQ24 Cmov/CmovEq on aarch64 can produce wrong results if high-bits of registers are set

Summary The aarch64 implementations of Cmov and CmovEq seem to assume that the high bits when loading a value of size smaller than a register into a register are zero-extended. However, this is not the case and these bits are unspecified. This can result in a left.cmovz&right, condition not movin...

USN-8499-1 linux-xilinx vulnerabilities

It was discovered that the Linux kernel algifaead module did not properly handle in-place cryptographic operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or possibly escape a container. CVE-2026-31431 It was discovered that the Linux kernel did n...

USN-8499-1: Linux kernel (Xilinx) vulnerabilities

It was discovered that the Linux kernel algifaead module did not properly handle in-place cryptographic operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or possibly escape a container. CVE-2026-31431 It was discovered that the Linux kernel did n...

curl: Information disclosure due to uncleared proxy authentication state

A flaw was found in libcurl. When reusing a libcurl handle for sequential transfers with environment-variable proxy configuration, the library does not properly clear the proxy authentication state. This oversight can lead to the unintended disclosure of Proxy-Authorization headers to an incorrec...

USN-8497-1: Linux kernel (Low Latency) vulnerabilities

It was discovered that the Linux kernel did not properly handle shared page fragments during socket buffer operations, collectively known as Dirty Frag. A logic flaw existed in the XFRM ESP-in-TCP subsystem and in the RxRPC networking subsystem when processing paged fragments. A local attacker...

ThreatsDay: AI Compute Hijacking, Apple Email Flaw, BlueHammer Ransomware + 14 Stories

This week’s security news is mostly about weak spots. Browsers, bots, sandboxes, AI systems, and email flows all show the same problem in different ways. Everything looks normal until someone tests a small gap and finds a way through. This is not one big break. It is small permissions, weak check...

Out-of-bounds Read in OpenCV

An out-of-bounds read was discovered in OpenCV before 4.1.1 OpenCV-Python before 4.1.0.25. Specifically, variable coarsestscale is assumed to be greater than or equal to finestscale within the calc/oclcalc functions in disflow.cpp. However, this is not true when dealing with small images, leading...

Identity Lifecycle Management Wasn't Built for AI Agents 

Identity lifecycle management was architected around a person with an employment record, a manager, and a departure date. AI agents have none of those. As autonomous principals proliferate across enterprise environments, the governance model built for humans develops structural blind spots that...
