USN-8727-1: Linux kernel (OEM) vulnerabilities

It was discovered that some Arm processors could complete a broadcast translation lookaside buffer TLB invalidation before memory writes made through the invalidated translation were globally observed. A local attacker could possibly use this to write to memory after permission to do so had been...

Cloudflare Workers Spectre Attack Leaks JWT From Co-Located Worker at 12 Bits/Second

Cybersecurity researchers have disclosed details of a remote Spectre attack against Cloudflare Workers that leaked a JSON Web Token JWT from a co-located Worker in the production environment at up to 12 bits per second, 360 times the rate of an earlier attack demonstrated in 2021. The end-to-end...

CVE-2026-72279

A flaw was found in the KVM Kernel-based Virtual Machine component of the Linux kernel. KVM on arm64 architectures incorrectly maps the L1 Virtual Nested Control Register VNCR into the host stage-1, failing to respect read-only memory regions. This could allow a malicious guest to write to a...

EUVD-2026-43696

On Xtensa SoCs built with CONFIGXTENSAMPU and CONFIGUSERSPACE, archbuffervalidate in arch/xtensa/core/mpu.c — the architecture hook that verifies a user-mode-supplied buffer is accessible to the calling user thread with the requested permission — defaulted its return value to 0 access permitted a...

CVE-2026-10669

Summary (CVE-2026-10669) : On Xtensa SoCs with CONFIG_XTENSA_MPU and CONFIG_USERSPACE, arch_buffer_validate() erroneously permits access when the buffer size rounds to a wrap of the 32-bit address space, bypassing MPU checks. This can let an unprivileged user-thread validate or copy memory it sho...
