ifuncd-up

In Response to Hacker News I see you jokers on the orange website are giving me a hard time. I will make a few choice responses below, but first I offer a challenge: I will send $500 of my own money to the first person who can demonstrate this attack without ifunc. I am genuinely interested, and...

Astra Linux – Vulnerability in amd64-microcode

IOMMU improperly handles certain special address ranges with invalid device table entries DTEs. This may allow an attacker with privileges and a compromised Hypervisor to induce DTE faults to bypass RMP checks in SEV-SNP, potentially resulting in a loss of guest integrity...

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...

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...

CVE-2026-10669 Xtensa MPU `arch_buffer_validate()` integer-overflow lets a user thread bypass syscall pointer validation

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...
