Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: gfs2: Fix for fiemap page faults In gfs2fiemap, we call iomapfiemap while holding the inode lock. This can lead to recursive locking if the fiemap buffer is memory-mapped to the same inode, and accessing it triggers a page...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: sched/rt: Fixed a race condition in the pushrttask function. Overview ======== When a CPU decides to call the pushrttask function and selects a task to be pushed onto another CPU’s runqueue, it will invoke the findlocklowestrq...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: powerpc/64s: Do not use DSISR for SLB faults. Since commit 46ddcb3950a2 “powerpc/mm: Show if a bad page fault on data is read or write”, we use pagefaultiswriteregs-dsisr in badpagefault to determine whether the fault is for a re...

InjectV: Modeling Fault Injection Attacks in RISC-V Simulation Environment

Fault Injection Attacks FIAs are a significant threat to hardware security, capable of compromising systems by inducing malicious faults in computation or storage. Evaluating resilience against such attacks is challenging due to the high cost, complexity, and limited availability of physical faul...

CVE-2026-46290

A flaw was found in the Linux kernel's x86/efi component. Due to changes in FPU softirq handling, the system incorrectly identifies normal task context as an interrupt context. This issue, when combined with buggy firmware that triggers page faults during EFI Extensible Firmware Interface runtime...

UBUNTU-CVE-2026-46290

In the Linux kernel, the following vulnerability has been resolved: x86/efi: Fix graceful fault handling after FPU softirq changes Since commit d02198550423 "x86/fpu: Improve crypto performance by making kernel-mode FPU reliably usable in softirqs", kernelfpubegin calls fpregslock which uses...

Model Poisoning against Federated Model Adaptation with Chain of Bit-Flips

Federated Learning FL allows a set of clients to collectively train a global model without sharing local training data. Giving the responsibility of the training to decentralized actors may lead to poisoning attacks: clients controlled by malicious third party potentially poison the training...

SUSE CVE-2026-43262

In the Linux kernel, the following vulnerability has been resolved: gfs2: fiemap page fault fix In gfs2fiemap, we are calling iomapfiemap while holding the inode glock. This can lead to recursive glock taking if the fiemap buffer is memory mapped to the same inode and accessing it triggers a page...

CVE-2026-43195

A flaw was found in the Linux kernel's drm/amdgpu graphics driver. This vulnerability arises from inadequate validation of user-provided queue sizes, which do not meet hardware requirements. An attacker could exploit this by supplying invalid queue size configurations, potentially leading to GPU...
