Astra Linux – Vulnerability in amd64-microcode

Improper or unexpected behavior of the INVD instruction in some AMD CPUs may allow an attacker with a malicious hypervisor to influence the cache line write-back behavior of the CPU, resulting in a potential loss of integrity of the guest virtual machine VM memory...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: soc: qcom: cmd-db: Maps shared memory as WC, not WB. Linux does not write to the cmd-db region. This memory region is protected from writing by XPU. XPU may sometimes falsely detect a clean cache eviction as a “write” to the...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.18 contains security vulnerabilities. These vulnerabilities stem from the cachereplay function in dm-pcache, as well as the write-back worker threads and GC worker threads. In these functions, the length of the tail read from kset is determined by PCACHESEGSIZE - segoff...

In the Linux kernel, the following vulnerability has been resolved: btrfs: do not strictly require dirty metadata threshold for metadata writepages BUG There is an internal report that over 1000 processes are waiting at the ioscheduletimeout of balancedirtypages, causing a system hang and trigger...

CVE-2025-68807

A race condition flaw was found in the Linux kernel's block layer writeback throttling WBT initialization. When enabling WBT during an I/O elevator change, a race with concurrent I/O submission can cause the WBT inflight counter to become negative. This leads to tasks hanging indefinitely in...

Linux Kernel Security Vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from updating the compression context during a write-back, which could result in a divide-by-zero error...

Linux Kernel Security Vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that stems from not waiting for a page write-back to complete, which could result in multiple write-backs of the same page and...

EUVD-2025-150393

In the Linux kernel, the following vulnerability has been resolved: x86/kvm: Force legacy PCI hole to UC when overriding MTRRs for TDX/SNP When running as an SNP or TDX guest under KVM, force the legacy PCI hole, i.e. memory between Top of Lower Usable DRAM and 4GiB, to be mapped as UC via a forc...

kernel: soc: qcom: cmd-db: Map shared memory as WC, not WB

A flaw was found in the Linux kernel. Incorrect memory mapping of the cmd-db shared memory region as Write-Back WB instead of Write-Combine WC can lead to a Denial of Service DoS. When a hypervisor other than the Qualcomm Hypervisor is in use, the eXtended Protection Unit XPU may falsely detect...
