CVE-2026-63248

CVE-2026-63248 affects Eclipse Milo OPC UA server diagnostics nodes (versions 0.6.0–1.1.4). The diagnostics endpoint fails to enforce access authorization, allowing anonymous access over a None/None endpoint without a certificate, and enabling a trusted client with SignAndEncrypt to read security...

CVE-2026-63248

In Eclipse Milo versions 0.6.0 through 1.1.4, OPC UA server diagnostics nodes do not enforce access authorization. An anonymous client can enable diagnostics over a None/None endpoint without a certificate; with a trusted client application certificate over SignAndEncrypt, it can read security...

CVE-2026-64561

CVE-2026-64561 is a Linux kernel vulnerability in KVM/x86 shadow MMU where, after reclaiming shadow MMU pages, an invalid/obsolete root could be created and then mapped. If a stale root is zapped and a child shadow page inherits that role, new child pages can be created as invalid, violating KVM’...

CVE-2026-64561 KVM: x86: Check for invalid/obsolete root *after* making MMU pages available

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Check for invalid/obsolete root after making MMU pages available Check for a "stale" page fault, i.e. for an invalid and/or obsolete root, after making MMU pages available for the shadow MMU. If reclaiming shadow pages...

kernel: KVM: x86: Fix shadow paging use-after-free due to unexpected GFN

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine x86 shadow paging mechanism. This use-after-free vulnerability arises from incorrect handling of Guest Frame Numbers GFNs when guest page tables are modified. A local attacker with control over a guest virtual machine could...

CVE-2022-4994

CVE-2022-4994 concerns a Linux kernel KVM/x86 issue where the fast IN path for in-kernel PIO was adjusted. The change routes fast PIO through __emulator_pio_in() directly instead of bouncing via emulator_pio_in(), since __emulator_pio_in() now fills the required value and vcpu->arch.pio.count ...

CVE-2022-4994

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: wean fast IN from emulatorpioin Use emulatorpioin directly for fast PIO instead of bouncing through emulatorpioin now that emulatorpioin fills "val" when handling in-kernel PIO. vcpu-arch.pio.count is guaranteed to be...

SUSE-SU-2026:22981-1 Security update for the Linux Kernel (Live Patch 13 for SUSE Linux Enterprise 16)

This update for the SUSE Linux Enterprise Kernel 6.12.0-160000.34.1 fixes various security issues: The following security issues were fixed: - CVE-2026-53359: KVM: x86: Fix shadow paging use-after-free due to unexpected role bsc1270060. - CVE-2026-53366: ipv4: account for fraggap on the paged...

CVE-2026-64286

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for arm64 architecture. The flushhypvcpu function, responsible for copying the host virtual CPU vCPU context, does not properly clear a specific internal pointer hyprunningvcpu. This oversight allows a host to provide a value...

PT-2026-66444

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the KVM x86 module where the emulator pio in function was used as a bounce for fast PIO. The fix involves using emulator pio in directly for fast PIO, as emulator pio ...

The vulnerability of the `init_amd_zen1()` function in the `arch/x86/kernel/cpu/amd.c` module, which is part of the Linux operating system’s kernel support for x86 platforms, allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the initamdzen1 function in the arch/x86/kernel/cpu/amd.c module, which is part of the Linux operating system’s kernel support for x86 platforms, is related to incorrect inter-process boundary removal of critical data. Exploiting this vulnerability could allow an attacker to...

CVE-2026-64484

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture es1938 sound driver. This vulnerability arises when a memory allocation failure causes the sndctlnew1 function to return a null value. The sndes1938mixer function then attempts to use this null value without proper...

CVE-2026-64559

In the Linux kernel, the following vulnerability has been resolved: s390/pkey: Check length in PKEYVERIFYPROTK ioctl Explicitly check the buffer length request structure provided by user-space and fail, if it exceeds the buffer size...
