USN-8547-2: Linux kernel (Azure FIPS) vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - RISC-V architecture; - Cryptographic API; - InfiniBand drivers; - IOMMU subsystem; - Network drivers; -...

vpod v0.5.0

Vpod Getting Started • Documentation • Issues • Contributing What is a vpod ? A vpod is a lightweight, portable sandbox that gives an untrusted process an instant Linux environment. It uses a RISC‑V architecture and runs entirely inside WebAssembly. Fast startup : Boot in under a second. Portable...

[SECURITY] Fedora 43 Update: systemd-258.10-1.fc43

systemd is a system and service manager that runs as PID 1 and starts the rest of the system. It provides aggressive parallelization capabilities, uses sock et and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux control groups,...

CVE-2026-64524

The CVE-2026-64524 issue affects the Linux kernel's DRM Hyper-V driver. A SYNTHVID_RESOLUTION_RESPONSE with resolution_count > 64 could bypass the bound check on the supported_resolution array, potentially leading to out-of-bounds behavior during parsing. The fix binds resolution_count to the ...

SUSE CVE-2026-64247

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: hyper-v: Bound the bank index when querying sparse banks When checking if a VP ID is included in a sparse bank set, explicitly check that the ID can actually be contained in a sparse bank the TLFS allows for a maximum o...

PT-2026-64758

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the drm/hyperv component where the hyperv receive sub function processes VMBus packets without verifying the actual number of bytes written by the host into hv-recv bu...

PT-2026-64529

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the crypto ccp component where the system improperly initializes SNP for the ioctlSNP VLEK LOAD function. A userspace process could potentially trigger this code path...

CVE-2026-64247

CVE-2026-64247 concerns the Linux kernel KVM code for x86 with hyper-v virtualization. The issue arises when checking if a VP ID is in a sparse bank set: the VP ID could be copied without bounds checking, risking an out-of-bounds read when testing the sparse bank and potentially triggering an unn...
