CVE-2026-53123

The CVE relates to the Linux kernel md subsystem during raid456 reshape. If a direct IO operation crosses the reshape boundary, raid5_make_request() can sleep while an active_io reference is held. If userspace freezes reshape and triggers mddev_suspend(), the code kills active_io and waits for in...

ALPINE-CVE-2026-42487

HVM guest I/O port accesses are subject to either emulation or at least translation. Translations are managed by the device model via XENDOMCTLioportmapping, and hence the linked list used may changed at any time. Traversal of those lists while handling guest I/O port accesses therefore needs...

CVE-2026-54533 vantage6 node has an Improper Access Control issue

vantage6 is an open-source infrastructure for privacy preserving analysis. Prior to version 5.0.0, malicious algorithms can potentially access other algorithms input and output files. Version 5.0.0 fixes the issue. As a workaround, verify and restrict the algorithm containers that are allowed to...

CVE-2026-8049

The CVE-2026-8049 issue affects SignalRGB’s Windows kernel driver, SignalIo.sys, in versions prior to 1.3.7.0. The device object (.SignalIo) is created without an explicit SDDL security descriptor and without FILE_DEVICE_SECURE_OPEN, resulting in overly permissive default access. This permits any...
