CVE-2026-99086

A vulnerability exists in the Linux kernel within the dm-integrity component. The dm_integrity_resume() function re-reads the superblock from the device without validation, while in-memory structures are sized based on the validated superblock read during the constructor. An attacker can modify t...

CVE-2026-99085

The Linux kernel contains a vulnerability in sched_ext where a CPU hotplug hang can occur if a dying CPU's tasks are held by the BPF scheduler . The issue arises because tasks on a user DSQ are still counted on the runqueue (rq), but an inactive CPU stops calling ops.dispatch(), preventing tasks ...
