CVE-2026-90264

CVE-2026-90264 is a race condition in the Linux kernel's btrfs filesystem that can cause a kernel BUG/panic . The bug occurs when a direct IO finishes short: the file's isize is reverted, which skips the ordered extent (OE) wait during subsequent buffered writeback. This allows a new OE to be ins...

CVE-2026-90129

This Linux kernel vulnerability affects the virtio_balloon driver. A commit that added a generic virtio bus .shutdown handler (for reboot and kexec) breaks and resets all virtio devices, but virtio_balloon provides no .shutdown of its own, so its asynchronous work remains armed. Once the device i...
