Robur Albatross 1.0.0 through 2.x before 2.7.2 does not limit use of the ring buffer, leading to an albatross-console loop with no recognized termination condition. This is only exploitable by users who can send console subscription commands to unikernels that produce sufficient log output to fil...
CVE-2026-96609
Robur Albatross versions 1.0.0 through 2.x before 2.7.2 are vulnerable to a memory exhaustion denial of service. The albatross-console component fails to properly terminate when looping over its internal ring buffer (default 1024 lines). A user with permissions to send console subscription comman...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: Ring-Buffer: Sync-IRQ works before the buffer is destroyed. If something was written to the buffer just before its destruction, it may be possible—though not in a real system—to destroy the ringbuffer before the IRQ-related...
