CVE-2026-53124

CVE-2026-53124 concerns the Linux kernel ublk subsystem. A per-IO canceled flag incorrectly remains set if a ublk server dies during device recovery before all IOs are fetched, causing cancellation of fetch commands to potentially never complete. This leaves outstanding I/O and can lead to resour...
