CVE-2026-46050

A flaw was found in the Linux kernel's md/raid10 component. A local user performing a check operation while an application is doing nowait I/O Input/Output on the same array can trigger a deadlock. This occurs because the nrpending value underflows, causing the md resync thread to become stuck...

CVE-2026-46050

CVE-2026-46050 affects the Linux kernel md/raid10 code. A deadlock can occur when a check operation runs concurrently with NOWAIT I/O on the same array: barrier raises, normal requests block, nr_pending underflows, and the md resync thread may stall waiting for nr_pending == 0. The root cause inv...
