USB storage hang via ignored allocation flags
Published Sep 24, 2026 · Updated Sep 24, 2026
Deadlock in Linux before 6.12.111 and before 6.18.53 can hang USB storage recovery during a root-hub device reset. The rh_call_control() path replaces a caller-supplied GFP_NOIO allocation constraint with GFP_KERNEL while processing a root-hub control transfer. A SCSI error-handler reset or resume can therefore trigger further I/O reclamation through the same storage stack and deadlock it, leaving storage recovery hung.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
