Use-after-free in Linux kernel SCSI imm delayed work teardown
CVE-2025-68324 is a use-after-free vulnerability in the Linux kernel's SCSI IMM parallel port host adapter driver. The driver initializes a delayed work item, imm_tq, in imm_attach() and schedules it from imm_queuecommand() to process SCSI commands. During device teardown in imm_detach(), the associated imm_struct object can be freed while the delayed work is still pending or executing. In that race window, the work handler imm_interrupt() dereferences the freed imm_struct via container_of(...), resulting in a use-after-free. The upstream fix adds disable_delayed_work_sync() in imm_detach() to synchronously cancel or drain the delayed work before deallocating the device structure.
