- Summary
- nvme: nvme-fc: Ensure ->ioerr_work is cancelled in nvme_fc_delete_ctrl()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
nvme: nvme-fc: Ensure ->ioerrwork is cancelled in nvmefcdeletectrl()
nvmefcdeleteassocation() waits for pending I/O to complete before returning, and an error can cause ->ioerrwork to be queued after cancelworksync() had been called. Move the call to cancelworksync() to be after nvmefcdeleteassociation() to ensure ->ioerrwork is not running when the nvmefcctrl object is freed. Otherwise the following can occur:
