Description

In the Linux kernel, the following vulnerability has been resolved: scsi: elx: efct: Fix refcount leak in efct_hw_io_abort() When efct_hw_reqtag_alloc() fails in efct_hw_io_abort(), the error path returns -ENOSPC without releasing the reference obtained via kref_get_unless_zero() earlier in the function. All other error paths correctly drop the reference. This causes a permanent reference leak on the io_to_abort object. Additionally, the abort_in_progress flag is left set to true on this path, which means future abort attempts for the same I/O will immediately return -EINPROGRESS even though the abort was never submitted, effectively blocking recovery. Fix this by adding the missing kref_put() call and reset abort_in_progress to false, matching the cleanup done in the efct_hw_wq_write() failure path below.
