What to Know

In the Linux kernel, the following vulnerability has been resolved:

scsi: sd: Fix error handling in sd_probe() after large pool creation failure

After device_add(&sdkp->disk_dev) succeeds, sd_large_pool_create()

failure must unregister disk_dev and let scsi_disk_release() free

sdkp. Going through out_free_index kfree()s an already registered device

and leaks the sysfs entry. (NVD)

What to Do

Monitor Linux's web page for any future patch releases.
