Description
The vulnerability allows a local attacker to cause DoS condition on the target system.
The vulnerability exists in the sr_do_ioctl function, as defined in the drivers/scsi/sr_ioctl.c source code file due to differing buffer sizes in the CDROM layer and the SCSI layer. A local attacker can submit specially crafted input, trigger a stack-based overflow and cause the system to crash.
