Bugzilla:
1377330: CVE-2016-7425 kernel: SCSI arcmsr driver: Buffer overflow in arcmsr_iop_message_xfer()
A heap-buffer overflow vulnerability was found in the arcmsr_iop_message_xfer() function in 'drivers/scsi/arcmsr/arcmsr_hba.c' file in the Linux kernel through 4.8.2. The function does not restrict a certain length field, which allows local users to gain privileges or cause a denial of service via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code. This can potentially cause kernel heap corruption and arbitrary kernel code execution.
