HIGHCVSS 7.8/10EPSS 0.43%

Last modified

CVE-2016-7425 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel through 4.8.2 does not restrict a certain length field, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code.. EPSS estimates a 0.43% chance of exploitation in the next 30 days.
