Noroxi assessment
Priority: Monitor (action score 31/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.44% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: linux (Debian:12) 4.7.8-1; linux (Debian:7) 3.2.82-1; linux (Debian:8) 3.16.36-1+deb8u2.
Low priority for now. Upgrade to linux (Debian:12) 4.7.8-1; linux (Debian:7) 3.2.82-1; linux (Debian:8) 3.16.36-1+deb8u2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
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.
