CVE-2009-2857 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. The kernel in Sun Solaris 8, 9, and 10, and OpenSolaris before snv_103, does not properly handle interaction between the filesystem and virtual-memory implementations, which allows local users to cause a denial of service (deadlock and system halt) via vectors involving mmap and write operations on the same file.. EPSS estimates a 0.27% chance of exploitation in the next 30 days.
