CVSS v3.1
Official Description
The NFSv4 Server module in the kernel in Sun Solaris 10, and OpenSolaris before snv_111, allow local users to cause a denial of service (infinite loop and system hang) by accessing an hsfs filesystem that is shared through NFSv4, related to the rfs4_op_readdir function.
Technical Analysis
CVE-2009-0870 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
