Last modified Jun 16, 2026

CVE-2010-4210 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. The pfs_getextattr function in FreeBSD 7.x before 7.3-RELEASE and 8.x before 8.0-RC1 unlocks a mutex that was not previously locked, which allows local users to cause a denial of service (kernel panic), overwrite arbitrary memory locations, and possibly execute arbitrary code via vectors related to opening a file on a file system that uses pseudofs.. EPSS estimates a 1.13% chance of exploitation in the next 30 days.
