The arc4random function in the kernel in FreeBSD 6.3 through 7.1 does not have a proper entropy source for a short time period immediately after boot, which makes it easier for attackers to predict the function's return values and conduct certain attacks against the GEOM framework and various network protocols, related to the Yarrow random number generator.

Exploit prediction (EPSS)

0.32% probability of exploitation in the next 30 days, higher than 25% of all scored CVEs.
