CVE-2008-3890

Status: ModifiedHigh (7.2)—

The kernel in FreeBSD 6.3 through 7.0 on amd64 platforms can make an extra swapgs call after a General Protection Fault (GPF), which allows local users to gain privileges by triggering a GPF during the kernel's return from (1) an interrupt, (2) a trap, or (3) a system call.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
