CVE-2001-0268: Netbsd

High severity, CVSS 7.2. EPSS: 0.6% chance of exploitation in the next 30 days.

The i386_set_ldt system call in NetBSD 1.5 and earlier, and OpenBSD 2.8 and earlier, when the USER_LDT kernel option is enabled, does not validate a call gate target, which allows local users to gain root privileges by creating a segment call gate in the Local Descriptor Table (LDT) with a target that specifies an arbitrary kernel address.

Affected products

  • Netbsd Netbsd: up to and including 1.5
  • OpenBSD OpenBSD: up to and including 2.8
