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.

Security readout for executives and security teams

This is a local privilege escalation issue in older i386 NetBSD and OpenBSD systems. If a specific kernel option, USER_LDT, is enabled, a local user may be able to gain root privileges by abusing insufficient validation in a system call. Exposure appears limited to legacy i386 NetBSD 1.5 and earlier, and OpenBSD 2.8 and earlier, with USER_LDT enabled. The provided CVE data does not identify modern affected products or complete CPE coverage. Treat this as high priority only for legacy systems with local users. It is not presented as remotely exploitable, but successful abuse can give an unprivileged user full root control. Mitigation focus: Check NetBSD and OpenBSD advisories for vendor-supported fixes or configuration guidance.; Disable USER_LDT where it is not operationally required.; Upgrade unsupported legacy systems to maintained operating system releases..
