CVE-2019-15902

Disclosure Date: September 04, 2019 •
CVE-2019-15902 CVSS v3 Base Score: 5.6
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

A backporting error was discovered in the Linux stable/longterm kernel 4.4.x through 4.4.190, 4.9.x through 4.9.190, 4.14.x through 4.14.141, 4.19.x through 4.19.69, and 5.2.x through 5.2.11. Misuse of the upstream “x86/ptrace: Fix possible spectre-v1 in ptrace_get_debugreg()” commit reintroduced the Spectre vulnerability that it aimed to eliminate. This occurred because the backport process depends on cherry picking specific commits, and because two (correctly ordered) code lines were swapped.
