FKIE_CVE-2015-8569

Vulnerability from fkie_nvd - Published: 2015-12-28 11:59 - Updated: 2026-06-17 00:34
Severity
2.3 (Low) - CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N
Summary
The (1) pptp_bind and (2) pptp_connect functions in drivers/net/ppp/pptp.c in the Linux kernel through 4.3.3 do not verify an address length, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism via a crafted application.
