CVE-2012-3375 (GCVE-0-2012-3375)

Vulnerability from cvelistv5 – Published: 2012-10-03 10:00 – Updated: 2024-08-06 20:05
VLAI
Summary
The epoll_ctl system call in fs/eventpoll.c in the Linux kernel before 3.2.24 does not properly handle ELOOP errors in EPOLL_CTL_ADD operations, which allows local users to cause a denial of service (file-descriptor consumption and system crash) via a crafted application that attempts to create a circular epoll dependency. NOTE: this vulnerability exists because of an incorrect fix for CVE-2011-1083.
Severity
No CVSS data available.
