CVE-2011-1083

CVE-2011-1083 describes a denial-of-service vulnerability in the epoll implementation of Linux kernel versions 2.6.37.2 and earlier, affecting distributions like Red Hat and SUSE. A local attacker can exploit this by crafting an application that uses epoll_create and epoll_ctl system calls, leading to high CPU consumption. This vulnerability has a CVSS score of 4.9, indicating a low attack complexity and no authentication required, but it only allows for a denial of service. While not actively exploited in the wild and not on the CISA KEV catalog, a proof-of-concept exploit exists on ExploitDB, and there is no significant community discussion or media coverage.
