Linux kernel elevation of privilege vulnerability (CNVD-2016-01042)

The Linux kernel is an open source, free operating system kernel originally done by Linus Torvalds. A security vulnerability exists in the kernel/ptrace.c file in Linux kernel 4.4.1 and earlier versions, which stems from the program's failure to properly handle uid and gid mappings. A local...

Medium: kernel

Issue Overview: The Linux kernel before 4.4.1 allows local users to bypass file-descriptor limits and cause a denial of service memory consumption by sending each descriptor over a UNIX socket before closing it, related to net/unix/afunix.c and net/unix/garbage.c. CVE-2013-4312 A race condition i...
