CVE-2015-4170 describes a race condition in the Linux kernel's tty subsystem (specifically, the ldsem_cmpxchg function in drivers/tty/tty_ldsem.c) affecting versions before 3.13-rc4-next-20131218, including Red Hat distributions. This flaw allows a local attacker to trigger a denial of service by creating a new tty thread during the shutdown of an existing one, leading to a deadlock. Rated Medium severity (CVSS 4.7), exploitation requires high attack complexity and user interaction, but can result in high availability impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage for this vulnerability.
