CVE-2017-7482

CVE-2017-7482 is a memory corruption vulnerability in the Linux kernel (before version 4.12) affecting Kerberos 5 ticket decoding within the RXRPC keys, specifically impacting Debian and Red Hat Linux distributions. This flaw, stemming from an incorrect field size assumption, could cause a size-remaining variable to wrap and a data pointer to exceed buffer boundaries. Rated as High severity (CVSS 7.8), it presents a local attack vector with low complexity, potentially leading to privilege escalation, confidentiality, integrity, and availability impacts. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
