CVE-2005-1263

CVE-2005-1263 describes a local buffer overflow vulnerability in the elf_core_dump function of the Linux kernel (versions 2.x.x, 2.4.x, and 2.6.x). This flaw allows local users to execute arbitrary code by crafting a malicious ELF binary that causes a negative length argument to bypass a signed integer comparison. With a CVSS score of 7.2, this vulnerability is considered high severity, enabling complete compromise of confidentiality, integrity, and availability from a local attack with low complexity. While there is no evidence of active exploitation, a proof-of-concept exploit exists on ExploitDB, though it has garnered minimal community discussion or media coverage.
