CVE-2009-1235 is a local privilege escalation vulnerability affecting Apple Mac OS X 10.5.6 and earlier, specifically within the XNU kernel's HFS IOCTL handler. An attacker can exploit this by attaching a specially crafted HFS+ disk image and using HFS_GET_BOOT_INFO fcntl calls to overwrite kernel memory, thereby gaining root privileges. With a CVSS score of 7.2, this vulnerability is considered high severity due to its low attack complexity and complete impact on confidentiality, integrity, and availability. While not listed in CISA's KEV catalog, public exploit code exists on ExploitDB, though there is no evidence of active exploitation or significant community discussion.
