22
FAUCET Score

CVE-2009-1237 describes multiple memory leaks in Apple Mac OS X 10.5.6 and earlier, specifically within the XNU kernel, affecting both client and server versions. This vulnerability allows a local attacker to cause a denial of service by exhausting kernel memory through crafted SYS_add_profil or SYS___mac_getfsstat system calls. With a CVSS score of 4.9 (AV:L/AC:L/Au:N/C:N/I:N/A:C), it indicates low attack complexity and local access requirements, leading to a complete loss of availability. While not listed in CISA's KEV catalog and showing no community discussion or media coverage, proof-of-concept exploit code is publicly available on ExploitDB, though there's no indication of active exploitation.
