Last modified

CVE-2009-1238 is a vulnerability of currently unknown severity. Race condition in the HFS vfs sysctl interface in XNU 1228.8.20 and earlier on Apple Mac OS X 10.5.6 and earlier allows local users to cause a denial of service (kernel memory corruption) by simultaneously executing the same HFS_SET_PKG_EXTENSIONS code path in multiple threads, which is problematic because of lack of mutex locking for an unspecified global variable.. EPSS estimates a 0.62% chance of exploitation in the next 30 days.
