Last modified

CVE-2009-0745 is a vulnerability of currently unknown severity. The ext4_group_add function in fs/ext4/resize.c in the Linux kernel 2.6.27 before 2.6.27.19 and 2.6.28 before 2.6.28.7 does not properly initialize the group descriptor during a resize (aka resize2fs) operation, which might allow local users to cause a denial of service (OOPS) by arranging for crafted values to be present in available memory.. EPSS estimates a 0.41% chance of exploitation in the next 30 days.
