Severity ?
Summary
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.
