Last modified

CVE-2009-0748 is a vulnerability of currently unknown severity. The ext4_fill_super function in fs/ext4/super.c in the Linux kernel 2.6.27 before 2.6.27.19 and 2.6.28 before 2.6.28.7 does not validate the superblock configuration, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) by attempting to mount a crafted ext4 filesystem.. EPSS estimates a 0.51% chance of exploitation in the next 30 days.
