CVE-2018-10881
A local user can cause an out-of-bound access in ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image.
Does this matter?
Lower severity and a low EPSS score (0.77%). Track it; it rarely justifies an emergency change on its own.
Description
A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bound access in ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image.
