CVE-2018-10882
A local user can cause an out-of-bound write in in fs/jbd2/transaction.c code, a denial of service, and a system crash by unmounting a crafted ext4 filesystem image.
Does this matter?
Lower severity and a low EPSS score (0.72%). 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 write in in fs/jbd2/transaction.c code, a denial of service, and a system crash by unmounting a crafted ext4 filesystem image.
