CVE-2018-10882
First published: Fri Jun 29 2018(Updated: )
A flaw was found in the Linux kernel's ext4 file system. A local user can cause an out-of-bound write in in fs/jbd2/transaction.c code, which can lead to memory corruption. This can mean that the memory can be corrupted to create a denial of service, and a system crash or privilege escalation by unmounting a crafted ext4 filesystem image.
