Published: 1/22/2024 Last updated: 8/10/2026 Reserved: 1/21/2024

A use-after-free flaw was found in the __ext4_remount in fs/ext4/super.c in ext4 in the Linux kernel. This flaw allows a local user to cause an information leak problem while freeing the old quota file names before a potential failure, leading to a use-after-free.
