CVE-2018-12088

S3QL before 2.27 mishandles checksumming, and consequently allows replay attacks in which an attacker who controls the backend can present old versions of the filesystem metadata database as up-to-date, temporarily inject zero-valued bytes into files, or temporarily hide parts of files. This is...

kernel: ext4: fix undefined behavior in bit shift for ext4_check_flag_values

A vulnerability was identified in the Linux kernel's ext4 filesystem implementation due to a flaw in how it processes filesystem metadata. An attacker with local privileges could create a malicious ext4 filesystem image to trigger this issue. When the system attempts to mount this malicious image...

UBUNTU-CVE-2025-1125

When reading data from a hfs filesystem, grub's hfs filesystem module uses user-controlled parameters from the filesystem metadata to calculate the internal buffers size, however it misses to properly check for integer overflows. A maliciouly crafted filesystem may lead some of those buffer size...
