CVE-2023-53450

MEDIUM

Linux Kernel 2.6.25-4.14.315 - Reachable Assertion via Superblock Manipulation

Title source: llm
STIX 2.1

Description

In the Linux kernel, the following vulnerability has been resolved: ext4: remove a BUG_ON in ext4_mb_release_group_pa() If a malicious fuzzer overwrites the ext4 superblock while it is mounted such that the s_first_data_block is set to a very large number, the calculation of the block group can underflow, and trigger a BUG_ON check. Change this to be an ext4_warning so that we don't crash the kernel.
