CVE-2023-53569 Details
Description
In the Linux kernel, the following vulnerability has been resolved: ext2: Check block size validity during mount Check that log of block size stored in the superblock has sensible value. Otherwise the shift computing the block size can overflow leading to undefined behavior.
A vulnerability exists in the Linux kernel's ext2 file system module, specifically in the handling of block size during the mounting process. The issue arises because the log of the block size stored in the superblock is not properly validated. If an invalid log block size is encountered, it can cause an overflow when calculating the block size, leading to undefined behavior. This vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for upgrading the kernel can be found in the official Linux kernel documentation.
