Last modified
CVE-2023-53569 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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.. EPSS estimates a 0.14% chance of exploitation in the next 30 days.
