What is CVE-2022-49708?

A vulnerability in the Linux kernel's EXT4 filesystem can cause unexpected behavior due to a bug in the buffer management mechanism. This issue arises when specific commands lead to a miscalculation of disk space during file operations. The problem is triggered upon invoking functions related to writing and managing disk blocks, particularly when the calculated extent exceeds expected limits. Such scenarios could compromise data integrity and lead to system instability if exploited. Reproducing the issue involves specific commands that manipulate disk space and filesystem structures, potentially affecting various users operating under high-load scenarios.
