swapfile corruption

About this tag
Swapfile corruption refers to data integrity issues that arise when a swapfile's physical block mapping becomes incorrect, often due to filesystem bugs. On WindowsForum.com, discussions cover vulnerabilities like CVE-2026-23233, a Linux kernel flaw in the F2FS filesystem that can cause the wrong physical blocks to be mapped for a swapfile, leading to data corruption, boot hangs, or dm-verity failures. This is a narrow but serious edge case involving fragmented swapfiles and extent handling. While the tag focuses on Linux kernel issues, it is relevant to users managing swapfiles on systems using F2FS, particularly those concerned with data integrity and system stability.
