CVE-2026-45899 Details
Description
In the Linux kernel, the following vulnerability has been resolved: ext4: drop extent cache when splitting extent fails When the split extent fails, we might leave some extents still being processed and return an error directly, which will result in stale extent entries remaining in the extent status tree. So drop all of the remaining potentially stale extents if the splitting fails.
A vulnerability exists in the Linux kernel's ext4 file system component, specifically in the handling of extent splitting operations. When an error occurs during the splitting process, some extents may remain in a 'processing' state, leading to stale entries in the extent status tree. This issue can cause inconsistencies in how extents are managed, potentially affecting file system performance and reliability.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for downloading the patched kernel can be found on the official Linux kernel website.
