CVE-2026-93816 in Linux
Summary
by MITRE • 09/24/2026
In the Linux kernel, the following vulnerability has been resolved:
f2fs: validate inline dentry name lengths before conversion
Inline dentry conversion copies names out of the inline dentry area before checking that each recorded name length fits in the available filename slots.
A corrupted image can therefore make the conversion path read past the inline filename storage while building the regular dentry block.
Validate each inline dentry name length against the inline filename area before copying it.
