Detailsinfo

A vulnerability was found in Linux Kernel up to 6.1.102/6.6.43/6.10.2. It has been classified as problematic. Affected is the function log_replay of the component NTFS File Handler. The impact remains unknown. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Update log->page_{mask,bits} if log->page_size changed If an NTFS file system is mounted to another system with different PAGE_SIZE from the original system, log->page_size will change in log_replay(), but log->page_{mask,bits} don't change correspondingly. This will cause a panic because "u32 bytes = log->page_size - page_off" will get a negative value in the later read_log_page().

The advisory is shared for download at git.kernel.org. This vulnerability is traded as CVE-2024-42299 since 07/30/2024. There are known technical details, but no exploit is available.
