CVE-2026-43076 ocfs2: validate inline data i_size during inode read

In the Linux kernel, the following vulnerability has been resolved: ocfs2: validate inline data isize during inode read When reading an inode from disk, ocfs2validateinodeblock performs various sanity checks but does not validate the size of inline data. If the filesystem is corrupted, an inode's...

CVE-2026-43076

The vulnerability CVE-2026-43076 affects the ocfs2 filesystem in the Linux kernel. When reading an inode from disk, ocfs2_validate_inode_block() did not validate the i_size of inline data against the inline data capacity (id_count). A corrupted filesystem could make i_size exceed id_count, causin...

CVE-2026-43075 ocfs2: fix out-of-bounds write in ocfs2_write_end_inline

In the Linux kernel, the following vulnerability has been resolved: ocfs2: fix out-of-bounds write in ocfs2writeendinline KASAN reports a use-after-free write of 4086 bytes in ocfs2writeendinline, called from ocfs2writeendnolock during a copyfilerange splice fallback on a corrupted ocfs2 filesyst...

CVE-2026-43075

The CVE-2026-43075 issue affects the Linux kernel’s ocfs2 filesystem code. A corrupted ocfs2 filesystem mounted on a loop device could trigger an out-of-bounds write in ocfs2_write_end_inline during a copy_file_range splice fallback, caused by trusting on-disk id_count to fit inline data. The roo...
