CVE-2026-43075

A flaw was found in the Linux kernel's ocfs2 filesystem component. This vulnerability allows a local attacker, by mounting a specially crafted and corrupted ocfs2 filesystem on a loop device, to trigger an out-of-bounds write. This occurs because the system incorrectly trusts the idcount field fr...

CVE-2026-43076

A flaw was found in the ocfs2 filesystem module of the Linux kernel. This vulnerability occurs when the system attempts to read an inode from a corrupted filesystem, where the inline data size is not properly validated. This can lead to a use-after-free condition, potentially allowing a local...

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...
