zfs_acl_node_alloc allocates an uninitialized data buffer, but upstack zfs_acl_chmod only partially initializes it. KMSAN reported that this memory remained uninitialized at the point when it was read by lzjb_compress, which suggests a possible kernel memory disclosure bug. The full KMSAN warning may be found in the PR. https://github.com/openzfs/zfs/pull/16511 Signed-off-by: Alan Somers <asomers@gmail.com> Sponsored by: Axcient Reviewed-by: Alexander Motin <mav@FreeBSD.org> Reviewed-by: Tony Hutter <hutter2@llnl.gov>
