Description
In the Linux kernel, the following vulnerability has been resolved: NFSv4/pNFS: Clear NFS_INO_LAYOUTCOMMIT in pnfs_mark_layout_stateid_invalid Fixes a crash when layout is null during this call stack: write_inode -> nfs4_write_inode -> pnfs_layoutcommit_inode pnfs_set_layoutcommit relies on the lseg refcount to keep the layout around. Need to clear NFS_INO_LAYOUTCOMMIT otherwise we might attempt to reference a null layout.
