erofs: fix interlaced ztailpacking pclusters<\/p>\n
On-disk sizes of interlaced pclusters should be block-aligned, and
\nztailpacking interlaced pclusters should be invalid at all.<\/p>\n
Currently, mkfs.erofs won’t generate any interlaced pcluster with
\nztailpacking enabled, so this doesn’t affect any existing valid
\nfilesystems.<\/p>\n
However, crafted images can contain invalid interlaced ztailpacking
\npclusters, resulting in an out-of-bounds read from a kmap’d page and
\ncopying irrelevant kernel memory into userspace-visible page cache.<\/p>\n","protected":false},"excerpt":{"rendered":"
