Description

In the Linux kernel, the following vulnerability has been resolved: erofs: fix interlaced ztailpacking pclusters On-disk sizes of interlaced pclusters should be block-aligned, and ztailpacking interlaced pclusters should be invalid at all. Currently, mkfs.erofs won't generate any interlaced pcluster with ztailpacking enabled, so this doesn't affect any existing valid filesystems. However, crafted images can contain invalid interlaced ztailpacking pclusters, resulting in an out-of-bounds read from a kmap'd page and copying irrelevant kernel memory into userspace-visible page cache.
