CVE-2025-68251:
Linux Kernel vulnerability analysis and mitigation
In the Linux kernel, the following vulnerability has been resolved:
erofs: avoid infinite loops due to corrupted subpage compact indexes
Robert reported an infinite loop observed by two crafted images.
The root cause is that clusterofs can be larger than lclustersize
for !NONHEAD lclusters in corrupted subpage compact indexes, e.g.:
blocksize = lclustersize = 512 lcn = 6 clusterofs = 515
Move the corresponding check for full compress indexes to
z_erofs_load_lcluster_from_disk() to also cover subpage compact
compress indexes.
It also fixes the position of m->type >= Z_EROFS_LCLUSTER_TYPE_MAX
check, since it should be placed right after
z_erofs_load_{compact,full}_lcluster().
