DEBIAN-CVE-2025-68251
No affected components available
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().
