How to fix?

There is no fixed version for RHEL:10 rv.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rv package and not the rv package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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().
