CVE-2025-37740

Estado: AnalizadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

jfs: add sanity check for agwidth in dbMount

The width in dmapctl of the AG is zero, it trigger a divide error when calculating the control page level in dbAllocAG.

To avoid this issue, add a check for agwidth in dbAllocAG.
