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.
Does this matter?
Lower severity and a low EPSS score (0.20%). Track it; it rarely justifies an emergency change on its own.
