CVE-2025-38697
In the Linux kernel, the following vulnerability has been resolved: jfs: upper bound check of tree index in dbAllocAG When computing the tree index in dbAllocAG, we never check if we are out of bounds realative to the size of the stree.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.18%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
