Description

In the Linux kernel, the following vulnerability has been resolved: crypto: rsa - add a check for allocation failure Static checkers insist that the mpi_alloc() allocation can fail so add a check to prevent a NULL dereference. Small allocations like this can't actually fail in current kernels, but adding a check is very simple and makes the static checkers happy.

Affected products

• Linux kernel: from 6.5.0 before 6.6.14; from 6.7.0 before 6.7.2 — fixed in 6.6.14, 6.7.2

How to fix

Upgrade to a fixed version: Linux kernel 6.6.14, 6.7.2. Check the vendor advisory for mitigations.
