CVE-2023-52472 Information

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.
