- Summary
- crypto: rsa - add a check for allocation failure
- Details
-
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.
