| 2 | * Fix a null pointer dereference when mbedtls_mpi_exp_mod() was called with | ||||
| 3 | A=0 represented with 0 limbs. Up to and including Mbed TLS 2.26, this bug | ||||
| 4 | could not be triggered by code that constructed A with one of the | ||||
| 5 | mbedtls_mpi_read_xxx functions (including in particular TLS code) since | ||||
| 6 | those always built an mpi object with at least one limb. | ||||
| 7 | Credit to OSS-Fuzz. Fixes #4641. | ||||
