- Details

In the Linux kernel, the following vulnerability has been resolved:
crypto: lib/mpi - Fix unexpected pointer access in mpiecinit
When the mpiecctx structure is initialized, some fields are not cleared, causing a crash when referencing the field when the structure was released. Initially, this issue was ignored because memory for mpiecctx is allocated with the _GFPZERO flag. For example, this error will be triggered when calculating the Za value for SM2 separately.
