Ubuntu.comUB:CVE-2023-52616CVE-2023-52616
In the Linux kernel, the following vulnerability has been resolved: crypto:
lib/mpi - Fix unexpected pointer access in mpi_ec_init When the mpi_ec_ctx
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 mpi_ec_ctx is allocated with the
__GFP_ZERO flag. For example, this error will be triggered when calculating
the Za value for SM2 separately.
