Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the initialization of the
mpi ec ctx structure in the Linux kernel's crypto library. When this structure is initialized, some fields are not cleared, causing a crash when referencing the field after the structure has been released. This error can be triggered, for example, when calculating the Za value for SM2 separately. The memory for mpi ec ctx is allocated with the GFP ZERO flag, which initially led to this issue being ignored.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
