The mpi_powm function in lib/mpi/mpi-pow.c in the Linux kernel through 4.8.11 does not ensure that memory is allocated for limb data, which allows local users to cause a denial of service (stack memory corruption and panic) via an add_key system call for an RSA key with a zero exponent.

Security readout for executives and security teams

CVE-2016-8650 is a local denial-of-service flaw in the Linux kernel key subsystem. A local user can trigger stack memory corruption and a kernel panic using a malformed RSA key operation, potentially crashing the system. Exposure is most relevant to Linux systems running vulnerable kernel versions through 4.8.11, especially shared servers, developer hosts, and systems where untrusted local users or workloads can access kernel keyring functionality. Treat as a reliability and availability risk, not a remote breach indicator. Patch in normal kernel maintenance, with faster action for multi-user or workload-hosting systems. Mitigation focus: Apply vendor kernel updates that include the upstream Linux fix.; Use Red Hat or platform-specific advisories to identify fixed package versions.; Upgrade kernels beyond vulnerable versions where vendor support allows..
