CVE-2010-0453: n/a vulnerability

CVE-2010-0453: The ucode_ioctl function in intel/io/ucode_drv.c in Sun Solaris 10 and OpenSolaris snv_69 through snv_133,...

The ucode_ioctl function in intel/io/ucode_drv.c in Sun Solaris 10 and OpenSolaris snv_69 through snv_133, when running on x86 architectures, allows local users to cause a denial of service (panic) via a request with a 0 size value to the UCODE_GET_VERSION IOCTL, which triggers a NULL pointer dereference in the ucode_get_rev function, related to retrieval of the microcode revision.

Security readout for executives and security teams

This is a local denial-of-service flaw in Solaris on x86 systems. A user with local access could trigger a kernel panic, causing system downtime. The bundle does not provide CVSS scoring or evidence of active exploitation. Exposure is most likely on legacy Solaris 10 or OpenSolaris x86 systems that still allow local shell, application, or multi-user access. Non-x86 systems are not identified as affected in the provided description. Treat as a legacy availability risk. It is not presented as remotely exploitable, but production Solaris x86 systems with local users could be crashed and should be patched or retired. Mitigation focus: Identify Solaris 10 and OpenSolaris x86 hosts in inventory.; Review Oracle CPU April 2010 and SunSolve guidance for applicable fixes.; Prioritize patching shared, production, or privileged multi-user Solaris systems..
