The compat_alloc_user_space functions in include/asm/compat.h files in the Linux kernel before 2.6.36-rc4-git2 on 64-bit platforms do not properly allocate the userspace memory required for the 32-bit compatibility layer, which allows local users to gain privileges by leveraging the ability of the compat_mc_getsockopt function (aka the MCAST_MSFILTER getsockopt support) to control a certain length value, related to a "stack pointer underflow" issue, as exploited in the wild in September 2010.

Security readout for executives and security teams

CVE-2010-3081 is an old Linux kernel flaw that can let a local user become root on affected 64-bit systems. It matters most for legacy Linux or VMware ESX service-console environments where untrusted users, shared hosting, or compromised low-privilege accounts exist. Exposure is likely limited to legacy 64-bit Linux kernels before 2.6.36-rc4-git2 and vendor products that shipped vulnerable kernels, including advisories from Red Hat, SUSE, Mandriva, and VMware ESX service-console updates. The bundle does not provide a complete affected-product matrix. Prioritize remediation where old Linux systems still support business operations or host multiple users. This is not a remote network bug, but a single compromised local account could become full system control on affected hosts. Mitigation focus: Inventory 64-bit Linux systems running kernels before 2.6.36-rc4-git2.; Apply the relevant vendor kernel updates from Red Hat, SUSE, Mandriva, VMware, or your distributor.; Prioritize shared, multi-user, hosting, and legacy virtualization management systems..
