The do_task_stat function in fs/proc/array.c in the Linux kernel before 2.6.39-rc1 does not perform an expected uid check, which makes it easier for local users to defeat the ASLR protection mechanism by reading the start_code and end_code fields in the /proc/#####/stat file for a process executing a PIE binary.

Security readout for executives and security teams

CVE-2011-0726 is a Linux kernel information leak that can weaken ASLR. A local user could read process memory layout fields from /proc for PIE binaries, making another exploit easier. It is not described as a remote compromise or standalone privilege escalation in the provided sources. Exposure is most relevant to older Linux kernels or vendor kernels lacking the referenced backport. Systems with local shell users, multi-tenant workloads, or untrusted local processes have higher practical relevance than single-purpose systems with no local user access. Treat this as a legacy local hardening issue. It is not presented as internet-exploitable, but it can lower the cost of exploiting another local vulnerability. Prioritize remediation where old Linux kernels support shared users, hosting, build systems, or untrusted workloads. Mitigation focus: Update to a kernel containing the proc start_code/end_code protection patch.; Apply supported vendor kernel advisories, including relevant distribution backports.; Check vendor guidance for embedded or appliance products using affected kernels..
