Security readout for executives and security teams
CVE-2011-1090 is a Linux kernel denial-of-service flaw in NFSv4 ACL handling. A local user could trigger a kernel panic by attempting to set a crafted ACL. The issue is old and tied to kernels before 2.6.38, but legacy systems or vendor kernels without the backported fix may still matter. Exposure is most plausible on legacy Linux systems, appliances, or vendor-supported kernels derived from pre-2.6.38 code with NFSv4 ACL functionality. The source bundle does not provide a complete affected product matrix, so distribution-specific backport status must be checked against vendor advisories. Treat this as a legacy availability risk. It is not presented as active exploitation or remote code execution, but vulnerable multi-user or NFS-dependent systems could suffer outages. Prioritize patch verification where old kernels remain in production. Mitigation focus: Upgrade to a kernel containing the upstream fix or an equivalent vendor backport.; Check Linux distribution, appliance, VMware, and SUSE advisories for fixed package versions.; Restrict untrusted local user access on systems using NFSv4 ACL operations..
