The cifs_find_smb_ses function in fs/cifs/connect.c in the Linux kernel before 2.6.36 does not properly determine the associations between users and sessions, which allows local users to bypass CIFS share authentication by leveraging a mount of a share by a different user.

Security readout for executives and security teams

CVE-2011-1585 is an old Linux kernel CIFS client authorization flaw. On affected systems, one local user could improperly reuse another user's CIFS session and access a share without passing that share's intended authentication check. Exposure is most plausible on legacy Linux systems running kernels before 2.6.36, or vendor kernels without the backported fix, where multiple local users can access systems that mount CIFS/SMB shares. Prioritize remediation for shared Linux servers that mount sensitive SMB shares. For modern supported kernels, business urgency is lower, but unsupported legacy systems should be treated as avoidable access-control risk. Mitigation focus: Upgrade to a vendor-supported kernel containing the CIFS session association fix.; Confirm distro backport status rather than relying only on upstream version numbers.; Restrict local shell access on systems mounting sensitive CIFS shares..
