The rs_ioctl function in drivers/char/amiserial.c in the Linux kernel 2.6.36.1 and earlier does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via a TIOCGICOUNT ioctl call.

Security readout for executives and security teams

CVE-2010-4076 is an old Linux kernel information disclosure. A local user could ask the Amiga serial driver for counters and receive leftover kernel stack data. This is not a remote break-in by itself, but it may expose sensitive memory that helps other attacks on unpatched legacy systems. Exposure is most plausible on legacy Linux systems running kernel 2.6.36.1 or earlier, or vendor kernels lacking the backported fix, where the amiserial driver is present and accessible to local users. Prioritize this for legacy Linux environments, especially shared-user or shell-access systems. For modern, supported kernels, urgency is usually low after confirming vendor patch status. The main business risk is outdated infrastructure retaining known local kernel disclosure flaws. Mitigation focus: Update affected Linux kernels using vendor-supported packages.; Confirm the amiserial stack-disclosure patch is present or backported.; Review distribution advisories for affected legacy kernel builds..
