Title
efi/libstub: Free correct pointer on failure
Summary
In the Linux kernel, the following vulnerability has been resolved: efi/libstub: Free correct pointer on failure cmdline_ptr is an out parameter, which is not allocated by the function itself, and likely points into the caller's stack. cmdline refers to the pool allocation that should be freed when cleaning up after a failure, so pass this instead to free_pool().
Severity

An attacker needs local access to the machine to influence the boot environment and cause the kernel image to be loaded.\nAC:H - The `fail_free_cmdline` path is only reachable when `efi_parse_options()`\u0027s `allocate_pool` of a \u2264COMMAND_LINE_SIZE buffer fails, i.e. UEFI boot-services pool exhaustion \u2014 a firmware memory state the attacker cannot reliably influence, since the immediately preceding `efi_convert_cmdline()` allocation of comparable size already succeeded.\nPR:L - Reaching the stub requires a local foothold sufficient to influence the boot (boot entry/command line, chainloaded image, or a reboot on an embedded/kiosk arm64 device); no OS root or CAP_SYS_ADMIN in the running kernel is required.\nUI:N - No victim action is needed \u2014 the attacker with local access triggers the boot themselves, and the faulty path executes automatically inside the stub with no user prompt or interaction.\nS:U - The EFI stub already runs with full UEFI boot-services privilege by design, so corrupting the firmware pool does not cross into a different security authority; this is the standard \"same privilege domain\" case rather than a VM/IOMMU boundary escape.\nC:H - Firmware `FreePool()` on a stack address links stub stack memory into the boot-services free list, so that memory can later be handed to other allocations and read back; allocator-metadata corruption in the pre-boot environment is leverageable as an arbitrary-read primitive.\nI:H - Corrupting the UEFI pool allocator\u0027s free list yields attacker-influenced writes into fully privileged pre-boot memory, which is exploitable for control-flow hijack before any kernel hardening or Secure Boot lockdown is in effect.\nA:H - The invalid free hangs the boot outright on firmware that asserts on a bad pool signature (EDK2 DEBUG deadloop), and otherwise corrupts firmware heap state; the real `cmdline` pool allocation is additionally leaked on every occurrence."

Taxonomy of the tags.




Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Author Source Type Date Other

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
