Severity

7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: pinctrl: core: delete incorrect free in pinctrl_enable() The "pctldev" struct is allocated in devm_pinctrl_register_and_init(). It's a devm_ managed pointer that is freed by devm_pinctrl_dev_release(), so freeing it in pinctrl_enable() will lead to a double free. The devm_pinctrl_dev_release() function frees the pindescs and destroys the mutex as well.

There is no remote or adjacent protocol handler involved.\nAC:L - The failing condition in `pinctrl_claim_hogs()` includes `-ENOMEM` from `create_pinctrl()`\u0027s `kzalloc()` and from `pinctrl_dt_to_map()`, which a local attacker can drive via sustained memory pressure timed against a driver probe. Once the free happens the devres release is guaranteed to run on the dangling pointer, so no unwinnable race is required.\nPR:L - An unprivileged local account suffices to apply the allocation pressure that induces the `pinctrl_claim_hogs()` error path on a system where an affected pinctrl driver probes or re-probes. No capability check guards `pinctrl_enable()` itself, and the resulting double free is in shared kernel slab state.\nUI:N - The vulnerable path executes autonomously during driver probe and devres teardown; no victim action such as mounting a filesystem or opening a file is needed.\nS:U - The corruption is confined to kernel slab memory within the same security authority \u2014 a standard kernel-level compromise with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - `pinctrl_unregister()` reads extensively through the freed `pctldev` (`-\u003emutex`, `-\u003enode`, `-\u003edesc-\u003epins`, `-\u003ep`), and if the slab object is reclaimed by attacker-groomed data the double free enables heap-layout manipulation that can be leveraged into arbitrary kernel memory disclosure.\nI:H - The stale `list_del(\u0026pctldev-\u003enode)` writes through `next`/`prev` pointers in freed \u2014 and potentially attacker-controlled \u2014 memory, giving a write-what-where primitive, while the second `kfree()` corrupts the slab freelist and permits overlapping-allocation attacks leading to control-flow hijack.\nA:H - Double free plus use-after-free reliably corrupts the SLUB freelist and locks/destroys an already-destroyed mutex, producing an oops or panic; drivers that ignore `pinctrl_enable()`\u0027s return value (e.g. sppctl) leave a dangling pointer live until unbind, guaranteeing a later crash."

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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
