Title

Уязвимость операционной системы Linux, позволяющая нарушителю считывать или записывать в ячейки памяти ядра

Summary

Уязвимость mm подсистемы ядра операционной системы Linux связана с недостатками контроля доступа. Эксплуатация уязвимости может позволить нарушителю, действующему локально, из-за того, что неправильно реализуется механизм защиты CONFIG_STRICT_DEVMEM, считывать или записывать в ячейки памяти ядра в первом мегабайте (и обходить ограничения доступа к slab-распределению) при помощи приложения, которое открывает файл /dev/mem, связанный с arch/x86/mm/init.c и drivers/char/mem.c.

Severity

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.
