"value": "OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, OBI\u0027s replacement ELF parser trusts section offsets, counts, and string offsets from the executable file. A crafted local ELF can make OBI dereference invalid section pointers or slice past string tables, causing the agent to panic while determining the process language. This issue has been patched in version 0.9.0."

"value": "OpenTelemetry eBPF Instrumentation proporciona instrumentaci\u00f3n eBPF basada en el est\u00e1ndar OpenTelemetry. Antes de la versi\u00f3n 0.9.0, el analizador ELF de reemplazo de OBI conf\u00eda en los desplazamientos de secci\u00f3n, los recuentos y los desplazamientos de cadena del archivo ejecutable. Un ELF local manipulado puede hacer que OBI desreferencie punteros de secci\u00f3n no v\u00e1lidos o acceda m\u00e1s all\u00e1 de las tablas de cadenas, lo que provoca que el agente entre en p\u00e1nico mientras determina el lenguaje del proceso. Este problema ha sido parcheado en la versi\u00f3n 0.9.0."

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.
