Summary
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Remove skb secpath if xfrm state is not found Hardware returns a unique identifier for a decrypted packet's xfrm state, this state is looked up in an xarray. However, the state might have been freed by the time of this lookup. Currently, if the state is not found, only a counter is incremented. The secpath (sp) extension on the skb is not removed, resulting in sp->len becoming 0. Subsequently, functions like __xfrm_policy_check() attempt to access fields such as xfrm_input_state(skb)->xso.type (which dereferences sp->xvec[sp->len - 1]) without first validating sp->len. This leads to a crash when dereferencing an invalid state pointer. This patch prevents the crash by explicitly removing the secpath extension from the skb if the xfrm state is not found after hardware decryption. This ensures downstream functions do not operate on a zero-length secpath.

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net/mlx5e: Eliminar secpath de skb si no se encuentra el estado xfrm El hardware devuelve un identificador \u00fanico para el estado xfrm de un paquete descifrado, este estado se busca en un xarray. Sin embargo, el estado podr\u00eda haberse liberado en el momento de esta b\u00fasqueda. Actualmente, si no se encuentra el estado, solo se incrementa un contador. La extensi\u00f3n secpath (sp) en skb no se elimina, lo que hace que sp-\u0026gt;len se convierta en 0. Posteriormente, funciones como __xfrm_policy_check() intentan acceder a campos como xfrm_input_state(skb)-\u0026gt;xso.type (que desreferencia sp-\u0026gt;xvec[sp-\u0026gt;len - 1]) sin validar primero sp-\u0026gt;len. Esto provoca un fallo al desreferenciar un puntero de estado no v\u00e1lido. Este parche evita el fallo eliminando expl\u00edcitamente la extensi\u00f3n secpath de skb si no se encuentra el estado xfrm despu\u00e9s del descifrado del hardware. Esto garantiza que las funciones posteriores no operen en un secpath de longitud cero.

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.

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.
