CVE-2026-23060

  2. Vulnerabilities (CVE)
  3. CVE-2026-23060
In the Linux kernel, the following vulnerability has been resolved: crypto: authencesn - reject too-short AAD (assoclen<8) to match ESP/ESN spec authencesn assumes an ESP/ESN-formatted AAD. When assoclen is shorter than the minimum expected length, crypto_authenc_esn_decrypt() can advance past the end of the destination scatterlist and trigger a NULL pointer dereference in scatterwalk_map_and_copy(), leading to a kernel panic (DoS). Add a minimum AAD length check to fail fast on invalid inputs.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: crypto: authencesn - rechazar AAD demasiado corto (assoclen&lt;8) para coincidir con la especificación ESP/ESN authencesn asume un AAD con formato ESP/ESN. Cuando assoclen es más corto que la longitud mínima esperada, crypto_authenc_esn_decrypt() puede avanzar más allá del final de la scatterlist de destino y activar una desreferencia de puntero NULL en scatterwalk_map_and_copy(), lo que lleva a un pánico del kernel (DoS). Añadir una comprobación de longitud mínima de AAD para fallar rápidamente con entradas no válidas.
