  3. CVE-2025-21785
In the Linux kernel, the following vulnerability has been resolved: arm64: cacheinfo: Avoid out-of-bounds write to cacheinfo array The loop that detects/populates cache information already has a bounds check on the array size but does not account for cache levels with separate data/instructions cache. Fix this by incrementing the index for any populated leaf (instead of any populated level).

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: arm64: cacheinfo: evitar escritura fuera de los límites en la matriz cacheinfo El bucle que detecta/completa la información de caché ya tiene una comprobación de los límites en el tamaño de la matriz, pero no tiene en cuenta los niveles de caché con caché de datos/instrucciones independiente. Solucione esto incrementando el índice de cualquier hoja completada (en lugar de cualquier nivel completo).
