CVE-2025-38315

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2025-38315
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintel: Check dsbr size from EFI variable Since the size of struct btintel_dsbr is already known, we can just start there instead of querying the EFI variable size. If the final result doesn't match what we expect also fail. This fixes a stack buffer overflow when the EFI variable is larger than struct btintel_dsbr.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: Bluetooth: btintel: Verificar el tamaño de dsbr desde la variable EFI. Dado que el tamaño de struct btintel_dsbr ya se conoce, podemos empezar por ahí en lugar de consultar el tamaño de la variable EFI. Si el resultado final no coincide con lo esperado, también falla. Esto corrige un desbordamiento del búfer de pila cuando la variable EFI es mayor que struct btintel_dsbr.
