  3. CVE-2023-52693
In the Linux kernel, the following vulnerability has been resolved: ACPI: video: check for error while searching for backlight device parent If acpi_get_parent() called in acpi_video_dev_register_backlight() fails, for example, because acpi_ut_acquire_mutex() fails inside acpi_get_parent), this can lead to incorrect (uninitialized) acpi_parent handle being passed to acpi_get_pci_dev() for detecting the parent pci device. Check acpi_get_parent() result and set parent device only in case of success. Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ACPI: vídeo: comprueba si hay errores al buscar el dispositivo de retroiluminación principal. Si la llamada acpi_get_parent() en acpi_video_dev_register_backlight() fallo, por ejemplo, porque acpi_ut_acquire_mutex() fallo dentro de acpi_get_parent), esto puede provocar que se pase el identificador acpi_parent incorrecto (no inicializado) a acpi_get_pci_dev() para detectar el dispositivo pci principal. Verifique el resultado de acpi_get_parent() y configure el dispositivo principal solo en caso de éxito. Encontrado por el Centro de verificación de Linux (linuxtesting.org) con SVACE.
