  3. CVE-2021-47380
In the Linux kernel, the following vulnerability has been resolved: HID: amd_sfh: Fix potential NULL pointer dereference devm_add_action_or_reset() can suddenly invoke amd_mp2_pci_remove() at registration that will cause NULL pointer dereference since corresponding data is not initialized yet. The patch moves initialization of data before devm_add_action_or_reset(). Found by Linux Driver Verification project (linuxtesting.org). [jkosina@suse.cz: rebase]

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: HID: amd_sfh: corrige una posible desreferencia del puntero NULL devm_add_action_or_reset() puede invocar repentinamente amd_mp2_pci_remove() en el registro, lo que provocará una desreferencia del puntero NULL ya que los datos correspondientes aún no se han inicializado. El parche mueve la inicialización de los datos antes de devm_add_action_or_reset(). Encontrado por el proyecto de verificación de controladores de Linux (linuxtesting.org). [jkosina@suse.cz: rebase]
