CVE-2024-35954

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: scsi: sg: Evite la ejecución de desmontaje del dispositivo sg sg_remove_sfp_usercontext() no debe usar sg_device_destroy() después de llamar a scsi_device_put(). sg_device_destroy() está accediendo al scsi_device principal request_queue que ya estará configurado en NULL cuando la llamada anterior a scsi_device_put() eliminó la última referencia al scsi_device principal. La excepción de puntero NULL resultante bloqueará el kernel.

In the Linux kernel, the following vulnerability has been resolved: scsi: sg: Avoid sg device teardown race sg_remove_sfp_usercontext() must not use sg_device_destroy() after calling scsi_device_put(). sg_device_destroy() is accessing the parent scsi_device request_queue which will already be set to NULL when the preceding call to scsi_device_put() removed the last reference to the parent scsi_device. The resulting NULL pointer exception will then crash the kernel.

It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel when modifying certain settings values through debugfs. A privileged local attacker could use this to cause a denial of service. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
