For example TZMEM parts ('__scm->mempool')\nare initialized later in the probe, but users of it (__scm_smc_call())\nrely on the '__scm' variable.\n\nThis fixes theoretical NULL pointer exception, triggered via introducing\nprobe deferral in SCM driver with call trace:\n\n qcom_tzmem_alloc+0x70/0x1ac (P)\n qcom_tzmem_alloc+0x64/0x1ac (L)\n qcom_scm_assign_mem+0x78/0x194\n qcom_rmtfs_mem_probe+0x2d4/0x38c\n platform_probe+0x68/0xc8"

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: firmware: qcom: scm: Limpieza de la variable global '__scm' en caso de fallos en la sonda Si el controlador SCM hace que la sonda falle, no deber\u00eda dejar asignada la variable global '__scm', porque los usuarios externos de este controlador asumir\u00e1n que la sonda finaliz\u00f3 correctamente. Por ejemplo, las partes TZMEM ('__scm->mempool') se inicializan m\u00e1s tarde en la sonda, pero los usuarios de esta (__scm_smc_call()) dependen de la variable '__scm'.
