CVE-2023-53106

  2. Vulnerabilities (CVE)
  3. CVE-2023-53106
In the Linux kernel, the following vulnerability has been resolved: nfc: st-nci: Fix use after free bug in ndlc_remove due to race condition This bug influences both st_nci_i2c_remove and st_nci_spi_remove. Take st_nci_i2c_remove as an example. In st_nci_i2c_probe, it called ndlc_probe and bound &ndlc->sm_work with llt_ndlc_sm_work. When it calls ndlc_recv or timeout handler, it will finally call schedule_work to start the work. When we call st_nci_i2c_remove to remove the driver, there may be a sequence as follows: Fix it by finishing the work before cleanup in ndlc_remove CPU0 CPU1 |llt_ndlc_sm_work st_nci_i2c_remove | ndlc_remove | st_nci_remove | nci_free_device| kfree(ndev) | //free ndlc->ndev | |llt_ndlc_rcv_queue |nci_recv_frame |//use ndlc->ndev

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nfc: st-nci: Fix use after free bug en ndlc_remove debido a una condición de ejecución Este error afecta tanto a st_nci_i2c_remove como a st_nci_spi_remove. Tomemos st_nci_i2c_remove como ejemplo. En st_nci_i2c_probe, llamó a ndlc_probe y vinculó &ndlc->sm_work con llt_ndlc_sm_work. Cuando llama a ndlc_recv o al controlador de tiempo de espera, finalmente llamará a schedule_work para iniciar el trabajo. Cuando llamamos a st_nci_i2c_remove para eliminar el controlador, puede haber una secuencia como la siguiente: Arréglelo finalizando el trabajo antes de la limpieza en ndlc_remove CPU0 CPU1 |llt_ndlc_sm_work st_nci_i2c_remove | ndlc_remove | st_nci_remove | nci_free_device| kfree(ndev) | //liberar ndlc->ndev | |llt_ndlc_rcv_queue |nci_recv_frame |//usar ndlc->ndev
