CVE-2024-50268

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-50268
In the Linux kernel, the following vulnerability has been resolved: usb: typec: fix potential out of bounds in ucsi_ccg_update_set_new_cam_cmd() The "*cmd" variable can be controlled by the user via debugfs. That means "new_cam" can be as high as 255 while the size of the uc->updated[] array is UCSI_MAX_ALTMODES (30). The call tree is: ucsi_cmd() // val comes from simple_attr_write_xsigned() -> ucsi_send_command() -> ucsi_send_command_common() -> ucsi_run_command() // calls ucsi->ops->sync_control() -> ucsi_ccg_sync_control()

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: typec: se corrige un posible error fuera de los límites en ucsi_ccg_update_set_new_cam_cmd() La variable "*cmd" puede ser controlada por el usuario a través de debugfs. Esto significa que "new_cam" puede tener un valor de hasta 255, mientras que el tamaño de la matriz uc->updated[] es UCSI_MAX_ALTMODES (30). El árbol de llamadas es: ucsi_cmd() // val proviene de simple_attr_write_xsigned() -> ucsi_send_command() -> ucsi_send_command_common() -> ucsi_run_command() // llama a ucsi->ops->sync_control() -> ucsi_ccg_sync_control()
