With those fields left unset, garbage function pointers\nmay be stored and later invoked from typec_partner_link_device() when a USB\ndevice is linked to the port. Uninitialized pd_revision and usb_capability\nsimilarly leak stack data through partner sysfs.\n\nZero-initialize the descriptor so optional callbacks remain NULL and the\nremaining fields are zero.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/5414144e202a32437e3eb436cd3f5f00d79ad86e","tags":[]},{"url":"https://git.kernel.org/stable/c/75dc6cb377efd2f4428b7f76d3a590a0bbc10399","tags":[]},{"url":"https://git.kernel.org/stable/c/88c7e458af53ff781a3f1051708395892b325576","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
