In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
net: mctp i3c: clean up notifier and buses if driver register fails<\/p>\n
mctp_i3c_mod_init() registers the I3C bus notifier and then walks the
\nexisting buses with i3c_for_each_bus_locked(mctp_i3c_bus_add_new, NULL)
\nbefore registering the I3C device driver. If i3c_driver_register()
\nfails, the function returns the error directly, leaving the notifier
\nregistered and every mctp_i3c_bus object created for the existing buses
\nallocated. The notifier is left pointing into the module that failed to
\nload and the bus list is leaked.<\/p>\n
Mirror the module exit path on this failure: unregister the notifier and
\ntear down the buses that were added before returning the error.<\/p>\n
This issue was identified during our ongoing static-analysis research while
\nreviewing kernel code.<\/p>\n","protected":false},"excerpt":{"rendered":"
