The previously registered net_devices are then freed by\nmtk_free_dev() while still in NETREG_REGISTERED state, hitting the\nBUG_ON(dev->reg_state != NETREG_UNREGISTERED).\n\nRoute the register_netdev() failure to err_unreg_netdev so the net_devices\nregistered so far are properly unregistered before being freed.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/0fdb944d4df02223c67d5e65c4c134ecb57a5668","tags":[]},{"url":"https://git.kernel.org/stable/c/245bea0c7ab278150c70366bdeb69b901327133c","tags":[]},{"url":"https://git.kernel.org/stable/c/310d1ac61a4d5a2ca8356a3a48d263acf54503ce","tags":[]},{"url":"https://git.kernel.org/stable/c/7254b702e556158e34b4d7c168b5d8e7da5978af","tags":[]},{"url":"https://git.kernel.org/stable/c/ab3bde3b3e56331b4f53a1f6cf4e5e9d1c14c1a0","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
