{"id":"CVE-2024-50078","summary":"Bluetooth: Call iso_exit() on module unload","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: Call iso_exit() on module unload\n\nIf iso_init() has been called, iso_exit() must be called on module\nunload. Without that, the struct proto that iso_init() registered with\nproto_register() becomes invalid, which could cause unpredictable\nproblems later. In my case, with CONFIG_LIST_HARDENED and\nCONFIG_BUG_ON_DATA_CORRUPTION enabled, loading the module again usually\ntriggers this BUG():\n\n  list_add corruption. next-\u003eprev should be prev (ffffffffb5355fd0),\n    but was 0000000000000068.
