"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ipv6: unexport __init-annotated seg6_hmac_init()\n\nEXPORT_SYMBOL and __init is a bad combination because the .init.text\nsection is freed up after the initialization. Hence, modules cannot\nuse symbols annotated __init. The access to a freed symbol may end up\nwith kernel panic.\n\nmodpost used to detect it, but it has been broken for a decade.\n\nRecently, I fixed modpost so it started to warn it again, then this\nshowed up in linux-next builds.\n\nThere are two ways to fix it:\n\n - Remove __init\n - Remove EXPORT_SYMBOL\n\nI chose the latter for this case because the caller (net/ipv6/seg6.c)\nand the callee (net/ipv6/seg6_hmac.c) belong to the same module.\nIt seems an internal function call in ipv6.ko."
