Also add upper limit checks against the constant MAX_MRU in\ngsm0_receive() and gsm1_receive() to harden against memory corruption of\ngsm->len and gsm->mru.\n\nAll other checks remain as we still need to limit the data according to the\nuser configuration and actual payload size." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
