Inā ma hope E pili ana iā ZombieLoad Inā hopohopo ʻoe e noʻonoʻo ana pehea e hoʻopau ai i ka hiʻohiʻona Hyper-Threading o Intel e pale ai i ka hoʻohana ʻana i kahi palupalu hou e like me Specter a me Meltdown, a laila e hanu hohonu - ʻaʻole ʻōlelo ʻia ke alakaʻi alakaʻi a Intel e hana i kēia no ka hapa nui. hihia.
Ua like ʻo ZombieLoad me nā hoʻouka ʻaoʻao ʻaoʻao ma mua e koi ana i nā kaʻina hana Intel e hōʻike i ka ʻike koʻikoʻi hiki ke hoʻokaʻawale ʻia a hiki ke loaʻa wale i nā noi e hoʻohana ai. Ua hōʻike mua ʻia nā mea noiʻi palekana aia ka nāwaliwali i ka hapa nui o nā chips Intel a hiki ke hoʻohana ʻia ma Windows, MacOS a me Linux.
ʻAʻole ʻae ʻo Intel, no kāna ʻāpana, i ka nui o ka loiloi o ka pilikia o ZombieLoad. Ua hoʻoholo ka hui e hāʻawi iā ZombieLoad i kahi inoa ʻē aʻe - Microarchitectural Data Sampling (MDS) a i ʻole Microarchitectural Data Sampling. ʻAe, ʻoi aku ka liʻiliʻi o ka weliweli ma mua o kahi kuhikuhi i kekahi mau zombies.
"Hoʻokumu ʻia ka vulnerability MDS ma ka hōʻiliʻili ʻikepili mai nā hale liʻiliʻi i loko o ka CPU me ka hoʻohana ʻana i kahi ʻaoʻao ʻaoʻao hoʻokō speculative hoʻokō kūloko," wehewehe ka hui. "He paʻakikī loa ka hana pono o MDS. ʻAʻole hāʻawi ka nāwaliwali iā ia iho i kahi mea hoʻouka i kahi ala e koho ai i ka ʻikepili a lākou e makemake ai e loaʻa. "
"Ua kamaʻilio mua ʻia ʻo MDS ma ka pae ʻenehana i ka nui o kā mākou 8th a me 9th hanauna Intel Core processors, a me ka XNUMXnd generation Intel Xeon Scalable processor family," wahi a ka hui. "No nā huahana ʻē aʻe i hoʻopilikia ʻia, loaʻa nā hana mitigation ma o ka microcode update i hui pū ʻia me ka ʻōnaehana hana kūpono a me nā polokalamu polokalamu hypervisor, i loaʻa mai kēia lā. Hāʻawi mākou ma kā mākou pūnaewele a hoʻomau i ka paipai ʻana i ka poʻe a pau e hoʻomau i kā lākou ʻōnaehana i kēia lā no ka mea ʻo ia kekahi o nā ala maikaʻi loa e noho palekana ai. "
Ua hōʻike pū ʻo Intel e hana pū ana ka hui noiʻi o ZombieLoad me ka hui a me nā mea ʻē aʻe i ka ʻoihana PC e hoʻopaʻa i ka nāwaliwali ma mua o ka ʻike ʻia ʻana o ka lehulehu. "Makemake mākou e hōʻike i ko mākou mahalo i nā mea noiʻi i hana pū me mākou a me kā mākou mau hoa hana ʻoihana no kā lākou hāʻawi ʻana i kahi hoʻonā i hoʻonohonoho ʻia i kēia pilikia."
No laila pehea e pili ana i ka Hyper-Threading?
Ua ʻōlelo ʻo Intel ʻaʻole pono ka hoʻopau ʻana i ka Hyper-Threading a i ʻole ke koho wale no nā mea hoʻohana PC. ʻOiaʻiʻo, ʻōlelo ʻo Intel aia i kēlā me kēia mea kūʻai aku e hoʻoholo i ka mea e hana ai. Inā ʻaʻole hiki iā ʻoe ke hōʻoiaʻiʻo i ka palekana o ka polokalamu āu i hoʻokomo ai, a laila ʻae, he manaʻo maikaʻi paha ia e hoʻopau i ka Hyper-Threading. Inā hele mai ka polokalamu mai ka hale kūʻai Microsoft, mai kāu keʻena IT, a i hoʻokomo wale ʻia mai ka mea āu i manaʻoʻiʻo ai he kumu hilinaʻi, hiki paha iā ʻoe ke haʻalele iā Hyper-Threading. Pili wale ia i kou hopohopo e pili ana i kou palekana.
"No ka mea, ʻokoʻa ka nui o nā mea i waena o nā mea kūʻai aku, ʻaʻole ʻōlelo ʻo Intel i ka hoʻopau ʻana i ka Hyper-Threading no ka mea he mea nui ia e hoʻomaopopo ʻaʻole ʻo ia wale ke ala e hāʻawi ai i ka pale mai MDS a ʻaʻole hāʻawi i ka pale iā ia iho," wahi a ka hui ma kahi ʻōlelo. .
I ka manawa like, ʻokoʻa nā hopena o nā mea hana ʻōnaehana hana mai kekahi i kekahi.
Ua hoʻokuʻu ʻo Google i kahi hoʻoponopono no Chrome OS e hoʻopau i ka Hyper-Threading no nā Chromebook ma ke ʻano maʻamau. Hiki i ka poʻe makemake e hoʻohuli i ka ʻenehana multi-threading iā lākou iho, manaʻo ka hui.
Ua hoʻokuʻu ʻo Apple i kahi mea hou no MacOS Mojave a hoʻolaha e hiki i nā mea kūʻai aku o ka hui, ʻoi aku ka poʻe ʻike palekana, hiki ke hoʻopau iā Hyper-Threading iā lākou iho.
Ua ʻōlelo ʻo Microsoft ua hoʻokuʻu ʻo ia i nā patch no kāna polokalamu e hōʻemi i ka likelika o MDS, akā ua ʻike pū ʻia e loaʻa hou nā mea kūʻai aku i nā firmware hou mai kā lākou mea hana PC.
Ma muli o ka ʻoiaʻiʻo, no ka hapa nui, ua hoʻoholo nā mea kūʻai aku e haʻalele i ka Hyper-Threading i hiki, ʻaʻole koʻikoʻi ka hoʻoweliweli ZombieLoad e like me ka lā i hala. Eia kekahi, ʻaʻohe hihia i ʻike ʻia o ka nāwaliwali i hoʻohana ʻia i kahi hoʻouka maoli.
I ka manawa like, ʻo ka hoʻohana ʻana i nā patches me ka ʻole o ka hoʻopau ʻana i ka ʻenehana Hyper-Threading aneane ʻaʻole e hōʻemi i ka hana o nā kaʻina hana Intel.
Akā ʻaʻole ʻoe e manaʻoʻiʻo inā ʻoe e nānā Ka hopena o Intel o nā pale palekana i ka hana ke pio ʻo Hyper-Threading. Ua ʻōlelo ka ʻoihana ʻo nā pale palekana, me ka hoʻopau ʻana i ka Hyper-Threading, he hopena liʻiliʻi loa i ka hana.
Ka nū ʻAʻole ʻae nui wau i ka manaʻo o Intel ʻaʻole he pilikia nui ka hoʻopau ʻana i ka Hyper-Threading, ʻoiai ʻo Intel e hōʻike ana i kāna palapala ʻaʻole i loli ka hana. ʻO ka pilikia, ʻo ka hoʻāʻo ʻana o Intel he mea hana i ka wā e hoʻopau ai i ka Hyper-Threading, ʻoiai ʻaʻole i hoʻāʻo ka hui i nā hana hana multi-threaded. Inā ua lawe ʻo Intel i ka Blender, Cinebench, a i ʻole nā hōʻailona ʻē aʻe i hoʻolālā ʻia no nā kaʻina hana multi-core a me multi-threaded, ua ʻike koke mākou i kahi hoʻokō nui.
No ka hōʻike ʻana i ke koʻikoʻi o ka ʻenehana Hyper-Threading, hiki iā ʻoe ke nānā i ka $ 9 Intel i9900-500K a me $ 7 i9700-375K kaʻina hana, ʻo ka ʻokoʻa nui o kā lākou kākoʻo no Hyper-Threading. ʻO ka hoʻopau ʻana i ka Hyper-Threading ma nā kaʻina hana Intel he puʻupuʻu maikaʻi loa ia no ka poʻe e hopohopo nei i ka hana multi-threaded.
Akā aia ka nūhou maikaʻi no ka poʻe e hoʻohana nei i nā kaʻina hana Intel hou loa. Ua ʻōlelo ka ʻoihana he nui o kāna mau mea hana 8th a me 9th hanauna hou i loaʻa i ka hardware microcode fixes, no laila ʻaʻohe kumu no ka poʻe i9-9900K e hoʻopau i ka Hyper-Threading. ʻOi aku ka kiʻekiʻe o ka pilikia o ZombieLoad no nā mea hana kahiko. Pono ka poʻe nona kēia mau ʻōnaehana e hilinaʻi i ka ʻōnaehana hana a me nā polokalamu hou, a me ka hana ʻana o kā lākou antivirus solutions, e hōʻemi i ka pilikia o ka loaʻa ʻana o nā code malicious. E hoʻomanaʻo hou mākou i ka ʻoiaʻiʻo ʻaʻole ʻike ʻia kahi hoʻouka kaua me ZombieLoad.
