Kanopfuura svondo rapfuura takaburitsa chinyorwa umo isu takashuma kuti Canonical yakagadziridza Ubuntu kernel kuvhara zvikanganiso zvakawanda zvekuchengetedza. Paive netsikidzi dzakawanda kupfuura zvakajairwa mumhando iyi yekuvandudza, zvave zvakajairika kuvhara nezve 4-5. Maawa mashoma apfuura, kambani yakatanga imwe Ubuntu kernel kugadzirisa, asi panguva ino, kunyange zvazvo zvichigara zvichikurudzirwa kubvuma kuchinja, hazvisi zvekukurumidzira.
Muchokwadi, pamishumo miviri, vashandisi vazhinji vanongofunga nezve imwe chete. Yokutanga ndiyo USN-5484-1, uye inogadzirisa 5 bugs inobata Ubuntu 14.04. Isu tinorangarira kuti iyi vhezheni yeUbuntu, ine makore masere ehupenyu, iri muchikamu cheESM, ndiko kuti, kutora mukana werutsigiro rwakawedzerwa umo kukanganisa kwekernel kunoramba kuchifukidzwa. Imwe rondedzero ndeye USN-5485-1, uye iyi inofanirwa kukwevera kutarisisa kwevazhinji vashandisi veUbuntu, sezvo ichibata ese anotsigirwa shanduro, kusanganisira 16.04 uye 14.04, iyo, sezvatataura, iri muchikamu cheESM.
Ubuntu inovhara mabhugi matatu anobata mavhezheni ayo ese
Iwo matatu mabhugi akafukidzwa mumushumo wazvino uno uye tsananguro dzadzo ndeidzi:
- CVE-2022-21123- Mamwe maIntel processors akawanikwa asina kuita zvizere zviito zvekuchenesa pane akawanda-musimboti akagovaniswa buffers. Anorwisa munharaunda anogona kushandisa izvi kuratidza ruzivo rwakadzama.
- CVE-2022-21125-Zvakaonekwa kuti mamwe maIntel processors haana kuita zvizere zviito zvekuchenesa pane microarchitecture kuzadza buffers. Murwi wepano anogona kurwisa anogona kushandisa izvi kuratidza ruzivo rwakadzama.
- CVE-2022-21166-Zvakaonekwa kuti mamwe maIntel processors akange asiri kunyatsoita kuchenesa panguva chaiyo yekunyora mashandiro kune akakosha marejista. Anorwisa munharaunda anogona kushandisa izvi kuratidza ruzivo rwakadzama.
Kuti uzvidzivirire kubva kune zvese izvi kutyisidzira, ingo tanga yega yega yekugovera software uye isa iwo matsva kernel mapakeji. Ivo vanogona zvakare kuiswa nekuvhura terminal uye nekunyora iyo yakakurumbira «sudo apt kugadzirisa && sudo apt kusimudzira«. Kunyangwe muzviitiko zvese zvitatu "anorwisa wenzvimbo" anotaurwa, zviri nani kuchengetedzwa, uye kugadzirisa kunodhura zvishoma.
