Kusintha kwatsopano kwa kernel ya Ubuntu, koma nthawi ino kukonza zolakwika zitatu za Intel

Kupitilira sabata yapitayo tidasindikiza nkhani momwe tidafotokozera kuti Canonical yasintha kernel ya Ubuntu kuti iwononge zolakwika zambiri zachitetezo. Panali nsikidzi zambiri kuposa momwe zimakhalira muzosintha zamtunduwu, zimakhala zachilendo kuphimba za 4-5. Maola angapo apitawo, kampaniyo yakhazikitsa ina Kusintha kwa kernel ya Ubuntu, koma nthawi ino, ngakhale kuti nthawi zonse amalangizidwa kuvomereza kusintha, sikofunikira kwambiri.

M'malo mwake, mwa malipoti awiriwa, ogwiritsa ntchito ambiri amangokhudzidwa ndi imodzi. Choyamba ndi Kutumiza & Malipiro, ndipo imakonza zolakwika 5 zomwe zimakhudza Ubuntu 14.04. Timakumbukira kuti mtundu uwu wa Ubuntu, womwe uli ndi zaka 8 za moyo, uli mu gawo la ESM, ndiko kuti, kugwiritsa ntchito mwayi wowonjezera momwe zolakwika zachitetezo za kernel zikupitilirabe. Lipoti lina ndi Kutumiza & Malipiro, ndipo iyi iyenera kukopa chidwi cha ogwiritsa ntchito ambiri a Ubuntu, chifukwa imakhudza mitundu yonse yothandizidwa, kuphatikizapo 16.04 ndi 14.04, yomwe, monga tafotokozera, ili mu gawo la ESM.

Ubuntu chimakwirira nsikidzi zitatu zomwe zimakhudza mitundu yake yonse

Nsikidzi zitatu zomwe zafotokozedwa mu lipoti laposachedwa ndi mafotokozedwe awo ndi:

• CVE-2022-21123- Zinadziwika kuti ma processor ena a Intel sanachite zonse zoyeretsa pama buffers ogawana nawo ambiri. Wachiwembu wakomweko atha kugwiritsa ntchito izi kuti awulule zambiri zachinsinsi.
• CVE-2022-21125- Zinadziwika kuti ma processor ena a Intel sanachite zonse zoyeretsera pazambiri za microarchitecture. Wachiwembu wakomweko atha kugwiritsa ntchito izi kuti awulule zidziwitso zachinsinsi.
• CVE-2022-21166- Zinadziwika kuti ma processor ena a Intel sanali kuyeretsa bwino panthawi yolemba zolemba zapadera. Wachiwembu wakomweko atha kugwiritsa ntchito izi kuti awulule zambiri zachinsinsi.

Kuti mudziteteze ku ziwopsezo zonsezi, ingoyambitsani pulogalamu iliyonse yogawa ndikuyika ma kernel phukusi. Atha kukhazikitsidwanso potsegula terminal ndikulemba zodziwika bwino «sudo apt update && kukweza kukweza«. Ngakhale muzochitika zonse zitatu "wowukira wamba" amatchulidwa, ndi bwino kutetezedwa, ndipo kukonzanso kumawononga ndalama zochepa.
