I-Linux kernel ithuthukiswa yiLinux Torvalds, kepha ibuye inakekele ukuyigcina iyingxenye yeqembu labo. Akunjalo ekusatshalalisweni okufana no-Ubuntu, ngoba yi-Canonical ephethe ukugcina umnyombo wohlelo lwakho lokusebenza, ikhipha izibuyekezo zokuphepha nezokulungisa ngezikhathi ezithile, isikhathi sokugcina ngomhlaka 17 kule nyanga. Baphinde bakwenza futhi emahoreni ambalwa edlule, bethula izinhlobo ezintsha ze-kernel zezinguqulo ezimbili zokugcina ze-Ubuntu.
Mhlawumbe, uma bekungenjalo ukuba sengcupheni okuphezulu Ngabe angibhalanga le ndatshana ngibika ngokwehluleka. Kepha isinambuzane esiqoqwa ngumbiko I-USN-4313-1, yinye kuphela, yebo ibhalwe ngale ndlela, ngakho ekugcineni nginqume ukuyabelana nani nonke. Ukuba sengozini yi I-CVE-2020-8835 futhi, ekuqaleni, kuthinta Ubuntu 19.10 Eoan Ermine no-Ubuntu 18.04 LTS Bionic Beaver. Siyakhumbula lapha ukuthi Ubuntu 19.04 Disco Dingo ayisakujabuleli ukwesekwa.
Kubuyekezwe i-kernel ukulungisa i-bug ku-Eoan Ermine naseBionic Beaver
Igama noma incazelo yobungozi ibalula "Ukuqinisekiswa Kokufaka Okungalungile kwe-eBPF [ZDI-CAN-10780]", futhi emininingwaneni ichaza ukuthi:
UManfred Paul uthole ukuthi isihloli se-bpf ku-Linux kernel asibalanga log imikhawulo yokusebenza okuthile ngendlela efanele. Un umhlaseli wendawo angasebenzisa lokhu ukudalula imininingwane ebucayi (inkumbulo ye-kernel) noma uthole amalungelo okuphatha.
Ubukhulu obabelwe buxhomeke kukho konke ukusetshenziswa kalula kwesiphazamisi nomonakalo ongawudala. Izindaba ezimnandi ukuthi ukuze usebenzise ubungozi, udinga ukufinyelela ngokomzimba kwikhompyutha, okusho ngamanye amagama ukuthi akekho umuntu ongenza noma yini ukude. Ngokwengeziwe nangokujwayelekile, iCanonical ishicilele imininingwane ngemuva kokushicilela amaphakheji amasha asevele asilindele njengesibuyekezo. Ukuze ushintsho lusebenze futhi sivikeleke ngokuphelele, kuzodingeka ukuqala kabusha ikhompyutha.
