Ukuba sengozini (CVE-915-2022) kukhonjwe kumshayeli we-Intel GPU (i4139) okungase kuholele ekonakaleni kwememori noma ukuvuza kwedatha kumemori ye-kernel. Udaba luvela luqala nge-Linux kernel 5.4 futhi luthinta isizukulwane se-12 se-Intel edidiyelwe futhi ecacile ye-GPU, okuhlanganisa i-Tiger Lake, i-Rocket Lake, i-Alder Lake, i-DG1, i-Raptor Lake, i-DG2, i-Arctic Sound, kanye nemindeni ye-Meteor Lake.
Inkinga ibangelwa iphutha elinengqondo elibangela umshayeli wevidiyo ukuthi ashayele ngokungalungile ama-TLB ohlangothini lwe-GPU kwezinye izingxenyekazi zekhompyutha. Kwezinye izimo, ukusethwa kabusha kwe-TLB akuzange kwenzeke nhlobo. Ukushintshashintsha okungalungile kwamabhafa e-TLB kungaholela ekubeni nokwenzeka kwenqubo esebenzisa i-GPU ukufinyelela amakhasi enkumbulo ephathekayo angewona awenqubo enikeziwe, angasetshenziswa ukufunda idatha yangaphandle noma inkumbulo eyonakele kunqubo yangaphandle. Okwamanje akukanqunywa ukuthi ubungozi bungasetshenziswa yini ukukhomba ukonakala kwememori kumakheli afiswayo.
