Ubungozi kumshayeli wevidiyo we-Intel i915

Kumshayeli wehluzo we-Intel i915 ikhonjiwe ubuthakathaka obubili. Okokuqala ukuba sengozini (I-CVE-2019-0155) ithinta amasistimu ane-Intel Gen9 GPU (i-Skylake) futhi ikuvumela ukuthi uguqule okufakiwe kuthebula lekhasi lememori usuke esikhaleni somsebenzisi ngokukhohlisa nge-MMIO (Okukhipha I-Memory Mapped Input). Inkinga ivumela umhlaseli ukuthi athole ukufinyelela kulwazi olugcinwe kumemori ye-kernel futhi akhulise amalungelo akhe ohlelweni.

Owesibili inkinga (I-CVE-2019-0154) ivela ezinhlelweni ezine-Intel Gen8 kanye ne-Gen9 GPUs (i-Broadwell ne-Skylake), futhi ingasetshenziswa ukuqalisa ukwenqatshwa kwesevisi (i-system hang) ngokufinyelela amarejista athile e-GPU nge-MMIO, okuholela ekutheni i-GPU ibekwe esimweni esingalungile.

Izinkinga kuqedwe ku-Linux kernel ibuyekeza 5.4-rc7, 5.3.11, 4.19.84, 4.14.154, 4.9.201, 4.4.201. Izibuyekezo zephakheji sezikhishiwe ekusabalaliseni okuningi: Debian, Ubuntu, RHEL, I-Arch Linux, vulaSUSE / SUSE, Fedora.
