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 (Skylake) GPUs futhi ivumela ukuhlaselwa kwesikhala somsebenzisi ukuze kulungiswe okufakiwe kwethebula lememori ngokusebenzisa i-MMIO (Memory Mapped Input Output). Inkinga ivumela umhlaseli ukuthi afinyelele ulwazi olugcinwe kumemori ye-kernel futhi akhulise amalungelo abo.

Owesibili inkinga (I-CVE-2019-0154) kwenzeka kumasistimu ane-Intel Gen8 kanye ne-Gen9 (i-Broadwell ne-Skylake) GPUs futhi ingasetshenziswa ukudala ukunqatshelwa kwesevisi (ukumiswa kwesistimu) ngokufinyelela amarejista athile e-GPU nge-MMIO, okubangela i-GPU ukuthi ingene esimweni esingavumelekile.

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 ekusatshalalisweni okuningi: Debian, Ubuntu, RHEL, I-Arch Linux, vulaSUSE / SUSE, Fedora.
