Description Thomas Leroy 2022-01-19 14:47:38 UTC

NVIDIA Linux kernel distributions contain a vulnerability in nvmap
NVGPU_IOCTL_CHANNEL_SET_ERROR_NOTIFIER, where improper access control may lead
to code execution, compromised integrity, or denial of service.

Comment 1 Thomas Leroy 2022-01-19 14:50:05 UTC
I can't find signs of "NVGPU_IOCTL_CHANNEL_SET_ERROR_NOTIFIER" in our sources, so again, probably NVIDIA stuff
Comment 2 Takashi Iwai 2022-01-19 16:23:03 UTC
Agreed, it must be Nvidia downstream stuff.
Comment 3 Thomas Leroy 2022-01-19 17:29:56 UTC
Thanks Takashi, closing.
