CVE-2026-43381

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> nouveau/dpcd: return EBUSY for aux xfer if the device is asleep<br /> <br /> If we have runtime suspended, and userspace wants to use /dev/drm_dp_*<br /> then just tell it the device is busy instead of crashing in the GSP<br /> code.<br /> <br /> WARNING: CPU: 2 PID: 565741 at drivers/gpu/drm/nouveau/nvkm/subdev/gsp/rm/r535/rpc.c:164 r535_gsp_msgq_wait+0x9a/0xb0 [nouveau]<br /> CPU: 2 UID: 0 PID: 565741 Comm: fwupd Not tainted 6.18.10-200.fc43.x86_64 #1 PREEMPT(lazy)<br /> Hardware name: LENOVO 20QTS0PQ00/20QTS0PQ00, BIOS N2OET65W (1.52 ) 08/05/2024<br /> RIP: 0010:r535_gsp_msgq_wait+0x9a/0xb0 [nouveau]<br /> <br /> This is a simple fix to get backported. We should probably engineer a<br /> proper power domain solution to wake up devices and keep them awake<br /> while fw updates are happening.
