Aug 4 RESCORED — CVE-2024-50090 (Linux). CVSS 7.8 → 5.5 (NVD).
Description
In the Linux kernel, the following vulnerability has been resolved:
drm/xe/oa: Fix overflow in oa batch buffer
By default xe_bb_create_job() appends a MI_BATCH_BUFFER_END to batch
buffer, this is not a problem if batch buffer is only used once but
oa reuses the batch buffer for the same metric and at each call
it appends a MI_BATCH_BUFFER_END, printing the warning below and then
overflowing.
[ 381.072016] ------------[ cut here ]------------
[ 381.072019] xe 0000:00:02.0: [drm] Assertion `bb->len * 4 + bb_prefetch(q->gt) <= size` failed!
platform: LUNARLAKE subplatform: 1
graphics: Xe2_LPG / Xe2_HPG 20.04 step B0
media: Xe2_LPM / Xe2_HPM 20.00 step B0
tile: 0 VRAM 0 B
GT: 0 type 1
So here checking if batch buffer already have MI_BATCH_BUFFER_END if
not append it.
v2:
- simply fix, suggestion from Ashutosh
(cherry picked from commit 9ba0e0f30ca42a98af3689460063edfb6315718a)
