Priority: medium
Bug ID: 74988
Assignee: mesa-dev@lists.freedesktop.org
Summary: Buffer overrun (segfault) decompressing ETC2 texture
in GLBenchmark 3.0 Manhattan
Severity: normal
Classification: Unclassified
OS: Linux (All)
Reporter: court...@lunarg.com
Hardware: x86-64 (AMD64)
Status: NEW
Version: 10.0
Component: Mesa core
Product: Mesa
Saw intermittent segfault running GLBenchmark 3.0's Manhattan test. Narrowed
issue down to writing outside the memory bounds of the texture when
decompressing ETC2 data. Probably the root cause of bug 71002 (which has a nice
repro) as well.
See patch mesa-add-bounds-checking-to-eliminate-buffer-overrun on mesadev for
more details.
