A compound userspace bug. First it attempts to mmap a purged buffer (i.e. one it has told the kernel to discard under memory pressure) and then doesn't check the error return and attempts to dereference an invalid pointer. The bug is most likely an old one in mesa (given chrome likes to statically link crap into its binary). |
