EFI SLAB use after free in generic/388 run

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Just saw this during a xfstests auto run on virtio with default
XFS parameters.  I don't think I saw this before when running the
same config, so it might not be 100% reproducible.  I'd be surpised
if my laptop has bad ram, but who knows..
