Hello, Here are two patches to address a UAF we've been seeing in our stress testing with NFS internally. The first one is to clean up the accesses to the nfs_direct_req fields which is more a matter of correctness than an actual observed problem. The second patch is to address the problem itself. I've been running these patches on my stress test for a few hours now, I would appreciate feedback and review to see if this is the correct way to fix the problem. Thanks, Josef Josef Bacik (2): nfs: properly protect nfs_direct_req fields nfs: fix UAF in direct writes fs/nfs/direct.c | 18 +++++++++++++++--- fs/nfs/write.c | 2 +- include/linux/nfs_fs.h | 1 + 3 files changed, 17 insertions(+), 4 deletions(-) -- 2.43.0
