      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nsmb: client: split cifsFileInfo bitfields to avoid shared-byte RMW races\n\nThe invalidHandle, swapfile, oplock_break_cancelled, offload,\nand status_file_deleted fields are stored in the same bitfield byte\nin struct cifsFileInfo, but are updated in different code paths that\nmay run simultaneously, and are protected by different locks.  Since\nbitfield assignments generate byte-level read-modify-write operations,\na modification to one flag can overwrite a concurrent modification to\nanother flag.\n\nTo avoid these races, convert these flags from a bitfield to\nseparate bool fields.",
