CVE-2026-98681

In the Linux kernel, the following vulnerability has been resolved:

smb: client: split cifsFileInfo bitfields to avoid shared-byte RMW races

The invalidHandle, swapfile, oplock_break_cancelled, offload,

and status_file_deleted fields are stored in the same bitfield byte

in struct cifsFileInfo, but are updated in different code paths that

may run simultaneously, and are protected by different locks. Since

bitfield assignments generate byte-level read-modify-write operations,

a modification to one flag can overwrite a concurrent modification to

another flag.

To avoid these races, convert these flags from a bitfield to

separate bool fields.
