A flaw was found in the smb client in the Linux kernel. A potential out-of-bounds error was seen in the smb2_parse_contexts() function. Validate offsets and lengths before dereferencing create contexts in smb2_parse_contexts().
To mitigate this issue, prevent module cifs from being loaded. Please see <https://access.redhat.com/solutions/41278> for how to blacklist a kernel module to prevent it from loading automatically.
