The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to a boundary condition within the smb2_dump_detail() function in fs/smb/client/smb2ops.c. A local user can trigger an out-of-bounds read error and gain access to sensitive information or crash the kernel.
