Description

An information leak flaw was found due to uninitialized memory in the Linux kernel's TIPC protocol subsystem, in the way a user sends a TIPC datagram to one or more destinations. This flaw allows a local user to read some kernel memory. This issue is limited to no more than 7 bytes, and the user cannot control what is read. This flaw affects the Linux kernel versions prior to 5.17-rc1.
