KERNEL PLUGS RXRPC MEMORY CORRUPTION, RC3 SHIP STEADY

By RepoJournal · Filed · About Linux

Linux 7.1-rc3 landed overnight with a critical rxrpc fix that patches memory safety issues in packet handling when fragments are shared across sockets.

The rxrpc patch [1] closes a gap where DATA and RESPONSE packets with externally-owned paged fragments would bypass security operations entirely—a scenario that splice() and chained skbs can trigger without setting skb_cloned(). This is the kind of subtle memory corruption that sits quietly until it explodes. The RC3 cycle [4] is otherwise steady: clock driver fixes [2] restore boot on SpaceMiT and Mobile EyeQ hardware, and EDAC [3] plugged a device name leak in versalnet. Over in userland, Arch Install enhanced its configuration type system [5] with a new SubConfig abstraction that unifies how all sub-configurations expose their JSON and summary views—cleaner API surface for the install flow.
