Description

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix oops due to non-existence of prealloc backlog struct If an AF_RXRPC service socket is opened and bound, but calls are preallocated, then rxrpc_alloc_incoming_call() will oops because the rxrpc_backlog struct doesn't get allocated until the first preallocation is made. Fix this by returning NULL from rxrpc_alloc_incoming_call() if there is no backlog struct. This will cause the incoming call to be aborted.

Affected configurations

• linux linux kernel (>= 4.9 < 5.4.296) • linux linux kernel (>= 5.5 < 5.10.240) • linux linux kernel (>= 5.11 < 5.15.189) • linux linux kernel (>= 5.16 < 6.1.146) • linux linux kernel (>= 6.2 < 6.6.99) • linux linux kernel (>= 6.7 < 6.12.39) • linux linux kernel (>= 6.13 < 6.15.7) • linux linux kernel 6.16 • debian debian linux 11.0
