Description
In the Linux kernel, the following vulnerability has been resolved:
rxrpc: only handle RESPONSE during service challenge
Only process RESPONSE packets while the service connection is still in
RXRPC_CONN_SERVICE_CHALLENGING. Check that state under state_lock before
running response verification and security initialization, then use a local
secured flag to decide whether to queue the secured-connection work after
the state transition. This keeps duplicate or late RESPONSE packets from
re-running the setup path and removes the unlocked post-transition state
test.
Affected configurations
• linux linux kernel (>= 2.6.22 < 6.6.136)
• linux linux kernel (>= 6.7 < 6.12.84)
• linux linux kernel (>= 6.13 < 6.18.23)
• linux linux kernel (>= 6.19 < 6.19.13)
