Description OSIDB Bzimport 2026-08-15 06:40:08 UTC 
In the Linux kernel, the following vulnerability has been resolved:

rxrpc: Fix leak of released call in recvmsg(MSG_PEEK)

Fix rxrpc_recvmsg() to also drop the ref it holds on an already-released
call if MSG_PEEK is in force (the function holds a ref on the call
irrespective of whether MSG_PEEK is specified or not).
