CVE-2025-38544

CVE-2025-38544 : The Linux kernel’s rxrpc implementation had a bug where preallocated call IDs could collide, triggering cleanup assertions when an in-use ID was released. The fix sets the call state in rxrpc_service_prealloc_one() and marks the call as released before cleanup, preventing both as...

CVE-2025-38525

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix irq-disabled in localbhenable The rxrpcassessMTUsize function calls down into the IP layer to find out the MTU size for a route. When accepting an incoming call, this is called from rxrpcnewincomingcall which holds...

CVE-2025-38525

CVE-2025-38525 concerns the Linux kernel RXRPC code path where rxrpc_assess_MTU_size() is invoked with IRQs disabled, triggering a warning in the IP layer via local_bh_enable() and potential interrupt handling issues. The issue is resolved by moving the MTU-size assessment out of rxrpc_init_peer(...

CVE-2025-38524

CVE-2025-38524 concerns the Linux kernel, in net/rxrpc/recvmsg.c, where a race between concurrent recvmsg handlers can occur when a call with a queued event is processed by a thread and later requeued by another thread while holding the user_mutex. This can lead to a second thread operating on a ...
