CVE-2026-43455

In the Linux kernel, the following vulnerability has been resolved: mctp: route: hold key-lock in mctpflowprepareoutput mctpflowprepareoutput checks key-dev and may call mctpdevsetkey, but it does not hold key-lock while doing so. mctpdevsetkey and mctpdevreleasekey are annotated with...

CVE-2026-43455

In CVE-2026-43455, multiple sources confirm a race in the Linux kernel MCTP module: mctp_flow_prepare_output() checks key->dev and may call mctp_dev_set_key() without holding key->lock, while both mctp_dev_set_key() and mctp_dev_release_key() require the lock. This can allow concurrent path...
