CVE-2026-68124

A flaw was found in the Linux kernel's Message Control Transport Protocol MCTP serial driver. The driver's receive state machine incorrectly handles zero-length frames, leading to an out-of-bounds write. A local attacker with CAPNETADMIN capabilities can exploit this vulnerability by sending...

CVE-2026-68314

A flaw was found in the Linux kernel's MCTP I3C network module. When the i3cdriverregister function fails during module initialization, the system does not properly unregister notifiers and deallocate bus objects. This oversight leads to a memory leak, which could be exploited by a local attacker...

CVE-2026-68124

CVE-2026-68124 affects the Linux kernel MCTP serial driver. A zero-length frame could cause an out-of-bounds write in the receive path when rxlen == 0, requiring CAP_NET_ADMIN to attach the MCTP line discipline and bring up the netdev. The fix routes zero-length frames to STATE_TRAILER (instead o...
