SUSE CVE-2026-68124

In the Linux kernel, the following vulnerability has been resolved: mctp: serial: handle zero-length frames to prevent rx buffer overflow The MCTP serial receive state machine reads a frame length byte in mctpserialpushheader case 2 and validates it upper-bound-only: if c MCTPSERIALFRAMEMTU...

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-2026-68124

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...
