In the Linux kernel, the following vulnerability has been resolved: net: ipv4: bound TCP reordering sysctl writes and MTU probe sizes Reject invalid… (CVE-2026-64422)CVE-2026-64422 0 A vulnerability in the Linux kernel's IPv4 TCP stack allowed invalid negative values to be written to the tcp_reordering sysctl parameter, which is stored as an int but used as an unsigned 32-bit value internally. This could cause integer wraparound leading to out-of-bounds reads during MTU probing when tcp_mtu_probing is set to 2. The issue was fixed by validating sysctl inputs to ensure they are at least 1 and hardening the tcp_mtu_probe function against signed integer overflow.
