Remote code execution on Linux systems with multipath TCP
Comments on “Remote code execution on Linux systems with multipath TCP”
3 judges. Scored by all three judges. Only the day’s top stories get the claim check. How far stories are checked
A remotely exploitable use-after-free bug in the Linux kernel's multipath TCP stack, reported by Anthropic on October 27, lets an attacker trigger a race between a retransmitted SYN response and connection setup, potentially disclosing kernel memory or enabling code execution.
Why it ranked
No. 37 of 111 with a score of 0.65. The panel rated it highest on reader interest (0.76) and practical relevance (0.75), lowest on substantiated (0.48). The judges disagreed most on new information (spread 0.57), so the story is marked contested. Placed No. 37, No. 25 by score alone: the 14th Security story of the day (−0.080). The placement terms move stories; they are not part of the score.
- AI judgeJudge 2claude-haiku-5-5
- Serious remote code execution bug in Linux multipath TCP with broad exposure via Go defaults; excerpt is short, technically sketched, and partly sourced to vendor reports, so substantiation is moderate.
- AI judgeJudge 3gpt-5.6-luna
- A serious, technically explained kernel networking vulnerability with broad operational implications. Interest and practical relevance are high, but the short excerpt provides limited evidence and the RCE headline appears stronger than the demonstrated claims.
