GHSA-w7xc-x24c-mg52

GHSA-w7xc-x24c-mg52 PUBLISHED CVSS 5.5 MEDIUM

Record from GitHub Advisory Database · Published April 1, 2025

In the Linux kernel, the following vulnerability has been resolved: net: mctp: unshare packets when reassembling Ensure that the frag_list used for reassembly isn't shared with other packets. This avoids incorrect reassembly when packets are cloned, and prevents a memory leak due to circular references between fragments and their skb_shared_info. The upcoming MCTP-over-USB driver uses skb_clone which can trigger the problem - other MCTP drivers don't share SKBs. A kunit test is added to reproduce the issue.
