PT-2024-8403

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.8.0-12873-g2c43c33bfd23 Description The issue is caused by the Linux kernel's BPF allowing access to mptcp-level proto ops from a tcp subflow scope. This can lead to a denial of service. The root cause of the...

CVE-2021-47152

CVE-2021-47152 refers to a Linux kernel fix for data stream corruption in the MPTCP path. The issue arises when mptcp_frag_can_collapse_to() incorrectly assumes only MPTCP uses a page_frag; if other protocols allocate fragments (e.g., plain TCP), memory can be re-used for mptcp_data_frag. The mit...
