CVE-2025-68227

CVE-2025-68227 relates to the Linux kernel MPTCP path where sockmap/BPF can override sk_prot, causing improper protocol handling when a non-MPTCP TCP SYN is accepted. The fix makes comparison use sk_family (not sk_prot) to determine the protocol, preventing misclassification of sockets when sockm...

CVE-2023-53811

The CVE-2023-53811 issue affects the Linux kernel’s irdma RDMA driver: the driver could allocate MSIX vectors up to num_online_cpus() + 1, and when this limit is exceeded the kernel would warn while updating CPU affinity with a mask larger than available CPUs. The fix caps MSIX vectors to num_onl...

CVE-2023-53791

CVE-2023-53791 concerns the Linux kernel's md (device-mapper/RAID) code. The issue arises from a mismatch of the holder between export_rdev() and blkdev_put() when mddev->external toggles from 0 to 1: a rdev may be used as a holder by blkdev_get_by_dev() but the corresponding release uses clai...
