CVE-2023-53836

Summary of CVE-2023-53836 (Linux kernel): A race exists in the sockmap path (bpf/sockmap) where skb objects in the sk_psock_backlog can be referenced after userspace drains the skb, leading to a use-after-free when skb_dequeue() occurs after the skb has been freed. The published fixes add skb_get...

CVE-2023-53825

CVE-2023-53825 affects the Linux kernel’s kcm_sendmsg() for SOCK_DGRAM. A memory-leak in the error path could corrupt the MSG_MORE queue when a partial copy occurs; the fix updates kcm_tx_msg(head)->last_skb and adds purge behavior on failure (like UDP via udp_flush_pending_frames) to avoid qu...

CVE-2022-50666

CVE-2022-50666 relates to the Linux kernel’s RDMA/siw subsystem. The issue arises in QP destruction: the destroy path did not wait for all siw references to the QP to be dropped, allowing a use-after-free when delayed siw_cm_work_handler references a QP already freed after the destroy call. Repor...
