CVE-2024-53094

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> RDMA/siw: Add sendpage_ok() check to disable MSG_SPLICE_PAGES<br /> <br /> While running ISER over SIW, the initiator machine encounters a warning<br /> from skb_splice_from_iter() indicating that a slab page is being used in<br /> send_page. To address this, it is better to add a sendpage_ok() check<br /> within the driver itself, and if it returns 0, then MSG_SPLICE_PAGES flag<br /> should be disabled before entering the network stack.<br /> <br /> A similar issue has been discussed for NVMe in this thread:<br /> https://lore.kernel.org/all/20240530142417.146696-1-ofir.gal@volumez.com/<br /> <br /> WARNING: CPU: 0 PID: 5342 at net/core/skbuff.c:7140 skb_splice_from_iter+0x173/0x320<br /> Call Trace:<br /> tcp_sendmsg_locked+0x368/0xe40<br /> siw_tx_hdt+0x695/0xa40 [siw]<br /> siw_qp_sq_process+0x102/0xb00 [siw]<br /> siw_sq_resume+0x39/0x110 [siw]<br /> siw_run_sq+0x74/0x160 [siw]<br /> kthread+0xd2/0x100<br /> ret_from_fork+0x34/0x40<br /> ret_from_fork_asm+0x1a/0x30
