{"id":"CVE-2024-53094","summary":"RDMA/siw: Add sendpage_ok() check to disable MSG_SPLICE_PAGES","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/siw: Add sendpage_ok() check to disable MSG_SPLICE_PAGES\n\nWhile running ISER over SIW, the initiator machine encounters a warning\nfrom skb_splice_from_iter() indicating that a slab page is being used in\nsend_page. To address this, it is better to add a sendpage_ok() check\nwithin the driver itself, and if it returns 0, then MSG_SPLICE_PAGES flag\nshould be disabled before entering the network stack.\n\nA similar issue has been discussed for NVMe in this thread:\nhttps://lore.kernel.org/all/20240530142417.146696-1-ofir.gal@volumez.com/\n\n  WARNING: CPU: 0 PID: 5342 at net/core/skbuff.c:7140 skb_splice_from_iter+0x173/0x320\n  Call Trace:\n   tcp_sendmsg_locked+0x368/0xe40\n   siw_tx_hdt+0x695/0xa40 [siw]\n   siw_qp_sq_process+0x102/0xb00 [siw]\n   siw_sq_resume+0x39/0x110 [siw]\n   siw_run_sq+0x74/0x160 [siw]\n   kthread+0xd2/0x100\n   ret_from_fork+0x34/0x40\n   ret_from_fork_asm+0x1a/0x30","modified":"2026-04-16T04:34:23.457365300Z","published":"2024-11-21T18:17:10.600Z","related":["SUSE-SU-2024:4314-1","SUSE-SU-2024:4316-1","SUSE-SU-2024:4318-1","SUSE-SU-2024:4387-1","SUSE-SU-2025:20163-1","SUSE-SU-2025:20164-1","SUSE-SU-2025:20246-1","SUSE-SU-2025:20247-1","USN-7276-1","USN-7277-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/53xxx/CVE-2024-53094.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3406bfc813a9bbd9c3055795e985f527b7852e8c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4e1e3dd88a4cedd5ccc1a3fc3d71e03b70a7a791"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bb5738957d92c8603a90c9664d34236641c221b2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/53xxx/CVE-2024-53094.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-53094"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0e935ae6afcdbe6f0c0aa457ae57feccc63bb9be"},{"fixed":"3406bfc813a9bbd9c3055795e985f527b7852e8c"},{"fixed":"bb5738957d92c8603a90c9664d34236641c221b2"},{"fixed":"4e1e3dd88a4cedd5ccc1a3fc3d71e03b70a7a791"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-53094.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
