{"id":"AZL-54646","summary":"CVE-2024-53094 affecting package kernel for versions less than 6.6.64.2-1","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":"2026-04-01T05:18:21.139170Z","published":"2024-11-21T19:15:12Z","upstream":["CVE-2024-53094"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-53094"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.64.2-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-54646.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"}]}
