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\n\n## Affected\n\n- `Linux >= 0e935ae6afcdbe6f0c0aa457ae57feccc63bb9be < d5a019e819a0f0457570416bb2eb5f3321f5be81`\n- `Linux >= 0e935ae6afcdbe6f0c0aa457ae57feccc63bb9be < 3406bfc813a9bbd9c3055795e985f527b7852e8c`\n- `Linux >= 0e935ae6afcdbe6f0c0aa457ae57feccc63bb9be < bb5738957d92c8603a90c9664d34236641c221b2`\n- `Linux >= 0e935ae6afcdbe6f0c0aa457ae57feccc63bb9be < 4e1e3dd88a4cedd5ccc1a3fc3d71e03b70a7a791`\n- `Linux 5.3`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":54,"depthScoreParts":{"impact":53.9,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
