{"id":"CVE-2024-42083","summary":"ionic: fix kernel panic due to multi-buffer handling","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nionic: fix kernel panic due to multi-buffer handling\n\nCurrently, the ionic_run_xdp() doesn't handle multi-buffer packets\nproperly for XDP_TX and XDP_REDIRECT.\nWhen a jumbo frame is received, the ionic_run_xdp() first makes xdp\nframe with all necessary pages in the rx descriptor.\nAnd if the action is either XDP_TX or XDP_REDIRECT, it should unmap\ndma-mapping and reset page pointer to NULL for all pages, not only the\nfirst page.\nBut it doesn't for SG pages. So, SG pages unexpectedly will be reused.\nIt eventually causes kernel panic.\n\nOops: general protection fault, probably for non-canonical address 0x504f4e4dbebc64ff: 0000 [#1] PREEMPT SMP NOPTI\nCPU: 3 PID: 0 Comm: swapper/3 Not tainted 6.10.0-rc3+ #25\nRIP: 0010:xdp_return_frame+0x42/0x90\nCode: 01 75 12 5b 4c 89 e6 5d 31 c9 41 5c 31 d2 41 5d e9 73 fd ff ff 44 8b 6b 20 0f b7 43 0a 49 81 ed 68 01 00 00 49 29 c5 49 01 fd \u003c41\u003e 80 7d0\nRSP: 0018:ffff99d00122ce08 EFLAGS: 00010202\nRAX: 0000000000005453 RBX: ffff8d325f904000 RCX: 0000000000000001\nRDX: 00000000670e1000 RSI: 000000011f90d000 RDI: 504f4e4d4c4b4a49\nRBP: ffff99d003907740 R08: 0000000000000000 R09: 0000000000000000\nR10: 000000011f90d000 R11: 0000000000000000 R12: ffff8d325f904010\nR13: 504f4e4dbebc64fd R14: ffff8d3242b070c8 R15: ffff99d0039077c0\nFS:  0000000000000000(0000) GS:ffff8d399f780000(0000) knlGS:0000000000000000\nCS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: 00007f41f6c85e38 CR3: 000000037ac30000 CR4: 00000000007506f0\nPKRU: 55555554\nCall Trace:\n \u003cIRQ\u003e\n ? die_addr+0x33/0x90\n ? exc_general_protection+0x251/0x2f0\n ? asm_exc_general_protection+0x22/0x30\n ? xdp_return_frame+0x42/0x90\n ionic_tx_clean+0x211/0x280 [ionic 15881354510e6a9c655c59c54812b319ed2cd015]\n ionic_tx_cq_service+0xd3/0x210 [ionic 15881354510e6a9c655c59c54812b319ed2cd015]\n ionic_txrx_napi+0x41/0x1b0 [ionic 15881354510e6a9c655c59c54812b319ed2cd015]\n __napi_poll.constprop.0+0x29/0x1b0\n net_rx_action+0x2c4/0x350\n handle_softirqs+0xf4/0x320\n irq_exit_rcu+0x78/0xa0\n common_interrupt+0x77/0x90","modified":"2026-04-02T12:17:44.108830Z","published":"2024-07-29T15:54:44.106Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/42xxx/CVE-2024-42083.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/8ae401525ae84228a8986bb369224a6224e4d22f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e3f02f32a05009a688a87f5799e049ed6b55bab5"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/42xxx/CVE-2024-42083.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-42083"},{"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":"5377805dc1c02ad3721a9256f0eef9b4813952e7"},{"fixed":"8ae401525ae84228a8986bb369224a6224e4d22f"},{"fixed":"e3f02f32a05009a688a87f5799e049ed6b55bab5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-42083.json"}}],"schema_version":"1.7.5"}
