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 <41> 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 <IRQ>\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","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-476"],"references":["https://git.kernel.org/stable/c/8ae401525ae84228a8986bb369224a6224e4d22f","https://git.kernel.org/stable/c/e3f02f32a05009a688a87f5799e049ed6b55bab5","https://git.kernel.org/stable/c/8ae401525ae84228a8986bb369224a6224e4d22f","https://git.kernel.org/stable/c/e3f02f32a05009a688a87f5799e049ed6b55bab5"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:53:51.317825789+00:00"},"epss":{"cve":"CVE-2024-42083","score":0.00335,"percentile":0.26911,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
