In the Linux kernel, the following vulnerability has been resolved:
ionic: fix kernel panic due to multi-buffer handling
Currently, the ionicrunxdp() doesn't handle multi-buffer packets properly for XDPTX and XDPREDIRECT. When a jumbo frame is received, the ionicrunxdp() first makes xdp frame with all necessary pages in the rx descriptor. And if the action is either XDPTX or XDPREDIRECT, it should unmap dma-mapping and reset page pointer to NULL for all pages, not only the first page. But it doesn't for SG pages. So, SG pages unexpectedly will be reused. It eventually causes kernel panic.
Oops: general protection fault, probably for non-canonical address 0x504f4e4dbebc64ff: 0000 [#1] PREEMPT SMP NOPTI CPU: 3 PID: 0 Comm: swapper/3 Not tainted 6.10.0-rc3+ #25 RIP: 0010:xdpreturnframe+0x42/0x90 Code: 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 RSP: 0018:ffff99d00122ce08 EFLAGS: 00010202 RAX: 0000000000005453 RBX: ffff8d325f904000 RCX: 0000000000000001 RDX: 00000000670e1000 RSI: 000000011f90d000 RDI: 504f4e4d4c4b4a49 RBP: ffff99d003907740 R08: 0000000000000000 R09: 0000000000000000 R10: 000000011f90d000 R11: 0000000000000000 R12: ffff8d325f904010 R13: 504f4e4dbebc64fd R14: ffff8d3242b070c8 R15: ffff99d0039077c0 FS: 0000000000000000(0000) GS:ffff8d399f780000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f41f6c85e38 CR3: 000000037ac30000 CR4: 00000000007506f0 PKRU: 55555554 Call Trace: <IRQ> ? dieaddr+0x33/0x90 ? excgeneralprotection+0x251/0x2f0 ? asmexcgeneralprotection+0x22/0x30 ? xdpreturnframe+0x42/0x90 ionictxclean+0x211/0x280 [ionic 15881354510e6a9c655c59c54812b319ed2cd015] ionictxcqservice+0xd3/0x210 [ionic 15881354510e6a9c655c59c54812b319ed2cd015] ionictxrxnapi+0x41/0x1b0 [ionic 15881354510e6a9c655c59c54812b319ed2cd015] _napipoll.constprop.0+0x29/0x1b0 netrxaction+0x2c4/0x350 handlesoftirqs+0xf4/0x320 irqexitrcu+0x78/0xa0 common_interrupt+0x77/0x90
