Summary
ionic: fix kernel panic in XDP_TX action
Details

In the Linux kernel, the following vulnerability has been resolved:

ionic: fix kernel panic in XDP_TX action

In the XDPTX path, ionic driver sends a packet to the TX path with rx page and corresponding dma address. After tx is done, ionictx_clean() frees that page. But RX ring buffer isn't reset to NULL. So, it uses a freed page, which causes kernel panic.

BUG: unable to handle page fault for address: ffff8881576c110c PGD 773801067 P4D 773801067 PUD 87f086067 PMD 87efca067 PTE 800ffffea893e060 Oops: Oops: 0000 [#1] PREEMPT SMP DEBUGPAGEALLOC KASAN NOPTI CPU: 1 PID: 25 Comm: ksoftirqd/1 Not tainted 6.9.0+ #11 Hardware name: ASUS System Product Name/PRIME Z690-P D4, BIOS 0603 11/01/2021 RIP: 0010:bpfprogf0b8caeac1068a55balanceringress+0x3b/0x44f Code: 00 53 41 55 41 56 41 57 b8 01 00 00 00 48 8b 5f 08 4c 8b 77 00 4c 89 f7 48 83 c7 0e 48 39 d8 RSP: 0018:ffff888104e6fa28 EFLAGS: 00010283 RAX: 0000000000000002 RBX: ffff8881576c1140 RCX: 0000000000000002 RDX: ffffffffc0051f64 RSI: ffffc90002d33048 RDI: ffff8881576c110e RBP: ffff888104e6fa88 R08: 0000000000000000 R09: ffffed1027a04a23 R10: 0000000000000000 R11: 0000000000000000 R12: ffff8881b03a21a8 R13: ffff8881589f800f R14: ffff8881576c1100 R15: 00000001576c1100 FS: 0000000000000000(0000) GS:ffff88881ae00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: ffff8881576c110c CR3: 0000000767a90000 CR4: 00000000007506f0 PKRU: 55555554 Call Trace: <TASK> ? _die+0x20/0x70 ? pagefaultoops+0x254/0x790 ? _pfxpagefaultoops+0x10/0x10 ? _pfxisprefetch.constprop.0+0x10/0x10 ? searchbpfextables+0x165/0x260 ? fixupexception+0x4a/0x970 ? excpagefault+0xcb/0xe0 ? asmexcpagefault+0x22/0x30 ? 0xffffffffc0051f64 ? bpfprogf0b8caeac1068a55balanceringress+0x3b/0x44f ? dorawspinunlock+0x54/0x220 ionicrxservice+0x11ab/0x3010 [ionic 9180c3001ab627d82bbc5f3ebe8a0decaf6bb864] ? ionictxclean+0x29b/0xc60 [ionic 9180c3001ab627d82bbc5f3ebe8a0decaf6bb864] ? _pfxionictxclean+0x10/0x10 [ionic 9180c3001ab627d82bbc5f3ebe8a0decaf6bb864] ? _pfxionicrxservice+0x10/0x10 [ionic 9180c3001ab627d82bbc5f3ebe8a0decaf6bb864] ? ionictxcqservice+0x25d/0xa00 [ionic 9180c3001ab627d82bbc5f3ebe8a0decaf6bb864] ? _pfxionicrxservice+0x10/0x10 [ionic 9180c3001ab627d82bbc5f3ebe8a0decaf6bb864] ioniccqservice+0x69/0x150 [ionic 9180c3001ab627d82bbc5f3ebe8a0decaf6bb864] ionictxrxnapi+0x11a/0x540 [ionic 9180c3001ab627d82bbc5f3ebe8a0decaf6bb864] _napipoll.constprop.0+0xa0/0x440 netrxaction+0x7e7/0xc30 ? _pfxnetrx_action+0x10/0x10
