  "description": "In the Linux kernel, the following vulnerability has been resolved:  Add exception protection processing for vd in axi_chan_handle_err function  Since there is no protection for vd, a kernel panic will be triggered here in exceptional cases.  You can refer to the processing of axi_chan_block_xfer_complete function  The triggered kernel panic is as follows:  [   67.848444] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000060 [   67.848447] Mem abort info: [   67.848449]   ESR = 0x96000004 [   67.848451]   EC = 0x25: DABT (current EL), IL = 32 bits [   67.848454]   SET = 0, FnV = 0 [   67.848456]   EA = 0, S1PTW = 0 [   67.848458] Data abort info: [   67.848460]   ISV = 0, ISS = 0x00000004 [   67.848462]   CM = 0, WnR = 0 [   67.848465] user pgtable: 4k pages, 48-bit VAs, pgdp=00000800c4c0b000 [   67.848468] [0000000000000060] pgd=0000000000000000, p4d=0000000000000000 [   67.848472] Internal error: Oops: 96000004 [#1] SMP [   67.848475] Modules linked in: dmatest [   67.848479] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 5.10.100-emu_x2rc\u002B #11 [   67.848483] pstate: 62000085 (nZCv daIf -PAN -UAO \u002BTCO BTYPE=--) [   67.848487] pc : axi_chan_handle_err\u002B0xc4/0x230 [   67.848491] lr : axi_chan_handle_err\u002B0x30/0x230 [   67.848493] sp : ffff0803fe55ae50 [   67.848495] x29: ffff0803fe55ae50 x28: ffff800011212200 [   67.848500] x27: ffff0800c42c0080 x26: ffff0800c097c080 [   67.848504] x25: ffff800010d33880 x24: ffff80001139d850 [   67.848508] x23: ffff0800c097c168 x22: 0000000000000000 [   67.848512] x21: 0000000000000080 x20: 0000000000002000 [   67.848517] x19: ffff0800c097c080 x18: 0000000000000000 [   67.848521] x17: 0000000000000000 x16: 0000000000000000 [   67.848525] x15: 0000000000000000 x14: 0000000000000000 [   67.848529] x13: 0000000000000000 x12: 0000000000000040 [   67.848533] x11: ffff0800c0400248 x10: ffff0800c040024a [   67.848538] x9 : ffff800010576cd4 x8 : ffff0800c0400270 [   67.848542] x7 : 0000000000000000 x6 : ffff0800c04003e0 [   67.848546] x5 : ffff0800c0400248 x4 : ffff0800c4294480 [   67.848550] x3 : dead000000000100 x2 : dead000000000122 [   67.848555] x1 : 0000000000000100 x0 : ffff0800c097c168 [   67.848559] Call trace: [   67.848562]  axi_chan_handle_err\u002B0xc4/0x230 [   67.848566]  dw_axi_dma_interrupt\u002B0xf4/0x590 [   67.848569]  __handle_irq_event_percpu\u002B0x60/0x220 [   67.848573]  handle_irq_event\u002B0x64/0x120 [   67.848576]  handle_fasteoi_irq\u002B0xc4/0x220 [   67.848580]  __handle_domain_irq\u002B0x80/0xe0 [   67.848583]  gic_handle_irq\u002B0xc0/0x138 [   67.848585]  el1_irq\u002B0xc8/0x180 [   67.848588]  arch_cpu_idle\u002B0x14/0x2c [   67.848591]  default_idle_call\u002B0x40/0x16c [   67.848594]  do_idle\u002B0x1f0/0x250 [   67.848597]  cpu_startup_entry\u002B0x2c/0x60 [   67.848600]  rest_init\u002B0xc0/0xcc [   67.848603]  arch_call_rest_init\u002B0x14/0x1c [   67.848606]  start_kernel\u002B0x4cc/0x500 [   67.848610] Code: eb0002ff 9a9f12d6 f2fbd5a2 f2fbd5a3 (a94602c1) [   67.848613] ---[ end trace 585a97036f88203a ]---",
