Details

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

remoteproc: core: Clear tablesz when rprocshutdown

There is case as below could trigger kernel dump: Use U-Boot to start remote processor(rproc) with resource table published to a fixed address by rproc. After Kernel boots up, stop the rproc, load a new firmware which doesn't have resource table ,and start rproc.

When starting rproc with a firmware not have resource table, memcpy(loaded_table, rproc->cached_table, rproc->table_sz) will trigger dump, because rproc->cachetable is set to NULL during the last stop operation, but rproc->tablesz is still valid.

This issue is found on i.MX8MP and i.MX9.

Dump as below: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 Mem abort info: ESR = 0x0000000096000004 EC = 0x25: DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 FSC = 0x04: level 0 translation fault Data abort info: ISV = 0, ISS = 0x00000004, ISS2 = 0x00000000 CM = 0, WnR = 0, TnD = 0, TagAccess = 0 GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0 user pgtable: 4k pages, 48-bit VAs, pgdp=000000010af63000 [0000000000000000] pgd=0000000000000000, p4d=0000000000000000 Internal error: Oops: 0000000096000004 [#1] PREEMPT SMP Modules linked in: CPU: 2 UID: 0 PID: 1060 Comm: sh Not tainted 6.14.0-rc7-next-20250317-dirty #38 Hardware name: NXP i.MX8MPlus EVK board (DT) pstate: a0000005 (NzCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : _pimemcpygeneric+0x110/0x22c lr : rprocstart+0x88/0x1e0 Call trace: _pimemcpygeneric+0x110/0x22c (P) rprocboot+0x198/0x57c statestore+0x40/0x104 devattrstore+0x18/0x2c sysfskfwrite+0x7c/0x94 kernfsfopwriteiter+0x120/0x1cc vfswrite+0x240/0x378 ksyswrite+0x70/0x108 _arm64syswrite+0x1c/0x28 invokesyscall+0x48/0x10c el0svccommon.constprop.0+0xc0/0xe0 doel0svc+0x1c/0x28 el0svc+0x30/0xcc el0t64synchandler+0x10c/0x138 el0t64sync+0x198/0x19c
