 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:remoteproc: core: Clear table_sz when rproc_shutdownThere is case as below could trigger kernel dump:Use U-Boot to start remote processor(rproc) with resource tablepublished 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)` willtrigger dump, because rproc->cache_table is set to NULL during the laststop operation, but rproc->table_sz 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 0000000000000000Mem 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 faultData abort info:  ISV = 0, ISS = 0x00000004, ISS2 = 0x00000000  CM = 0, WnR = 0, TnD = 0, TagAccess = 0  GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0user pgtable: 4k pages, 48-bit VAs, pgdp=000000010af63000[0000000000000000] pgd=0000000000000000, p4d=0000000000000000Internal error: Oops: 0000000096000004 [#1] PREEMPT SMPModules linked in:CPU: 2 UID: 0 PID: 1060 Comm: sh Not tainted 6.14.0-rc7-next-20250317-dirty #38Hardware name: NXP i.MX8MPlus EVK board (DT)pstate: a0000005 (NzCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--)pc : __pi_memcpy_generic+0x110/0x22clr : rproc_start+0x88/0x1e0Call trace: __pi_memcpy_generic+0x110/0x22c (P) rproc_boot+0x198/0x57c state_store+0x40/0x104 dev_attr_store+0x18/0x2c sysfs_kf_write+0x7c/0x94 kernfs_fop_write_iter+0x120/0x1cc vfs_write+0x240/0x378 ksys_write+0x70/0x108 __arm64_sys_write+0x1c/0x28 invoke_syscall+0x48/0x10c el0_svc_common.constprop.0+0xc0/0xe0 do_el0_svc+0x1c/0x28 el0_svc+0x30/0xcc el0t_64_sync_handler+0x10c/0x138 el0t_64_sync+0x198/0x19cClear rproc->table_sz to address the issue.
