In the Linux kernel, the following vulnerability has been resolved:dev/parport: fix the array out-of-bounds riskFixed array out-of-bounds issues caused by sprintfby replacing it with snprintf for safer data copying,ensuring the destination buffer is not overflowed.Below is the stack trace I encountered during the actual issue:[ 66.575408s] [pid:5118,cpu4,QThread,4]Kernel panic - not syncing: stack-protector:Kernel stack is corrupted in: do_hardware_base_addr+0xcc/0xd0 [parport][ 66.575408s] [pid:5118,cpu4,QThread,5]CPU: 4 PID: 5118 Comm:QThread Tainted: G S W O 5.10.97-arm64-desktop #7100.57021.2[ 66.575439s] [pid:5118,cpu4,QThread,6]TGID: 5087 Comm: EFileApp[ 66.575439s] [pid:5118,cpu4,QThread,7]Hardware name: HUAWEI HUAWEI QingYunPGUX-W515x-B081/SP1PANGUXM, BIOS 1.00.07 04/29/2024[ 66.575439s] [pid:5118,cpu4,QThread,8]Call trace:[ 66.575469s] [pid:5118,cpu4,QThread,9] dump_backtrace+0x0/0x1c0[ 66.575469s] [pid:5118,cpu4,QThread,0] show_stack+0x14/0x20[ 66.575469s] [pid:5118,cpu4,QThread,1] dump_stack+0xd4/0x10c[ 66.575500s] [pid:5118,cpu4,QThread,2] panic+0x1d8/0x3bc[ 66.575500s] [pid:5118,cpu4,QThread,3] __stack_chk_fail+0x2c/0x38[ 66.575500s] [pid:5118,cpu4,QThread,4] do_hardware_base_addr+0xcc/0xd0 [parport]
