一、漏洞信息
 漏洞编号：[CVE-2022-48830](https://nvd.nist.gov/vuln/detail/CVE-2022-48830)
 漏洞归属组件：[kernel](https://gitee.com/src-openeuler/kernel)
 漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.0,6.1.14,6.1.19,6.1.5,6.1.6,6.1.8,6.4.0,6.6.0
 CVSS V2.0分值：
  BaseScore：0.0 Low
  Vector：CVSS：2.0/
 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:can: isotp: fix potential CAN frame reception race in isotp_rcv()When receiving a CAN frame the current code logic does not considerconcurrently receiving processes which do not show up in real worldusage.Ziyang Xuan writes:The following syz problem is one of the scenarios. so->rx.len ischanged by isotp_rcv_ff() during isotp_rcv_cf(), so->rx.len equals0 before alloc_skb() and equals 4096 after alloc_skb(). That willtrigger skb_over_panic() in skb_put().=======================================================CPU: 1 PID: 19 Comm: ksoftirqd/1 Not tainted 5.16.0-rc8-syzkaller #0RIP: 0010:skb_panic+0x16c/0x16e net/core/skbuff.c:113Call Trace: <TASK> skb_over_panic net/core/skbuff.c:118 [inline] skb_put.cold+0x24/0x24 net/core/skbuff.c:1990 isotp_rcv_cf net/can/isotp.c:570 [inline] isotp_rcv+0xa38/0x1e30 net/can/isotp.c:668 deliver net/can/af_can.c:574 [inline] can_rcv_filter+0x445/0x8d0 net/can/af_can.c:635 can_receive+0x31d/0x580 net/can/af_can.c:665 can_rcv+0x120/0x1c0 net/can/af_can.c:696 __netif_receive_skb_one_core+0x114/0x180 net/core/dev.c:5465 __netif_receive_skb+0x24/0x1b0 net/core/dev.c:5579Therefore we make sure the state changes and data structures stayconsistent at CAN frame reception time by adding a spin_lock inisotp_rcv(). This fixes the issue reported by syzkaller but does notaffect real world operation.
