一、漏洞信息
 漏洞编号：[CVE-2022-49258](https://nvd.nist.gov/vuln/detail/CVE-2022-49258)
 漏洞归属组件：[kernel](https://gitee.com/src-openeuler/kernel)
 漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.19,6.1.8,6.4.0,6.6.0
 CVSS V3.0分值：
  BaseScore：7.8 High
  Vector：CVSS：3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:crypto: ccree - Fix use after free in cc_cipher_exit()kfree_sensitive(ctx_p->user.key) will free the ctx_p->user.key. Butctx_p->user.key is still used in the next line, which will lead to ause after free.We can call kfree_sensitive() after dev_dbg() to avoid the uaf.
