HIGH

Linux Kernel 4.17-5.10.110, 5.11-5.15.33, 5.16-5.16.19, 5.17-5.17.2 - Use-After-Free in cc_cipher_exit()

Title source: llm
STIX 2.1

Description

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. But ctx_p->user.key is still used in the next line, which will lead to a use after free. We can call kfree_sensitive() after dev_dbg() to avoid the uaf.
