CVE ID: | CVE-2023-0459 |
Description: | Copy_from_user on 64-bit versions of the Linux kernel does not implement the __uaccess_begin_nospec allowing a user to bypass the "access_ok" check and pass a kernel pointer to copy_from_user(). This would allow an attacker to leak information. We recommend upgrading beyond commit 74e19ef0ff8061ef55957c3abd71614ef0f42f47 |
Test IDs: | 1.3.6.1.4.1.25623.1.1.1.2.2023.3404 |
