Kerentanan Release of Invalid Pointer or Reference pada linux kernel. Skor CVSS 3.1 5.5 (Medium) menurut NVD.
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
