GHSA-82F5-GHC6-RJ5C

Vulnerability from github – Published: 2023-07-06 21:15 – Updated: 2024-04-04 05:46

Details

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

Severity ?

6.5 (Medium)
