Overview

CVE-2024-46790 is a medium-severity vulnerability affecting linux linux_kernel. It was published on September 18, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

codetag: debug: mark codetags for poisoned page as empty

When PG_hwpoison pages are freed they are treated differently in

free_pages_prepare() and instead of being released they are isolated.

Page allocation tag counters are decremented at this point since the page

is considered not in use. Later on when such pages are released by

unpoison_memory(), the allocation tag counters will be decremented again

and the following warning gets reported:
