In the Linux kernel before 6.2, mm/memory-tiers.c misinterprets the alloc_memory_type return value (expects it to be NULL in the error case, whereas it is actually an error pointer).

Severity ?

CVE-2023-23005 (GCVE-0-2023-23005)

Vulnerability from cvelistv5 – Published: 2023-03-01 00:00 – Updated: 2025-03-19 18:12

Summary

In the Linux kernel before 6.2, mm/memory-tiers.c misinterprets the alloc_memory_type return value (expects it to be NULL in the error case, whereas it is actually an error pointer). NOTE: this is disputed by third parties because there are no realistic cases in which a user can cause the alloc_memory_type error case to be reached.

Severity ?

5.5 (Medium)
