CVE-2025-71228

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel related to memory protection on LoongArch platforms. Specifically, the protection map[] was not correctly set for Virtual Memory Areas (VMAs) configured as VM NONE or VM SHARED. On 32-bit platforms, this resulted in pages becoming non-present, leading to a kernel page fault and system instability (Oops). The issue stemmed from using PAGE PROTNONE which is 0, causing incorrect memory protection settings. The fix involves setting the correct protection map[] by replacing PAGE PROTNONE with PAGE PRESENT.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
