What to do
AI-suggested
A fix has been implemented in the Linux kernel to skip allocation of PMD-sized page caches when their size exceeds the maximum supported page cache order. Users should update to the fixed kernel version once available. No additional mitigation steps are indicated.
Description
CVE-2024-41031 is a vulnerability in the Linux kernel's memory management subsystem related to the creation of PMD-sized page caches on ARM64 architectures with a 64KB base page size. The flaw causes errors when the PMD-sized page cache is larger than the maximum supported page cache order, leading to kernel warnings and potential instability. The issue is fixed by skipping the allocation of PMD-sized page caches when their size exceeds the limit, falling back to a regular page cache allocation path.
