CVE-2024-56368
MediumSummary
In the Linux kernel, an overflow in the ring-buffer's __rb_map_vma function was fixed, which occurred when calculating the number of pages (nr_pages). A check was added before the calculation to avoid the issue.
Risk Assessment
The overflow could lead to incorrect memory mapping, potentially causing system crashes or security breaches.
Recommendation
Apply the Linux kernel patch to prevent overflow in the ring-buffer and ensure system stability.
