CVE-2022-50271

CVE-2022-50271 affects the Linux kernel’s vhost/vsock code. The issue arises when copying large files over SFTP over vsock, where data sizes commonly reach 32 kB and kmalloc may allocate many 32 kB chunks, leading to a page allocation failure (example: vhost-5837). The root cause is an inefficien...
