CVE-2022-50013

Summary: CVE-2022-50013 relates to the f2fs (Flash-Friendly File System) code in the Linux kernel. The issue arises from a NAT/NAT bitmap inconsistency that can cause a BUG_ON() in f2fs_new_node_page() when a NAT entry’s blkaddr is not NULL_ADDR while its NAT bitmap marks it free. The vulnerabili...
