CVE-2022-49364

CVE-2022-49364 : In the Linux kernel, a f2fs inode eviction bug was fixed. The root cause is that the inode node and the dnode share the same nid, causing dnode truncation to invalidate the NAT entry during f2fs_evict_inode() and leaving the inode marked dirty. The fix clears the dirty flag on th...
