{"id":"DEBIAN-CVE-2022-49364","details":"In the Linux kernel, the following vulnerability has been resolved:  f2fs: fix to clear dirty inode in f2fs_evict_inode()  As Yanming reported in bugzilla:  https://bugzilla.kernel.org/show_bug.cgi?id=215904  The kernel message is shown below:  kernel BUG at fs/f2fs/inode.c:825!
