  "description": "In the Linux kernel, the following vulnerability has been resolved:  f2fs: fix information leak in f2fs_move_inline_dirents()  When converting an inline directory to a regular one, f2fs is leaking uninitialized memory to disk because it doesn\u0027t initialize the entire directory block.  Fix this by zero-initializing the block.  This bug was introduced by commit 4ec17d688d74 (\u0022f2fs: avoid unneeded initializing when converting inline dentry\u0022), which didn\u0027t consider the security implications of leaking uninitialized memory to disk.  This was found by running xfstest generic/435 on a KMSAN-enabled kernel.",
