中文标题:
Linux kernel 安全漏洞
英文标题:
f2fs: fix information leak in f2fs_move_inline_dirents()
漏洞描述
中文描述:
Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞，该漏洞源于f2fs_move_inline_dirents函数中的信息泄漏问题。
英文描述:
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't initialize the entire directory block. Fix this by zero-initializing the block. This bug was introduced by commit 4ec17d688d74 ("f2fs: avoid unneeded initializing when converting inline dentry"), which didn't consider the security implications of leaking uninitialized memory to disk. This was found by running xfstest generic/435 on a KMSAN-enabled kernel.
