Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
f2fs: avoid format-overflow warning<br />
<br />
With gcc and W=1 option, there&#39;s a warning like this:<br />
<br />
fs/f2fs/compress.c: In function ‘f2fs_init_page_array_cache’:<br />
fs/f2fs/compress.c:1984:47: error: ‘%u’ directive writing between<br />
1 and 7 bytes into a region of size between 5 and 8<br />
[-Werror=format-overflow=]<br />
1984 | sprintf(slab_name, "f2fs_page_array_entry-%u:%u", MAJOR(dev),<br />
MINOR(dev));<br />
| ^~<br />
<br />
String "f2fs_page_array_entry-%u:%u" can up to 35. The first "%u" can up<br />
to 4 and the second "%u" can up to 7, so total size is "24 + 4 + 7 = 35".<br />
slab_name&#39;s size should be 35 rather than 32.
