In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix to avoid potential memory corruption in __update_iostat_latency()
Add iotype sanity check to avoid potential memory corruption.
This is to fix the compile error below:
fs/f2fs/iostat.c:231 __update_iostat_latency() error: buffer overflow
'io_lat->peak_lat[type]' 3 type;
216 struct f2fs_sb_info *sbi = iostat_ctx->sbi;
217 struct iostat_lat_info *io_lat = sbi->iostat_io_lat;
218 unsigned long flags;
219
220 if (!sbi->iostat_enable)
221 return;
222
223 ts_diff = jiffies - iostat_ctx->submit_ts;
224 if (page_type >= META_FLUSH)
^^^^^^^^^^
225 page_type = META;
226
227 spin_lock_irqsave(&sbi->iostat_lat_lock, flags);
@228 io_lat->sum_lat[type][page_type] += ts_diff;
^^^^^^^^^
Mixup between META_FLUSH and NR_PAGE_TYPE leads to memory corruption.
