In the Linux kernel, the following vulnerability has been resolved:
ext2: fix ignored return value of generic_write_sync()
Fix ext2_dio_write_iter() to propagate the error returned by
generic_write_sync() instead of silently discarding it, which could
cause write(2) to return success to userspace on O_SYNC/O_DSYNC files
even when the sync failed.
The correct pattern, already used in ext2_dax_write_iter() in the same
file and in ext4, xfs, f2fs among others, is:
if (ret > 0)
ret = generic_write_sync(iocb, ret);
Found by Linux Verification Center (linuxtesting.org) with SVACE.
