"value": "In the Linux kernel, the following vulnerability has been resolved:\n\next2: fix ignored return value of generic_write_sync()\n\nFix ext2_dio_write_iter() to propagate the error returned by\ngeneric_write_sync() instead of silently discarding it, which could\ncause write(2) to return success to userspace on O_SYNC/O_DSYNC files\neven when the sync failed.\n\nThe correct pattern, already used in ext2_dax_write_iter() in the same\nfile and in ext4, xfs, f2fs among others, is:\n if (ret > 0)\n ret = generic_write_sync(iocb, ret);\n\nFound by Linux Verification Center (linuxtesting.org) with SVACE.\n\n[JK: Reflect also filemap_write_and_wait() return value]"
