"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: qgroup: fix a wrong length calculation in qgroup_free_reserved_data()\n\nIn that function, we round down the start position and round up the\nending position.\n\nBut during the calculation of @len, we use \"round_up(start + len,\nsectorsize)\", which is the rounded up end position, not the rounded up\nlength.\n\nWhich results a much larger length, and later we are still using\n\"start + len\", which is completely incorrect.\n\nFix it by declaring a local @aligned_start and @aligned_len and use them\ninstead."
