CVE-2023-53820 (CNNVD-202512-1642)
中文标题:
Linux kernel 安全漏洞
英文标题:
loop: loop_set_status_from_info() check before assignment
漏洞描述
中文描述:
Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞，该漏洞源于未检查lo_offset和lo_sizelimit赋值，可能导致溢出错误。
英文描述:
In the Linux kernel, the following vulnerability has been resolved: loop: loop_set_status_from_info() check before assignment In loop_set_status_from_info(), lo->lo_offset and lo->lo_sizelimit should be checked before reassignment, because if an overflow error occurs, the original correct value will be changed to the wrong value, and it will not be changed back. More, the original patch did not solve the problem, the value was set and ioctl returned an error, but the subsequent io used the value in the loop driver, which still caused an alarm: loop_handle_cmd do_req_filebacked loff_t pos = ((loff_t) blk_rq_pos(rq) << 9) + lo->lo_offset; lo_rw_aio cmd->iocb.ki_pos = pos
