Vulnerability Description
A race problem was seen in the vt_k_ioctl in drivers/tty/vt/vt_ioctl.c in the Linux kernel, which may cause an out of bounds read in vt as the write access to vc_mode is not protected by lock-in vt_ioctl (KDSETMDE). The highest threat from this vulnerability is to data confidentiality.

Linux kernel 缓冲区错误漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
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 存在缓冲区错误漏洞，该漏洞源于 drivers/tty/vt/vt_ioctl.c 中的 vt_k_ioctl 中存在一个竞争条件问题。这可能导致 vt 中的越界读取，因为对 vc_mode 的写访问不受锁定 vt_ioctl (KDSETMDE) 的保护。
