Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Linux kernel是美国Linux基金会开源的一个操作系统内核。 Linux kernel 6.6.145之前版本、6.12.97之前版本、6.18.40之前版本和7.1.5之前版本存在安全漏洞，该漏洞源于dm-ioctl的list_version_get_info函数中sizeof(tt->version)为12字节，但代码向输出缓冲区写入16字节，可能导致缓冲区溢出。

Vulnerability Title
dm-ioctl: fix a possible overflow in list_version_get_info
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: dm-ioctl: fix a possible overflow in list_version_get_info sizeof(tt->version) is 12 bytes, but the code writes 16 bytes into the output buffer - info->vers->version[0], info->vers->version[1], info->vers->version[2] and info->vers->next. This can cause buffer overflow. Fix this buffer overflow by replacing "sizeof(tt->version)" with "sizeof(struct dm_target_versions)".
