Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，已修复以下漏洞： 固件：coreboot：验证表边界 现有的 中的边界检查将单个条目限制在映射的长度之内。然而， 在映射完整表之前，会用固件提供的头部和表大小替换平台资源的长度。 一个格式错误的表可能导致 32 位大小加法溢出，或者声明超出资源范围的长度，从而导致驱动程序映射并解析资源之外的内存。此外，长度短于固定头部的资源也会被当作包含完整头部进行映射。 修复措施包括：拒绝长度短于固定头部的资源。在验证签名后，要求存在完整头部，使用带溢出检查的方式计算声明的扩展范围，并在重新映射表之前，拒

Vulnerability Title
firmware: coreboot: Validate table bounds
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: firmware: coreboot: Validate table bounds The existing coreboot_table_populate() bounds checks limit individual entries to the mapped length. However, coreboot_table_probe() replaces the platform resource length with header and table sizes supplied by firmware before mapping the full table. A malformed table can overflow the 32-bit size addition or advertise an extent beyond the resource, causing the driver to map and parse memory outside the resource. A resource shorter than the fixed header is also mapped as though it contained a complete header. Reject resources shorter than the fixed header. After validating the signature, require a complete header, calculate the advertised extent with overflow checking, and reject extents beyond the resource before remapping the table.
