Quick assessment

Affected
Linux Linux
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.

在 Linux 内核中，以下漏洞已得到修复： ACPI：RISC-V：修复 riscv_acpi_add_prt_dep() 中的循环处理 riscv_acpi_add_prt_dep() 函数中的循环包含一些以存疑——甚至可能是完全错误——方式处理的错误条件，即通过 继续循环（这会导致跳过并遗漏将条目指针更新为指向下一个条目的操作）。 将该循环重写为 for 循环（以正确处理 continue 的行为），并使用辅助函数包裹条件判断和更新语句，使代码更加清晰。

Vulnerability Title
ACPI: RISC-V: Fix riscv_acpi_add_prt_dep() loop handling
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: ACPI: RISC-V: Fix riscv_acpi_add_prt_dep() loop handling The loop in riscv_acpi_add_prt_dep() includes error conditions that are handled in a dubious - if not outright wrong - way, by continuining the loop (which skips and misses the entry pointer update to point to the next entry). Rewrite the loop as a for loop (that handles the continuation correctly) and wrap the condition and update statements using helper functions to make it cleaner.
