CVE-2024-56782— ACPI: x86: Add adev NULL check to acpi_quirk_skip_serdev_enumeration()

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.

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ACPI模块的acpi_quirk_skip_serdev_enumeration函数中，未对adev进行NULL检查，直接调用acpi_dev_hid_match，可能导致NULL指针解引用，影响系统的稳定性和安全性。

Vulnerability Title
ACPI: x86: Add adev NULL check to acpi_quirk_skip_serdev_enumeration()
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: ACPI: x86: Add adev NULL check to acpi_quirk_skip_serdev_enumeration() acpi_dev_hid_match() does not check for adev == NULL, dereferencing it unconditional. Add a check for adev being NULL before calling acpi_dev_hid_match(). At the moment acpi_quirk_skip_serdev_enumeration() is never called with a controller_parent without an ACPI companion, but better safe than sorry.
