Vulnerability Deep Dive: Exploits and Impacts
This kernel update delivers essential fixes for critical weaknesses in the Linux Human Interface Device (HID) core subsystem:
CVE-2025-38494 (CVSS:4.0 8.5 / CVSS:3.1 7.8): HID Core Bypass Flaw
The Threat: A critical vulnerability allowed potential bypass of security controls within
hid_hw_raw_request. Could attackers leverage this flaw to execute unauthorized commands or exfiltrate sensitive data directly from input devices?Impact: Successful local exploitation could lead to privilege escalation, complete system compromise (Confidentiality, Integrity, Availability loss - C:H/I:H/A:H), and severe breaches of compliance standards.
Reference: bsc#1247350
CVE-2025-38495 (CVSS:4.0 8.5 / CVSS:3.1 7.8): HID Report Buffer Overflow
The Threat: This flaw stemmed from insufficient buffer allocation handling related to HID report IDs. Malicious actors could potentially craft inputs causing buffer overflows.
Impact: Similar to CVE-2025-38494, this vulnerability enabled local attackers to achieve privilege escalation and full system control (C:H/I:H/A:H), posing a direct threat to data security and operational continuity.
Reference: bsc#1247351

Frequently Asked Questions (FAQ): SUSE Kernel Security Update
Q1: How urgent is applying this SUSE kernel patch?
A: Extremely urgent. Both CVE-2025-38494 and CVE-2025-38495 carry CVSS v4 scores of 8.5 (High severity), indicating significant risk of local privilege escalation leading to complete system compromise. Delay increases exploit potential.
Q2: Does this update require a system reboot?
A: For systems using SUSE Linux Enterprise Live Patching, applying this specific kernel live patch typically avoids a full reboot, significantly reducing downtime. Systems without live patching enabled will require a reboot. (Learn more about SUSE Live Patching benefits [Internal Link - Concept: SUSE Live Patching Explained]).
Q3: Are cloud instances of SUSE Linux Enterprise affected?
A: Yes. SUSE Linux Enterprise Server instances running SP6 or SP7 kernels in major cloud platforms (AWS, Azure, GCP) are affected and must be patched using the provided methods or cloud-specific update mechanisms.
Q4: What are the consequences of not patching these HID vulnerabilities?
A: Unpatched systems are vulnerable to local attackers gaining root privileges. This can lead to data theft (confidentiality breach), system manipulation or destruction (integrity/availability breach), malware installation, and non-compliance with security regulations, potentially resulting in significant financial and reputational damage.
Q5: Where can I find detailed technical analysis of these CVEs?
A: Refer to the official SUSE CVE pages linked above (CVE-2025-38494, CVE-2025-38495) and the National Vulnerability Database (NVD) entries once published. SUSE's bug reports (bsc#1247350, bsc#1247351) also contain technical details.
