CVE-2025-27723: Denial of Service in Intel(R) Ethernet 800 series
Use after free for some Linux kernel driver for the Intel(R) Ethernet 800 series before version 2.3.14 within Ring 0: Kernel may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (high) impacts.
AI Analysis
Technical Summary
This vulnerability involves a use-after-free condition in the Linux kernel driver for Intel(R) Ethernet 800 series network adapters prior to version 2.3.14. An unprivileged local attacker with authentication can trigger a denial of service by exploiting this flaw, which affects system availability. The attack complexity is low and does not require user interaction or special internal knowledge. The vulnerability does not affect confidentiality or integrity but can cause system crashes or instability due to resource misuse in kernel space. The CVSS 4.0 vector indicates local attack vector, low attack complexity, privileged requirement, no user interaction, and high impact on availability. No vendor advisory or patch information is currently available, and no exploits are known in the wild.
Potential Impact
The vulnerability impacts system availability by enabling denial of service conditions through a use-after-free bug in the kernel driver. Confidentiality and integrity are not affected. Successful exploitation may cause system crashes or instability, disrupting normal operations on affected systems running vulnerable driver versions.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, limit access to systems with affected Intel(R) Ethernet 800 series drivers to trusted users only. Monitor for updates from Intel regarding patches or workarounds. No vendor advisory or official remediation information is currently available.
