Linux Kernel vulnerability analysis and mitigation
Overview
CVE-2025-38458 is a vulnerability discovered in the Linux kernel that involves a NULL pointer dereference in the vcc_sendmsg() function within the ATM CLIP implementation. The vulnerability was disclosed on July 25, 2025 (NVD).
Technical details
The vulnerability occurs in the ATM (Asynchronous Transfer Mode) CLIP (Classical IP over ATM) implementation where the atmarpddevops does not implement the send method. This leads to a NULL pointer dereference in the vcc_sendmsg() function, which can cause a kernel crash. The issue manifests in the net/atm/common.c file at line 644 (NVD).
Impact
When exploited, this vulnerability results in a kernel crash, causing a denial of service condition. This is evidenced by the kernel oops message showing a NULL pointer dereference at address 0x0 (NVD).
Mitigation and workarounds
The vulnerability has been resolved in the Linux kernel through a fix that addresses the NULL pointer dereference in the vcc_sendmsg() function (NVD).
