Overview

CVE-2026-72357 is a high-severity vulnerability. It was published on August 15, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

uprobes/x86: Use proper mm_struct in __in_uprobe_trampoline

In the unregister path we use __in_uprobe_trampoline check with

current->mm for the VMA lookup, which is wrong, because we are

in the tracer context, not the traced process.

Add mm_struct pointer argument to __in_uprobe_trampoline and

changing related callers to pass proper mm_struct pointer.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
