How to Fix CVE-2026-89592

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-89592, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In the Linux kernel, the following vulnerability has been resolved: accel/rocket: fix NULL dereference and integer overflow in rocket_job_push() rocket_job_push() allocates a temporary array to hold all input and output GEM object pointers: bos = kvmalloc_array(job->in_bo_count + job->out_bo_count, sizeof(void *), GFP_KERNEL); memcpy(bos, job->in_bos, job->in_bo_count * sizeof(void *)); memcpy(&bos[job->in_bo_count], job->out_bos, ...); Two bugs exist: 1. Missing NULL check: if kvmalloc_array() fails, bos is NULL and the subsequent memcpy() dereferences it, causing a kernel NULL pointer dereference. 2. Integer overflow: in_bo_count and out_bo_count are both u32, set directly from userspace-supplied in_bo_handle_count and out_bo_handle_count with no prior validation. Their sum is computed in u32 arithmetic and can wrap to a smaller value, causing the allocation count passed to kvmalloc_array() to be smaller than intended. Subsequent uses still operate on the original counts when copying and locking objects, which may lead to out-of-bounds accesses on the temporary array. Fix by using check_add_overflow() to detect count overflow before the allocation, and adding a NULL check on the allocation result.
