How to Fix CVE-2026-81014

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-2026-81014, 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: platform/x86: hp-bioscfg: fix heap OOB read in sk_store() and kek_store() sk_store() and kek_store() strip a trailing newline from the sysfs write before allocating the key buffer: length = count; if (buf[length - 1] == '\n') length--; bioscfg_drv.spm_data.signing_key = kmemdup(buf, length, GFP_KERNEL); but then pass the original "count" (not "length") as the copy size to hp_wmi_perform_query(), which memcpy()s that many bytes out of the "length"-sized allocation, reading one byte past it whenever the write ends in a newline, the normal case for a shell "echo" into sysfs. KASAN confirms this directly: BUG: KASAN: slab-out-of-bounds in hp_wmi_perform_query+0x1e9/0x460 [hp_bioscfg] Read of size 28 at addr ffff88813c8e2b80 by task python3/16022 ... sk_store+0xa7/0x240 [hp_bioscfg] kernfs_fop_write_iter+0x3e1/0x5d0 ... The buggy address is located 0 bytes inside of allocated 27-byte region [ffff88813c8e2b80, ffff88813c8e2b9b) Reproduced identically for kek_store, and at multiple write sizes (28, 57, 201 bytes), each time reading exactly one byte past a kmemdup() allocation one byte smaller than the write. Fix by passing "length" instead of "count" to hp_wmi_perform_query() in both functions.
