How to Fix CVE-2026-64571

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-2026-64571, 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: wifi: p54: validate RX frame length in p54_rx_eeprom_readback() p54_rx_eeprom_readback() copies the requested EEPROM slice out of a device-supplied readback frame without checking that the skb actually holds that many bytes. Commit da1b9a55ff11 ("wifi: p54: prevent buffer-overflow in p54_rx_eeprom_readback()") closed the destination overflow by copying a fixed priv->eeprom_slice_size (and rejecting a mismatched advertised len), but the source side is still unbounded: nothing verifies the frame is long enough to supply that many bytes. A malicious USB device can send a short frame whose advertised len matches priv->eeprom_slice_size while the payload is truncated. The equality check passes and memcpy() reads past the end of the skb, leaking adjacent heap: BUG: KASAN: slab-out-of-bounds in p54_rx (drivers/net/wireless/intersil/p54/txrx.c:507) Read of size 1016 at addr ffff88800f077114 by task swapper/0/0 Call Trace: <IRQ> ... __asan_memcpy (mm/kasan/shadow.c:105) p54_rx (drivers/net/wireless/intersil/p54/txrx.c:507) p54u_rx_cb (drivers/net/wireless/intersil/p54/p54usb.c:163) __usb_hcd_giveback_urb (drivers/usb/core/hcd.c:1657) dummy_timer (drivers/usb/gadget/udc/dummy_hcd.c:2005) ... </IRQ> The buggy address belongs to the object at ffff88800f0770c0 which belongs to the cache skbuff_small_head of size 704 The buggy address is located 84 bytes inside of allocated 704-byte region [ffff88800f0770c0, ffff88800f077380) Check that the slice fits in the skb before copying.
