CVE-2026-89582

/// Technical description

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

bnx2x: fix double free in bnx2x_init_firmware() error path

bnx2x_init_firmware() frees bp->init_ops, bp->init_data and

bp->init_ops_offsets in its error path without setting them to NULL.

The cleanup function bnx2x_release_firmware() frees the same three

pointers unconditionally, so if init_firmware fails and

release_firmware is later called (e.g. from __bnx2x_remove or through

the function state machine), all three are freed a second time.

Set each pointer to NULL after kfree() in the error path so that the

subsequent kfree(NULL) in bnx2x_release_firmware() is a safe no-op.

/// 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.
