Technical description

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

net: sfp: fix memory leak in sfp_probe()

sfp_probe() allocates a memory chunk from sfp with sfp_alloc(). When

devm_add_action() fails, sfp is not freed, which leads to a memory leak.

We should use devm_add_action_or_reset() instead of devm_add_action().

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.
