CVE-2025-68289 — usb: gadget: f_eem: Fix memory leak in eem_unwrap

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: f_eem: Fix memory leak in eem_unwrap The existing code did not handle the failure case of usb_ep_queue in the command path, potentially leading to memory leaks. Improve error handling to free all allocated resources on usb_ep_queue failure. This patch continues to use goto logic for error handling, as the existing error handling is complex and not easily adaptable to auto-cleanup helpers. kmemleak results: unreferenced object 0xffffff895a512300 (size 240): backtrace: slab_post_alloc_hook+0xbc/0x3a4 kmem_cache_alloc+0x1b4/0x358 skb_clone+0x90/0xd8 eem_unwrap+0x1cc/0x36c unreferenced object 0xffffff8a157f4000 (size 256): backtrace: slab_post_alloc_hook+0xbc/0x3a4 __kmem_cache_alloc_node+0x1b4/0x2dc kmalloc_trace+0x48/0x140 dwc3_gadget_ep_alloc_request+0x58/0x11c usb_ep_alloc_request+0x40/0xe4 eem_unwrap+0x204/0x36c unreferenced object 0xffffff8aadbaac00 (size 128): backtrace: slab_post_alloc_hook+0xbc/0x3a4 __kmem_cache_alloc_node+0x1b4/0x2dc __kmalloc+0x64/0x1a8 eem_unwrap+0x218/0x36c unreferenced object 0xffffff89ccef3500 (size 64): backtrace: slab_post_alloc_hook+0xbc/0x3a4 __kmem_cache_alloc_node+0x1b4/0x2dc kmalloc_trace+0x48/0x140 eem_unwrap+0x238/0x36c

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.2% (30-day exploitation probability)+2

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Linux Linux).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.

What should defenders know first?

CVE-2025-68289 is "usb: gadget: f_eem: Fix memory leak in eem_unwrap", rated Unknown. It affects Linux (Linux); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. EPSS 0.21% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
