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

iommu/arm-smmu-v3: Manage teardown with devm

arm_smmu_device_remove() manually frees the IOPF queue, destroys the vmid_map and disables the device, while the IRQs and queues are devm managed. devm unwinds only after remove() returns, so the cleanup runs in the wrong order. The IOPF queue is freed before the event-queue IRQ whose handler uses it.

Manage all of it with devm so the unwind order is correct. Free the IOPF queue and vmid_map via devm actions, and disable the device from one registered after arm_smmu_device_reset().

This is also a prerequisite for fixing a Tegra241 CMDQV CMD_SYNC use-after-free in the subsequent patch.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Attack Technique

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
