A memory management flaw in the Linux kernel Panthor driver allows authenticated local attackers to trigger buffer overflows, potentially leading to arbitrary code execution.

The vulnerability occurs in the panthor_fw_load_section_entry function, which fails to validate the data size during firmware section copying against the allocated buffer size. This allows a local, authenticated attacker to cause a heap overflow.

With a CVSS score of 7.8, this vulnerability represents a high-risk scenario. Exploitation could allow an attacker to escalate privileges or crash the system, resulting in loss of data integrity and availability for business-critical services running on the affected hardware.

Immediate Action: Apply the vendor-provided security updates by upgrading the kernel to version 6.12.103, 6.18.44, 7.1.8, or later.

Proactive Monitoring: Use kernel integrity monitoring tools to detect potential heap corruption or abnormal memory access patterns.

Compensating Controls: Implement strict system access controls to ensure that only authorized personnel can interact with the kernel interface.

Public Exploit Available: No (exploit_available: false)

The risk of local privilege escalation necessitates immediate action. Organizations should schedule and perform kernel updates to the latest stable versions to ensure this memory-handling flaw is corrected.
