Lifecycle Timeline
1DescriptionNVD
A memory leak flaw was found in the Linux kernel in acrn_dev_ioctl in the drivers/virt/acrn/hsm.c function in how the ACRN Device Model emulates virtual NICs in VM. This flaw allows a local privileged attacker to leak unauthorized kernel information, causing a denial of service.
AnalysisAI
A memory leak flaw was found in the Linux kernel in acrn_dev_ioctl in the drivers/virt/acrn/hsm.c function in how the ACRN Device Model emulates virtual NICs in VM. Rated high severity (CVSS 7.1), this vulnerability is low attack complexity.
Technical ContextAI
This vulnerability is classified as Memory Leak (CWE-401), which allows attackers to exhaust available memory leading to denial of service. A memory leak flaw was found in the Linux kernel in acrn_dev_ioctl in the drivers/virt/acrn/hsm.c function in how the ACRN Device Model emulates virtual NICs in VM. This flaw allows a local privileged attacker to leak unauthorized kernel information, causing a denial of service. Affected products include: Linux Linux Kernel.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Ensure all allocated memory is properly freed. Use RAII patterns or garbage-collected languages.
