Lifecycle Timeline
1DescriptionNVD
An issue was discovered in the Linux kernel before 5.7.3, related to mm/gup.c and mm/huge_memory.c. The get_user_pages (aka gup) implementation, when used for a copy-on-write page, does not properly consider the semantics of read operations and therefore can grant unintended write access, aka CID-17839856fd58.
AnalysisAI
An issue was discovered in the Linux kernel before 5.7.3, related to mm/gup.c and mm/huge_memory.c. Rated low severity (CVSS 3.6). Public exploit code available.
Technical ContextAI
This vulnerability is classified under CWE-362. An issue was discovered in the Linux kernel before 5.7.3, related to mm/gup.c and mm/huge_memory.c. The get_user_pages (aka gup) implementation, when used for a copy-on-write page, does not properly consider the semantics of read operations and therefore can grant unintended write access, aka CID-17839856fd58. Affected products include: Linux Linux Kernel, Debian Debian Linux, Netapp 500F Firmware, Netapp A250 Firmware, Netapp H410C Firmware. Version information: before 5.7.3.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Apply vendor patches when available. Implement network segmentation and monitoring as interim mitigations.
