## Overview

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

- `linux_kernel < 5.7.3`
- `debian_linux = 9.0`
- `debian_linux = 10.0`
- `500f_firmware`
- `a250_firmware`
- `h410c_firmware`
- `solidfire_&_hci_management_node`
- `solidfire_&_hci_storage_node`
- `hci_compute_node_bios`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.7.3`
