Description
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 configurations
• linux linux kernel (< 5.7.3)
• debian debian linux 9.0
• debian debian linux 10.0
• netapp 500f firmware
• netapp a250 firmware
• netapp h410c firmware
• netapp solidfire \& hci management node
• netapp solidfire \& hci storage node
• netapp hci compute node bios
