Linux kernel buffer overflow vulnerability (CNVD-2021-39045)

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A buffer error vulnerability exists in Linux Kernel version 5.12.7 and prior versions, which stems from an incorrect restriction enforced on pointer arithmetic operations that...

CVE-2021-33200

kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corne...
