The f2fs file system in the linux kernel did not properly validate metadata in some situations.
The fuse user space file system implementation in the linux kernel did not properly handle bad inodes in some situations.
The infiniband rdma userspace connection manager implementation in the linux kernel contained a race condition leading to a use-after-free vulnerability.
The sctp implementation in the linux kernel did not properly perform size validations on incoming packets in some situations.
The qualcomm ipc router protocol implementation in the linux kernel did not properly validate metadata in some situations.
The virtual terminal (vt) device implementation in the linux kernel contained a race condition in its ioctl handling that led to an out-of-bounds read vulnerability.
The linux kernel did not properly account for the memory usage of certain ipc objects.
The nfsv4 client implementation in the linux kernel did not properly order connection setup operations.
The aspeed low pin count (lpc) bus controller implementation in the linux kernel did not properly perform boundary checks in some situations, allowing out-of-bounds write access.

Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

an attacker could use this to construct a malicious f2fs image that, when mounted and operated on, could cause a denial of service (system crash) or possibly execute arbitrary code. (
Cve-2019-19449).
A local attacker could possibly use this to cause a denial of service.
(cve-2020-36322).
A local attacker could use this to cause a denial of service (system crash) or possible execute arbitrary code.

A local attacker could use this to cause a denial of service (memory exhaustion) (cve-2021-3759).
An attacker controlling a remote nfs server could use this to cause a denial of service on the client. (
