prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the Linux kernel before 5.14.12 allows unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds write.
CVE-2021-41073 4 Debian, Fedoraproject, Linux and 1 more 21 Debian Linux, Fedora, Linux Kernel and 18 more 2023-11-07 7.2 HIGH 7.8 HIGH
loop_rw_iter in fs/io_uring.c in the Linux kernel 5.10 through 5.14.6 allows local users to gain privileges by using IORING_OP_PROVIDE_BUFFERS to trigger a free of a kernel buffer, as demonstrated by using /proc/<pid>/maps for exploitation.
CVE-2021-40490 4 Debian, Fedoraproject, Linux and 1 more 29 Debian Linux, Fedora, Linux Kernel and 26 more 2023-11-07 4.4 MEDIUM 7.0 HIGH

CVE-2021-3923 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2023-11-07 N/A 2.3 LOW
A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a privileged local account can leak kernel stack information when issuing commands to the /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it can be further used to defeat existing kernel protection mechanisms.
CVE-2021-3759 2 Debian, Linux 2 Debian Linux, Linux Kernel 2023-11-07 N/A 5.5 MEDIUM
A memory overflow vulnerability was found in the Linux kernel’s ipc functionality of the memcg subsystem, in the way a user calls the semget function multiple times, creating semaphores. This flaw allows a local user to starve the resources, causing a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2021-3659 3 Fedoraproject, Linux, Redhat 17 Fedora, Linux Kernel, Codeready Linux Builder and 14 more 2023-11-07 N/A 5.5 MEDIUM
A NULL pointer dereference flaw was found in the Linux kernel’s IEEE 802.15.4 wireless networking subsystem in the way the user closes the LR-WPAN connection. This flaw allows a local user to crash the system. The highest threat from this vulnerability is to system availability.
CVE-2021-3640 5 Canonical, Debian, Fedoraproject and 2 more 20 Ubuntu Linux, Debian Linux, Fedora and 17 more 2023-11-07 6.9 MEDIUM 7.0 HIGH
A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del() together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A privileged local user could use this flaw to crash the system or escalate their privileges on the system.
CVE-2021-3612 6 Debian, Fedoraproject, Linux and 3 more 26 Debian Linux, Fedora, Linux Kernel and 23 more 2023-11-07 7.2 HIGH 7.8 HIGH
An out-of-bounds memory write flaw was found in the Linux kernel's joystick devices subsystem in versions before 5.9-rc1, in the way the user calls ioctl JSIOCSBTNMAP. This flaw allows a local user to crash the system or possibly escalate their privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2021-3573 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2023-11-07 6.9 MEDIUM 6.4 MEDIUM
A use-after-free in function hci_sock_bound_ioctl() of the Linux kernel HCI subsystem was found in the way user calls ioct HCIUNBLOCKADDR or other way triggers race condition of the call hci_unregister_dev() together with one of the calls hci_sock_blacklist_add(), hci_sock_blacklist_del(), hci_get_conn_info(), hci_get_auth_info(). A privileged local user could use this flaw to crash the system or escalate their privileges on the system. This flaw affects the Linux kernel versions prior to 5.13-rc5.
CVE-2021-3506 3 Debian, Linux, Netapp 20 Debian Linux, Linux Kernel, Cloud Backup and 17 more 2023-11-07 5.6 MEDIUM 7.1 HIGH
An out-of-bounds (OOB) memory access flaw was found in fs/f2fs/node.c in the f2fs module in the Linux kernel in versions before 5.12.0-rc4. A bounds check failure allows a local attacker to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability.
CVE-2021-3347 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2023-11-07 7.2 HIGH 7.8 HIGH
