In the Linux kernel through 5.15.2, hw_atl_utils_fw_rpc_wait in drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c allows an attacker (who can introduce a crafted device) to trigger an out-of-bounds write via a crafted length value.
CVE-2021-37159 3 Debian, Linux, Oracle 5 Debian Linux, Linux Kernel, Communications Cloud Native Core Binding Support Function and 2 more 2026-10-08 4.4 MEDIUM 6.4 MEDIUM
hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel through 5.13.4 calls unregister_netdev without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free.
CVE-2021-33656 3 Debian, Linux, Openatom 3 Debian Linux, Linux Kernel, Openeuler 2026-10-08 N/A 6.8 MEDIUM
When setting font with malicous data by ioctl cmd PIO_FONT,kernel will write memory out of bounds.
CVE-2020-36558 1 Linux 1 Linux Kernel 2026-10-08 N/A 5.1 MEDIUM
A race condition in the Linux kernel before 5.5.7 involving VT_RESIZEX could lead to a NULL pointer dereference and general protection fault.
CVE-2025-59489 5 Apple, Google, Linux and 2 more 5 Macos, Android, Linux Kernel and 2 more 2026-10-08 N/A 7.4 HIGH
Unity Runtime before 2025-10-02 on Android, Windows, macOS, and Linux allows argument injection that can result in loading of library code from an unintended location. If an application was built with a version of Unity Editor that had the vulnerable Unity Runtime code, then an adversary may be able to execute code on, and exfiltrate confidential information from, the machine on which that application is running. NOTE: product status is provided for Unity Editor because that is the information available from the Supplier. However, updating Unity Editor typically does not address the effects of the vulnerability; instead, it is necessary to rebuild and redeploy all affected applications.
CVE-2023-4459 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-10-08 N/A 5.5 MEDIUM
A NULL pointer dereference flaw was found in vmxnet3_rq_cleanup in drivers/net/vmxnet3/vmxnet3_drv.c in the networking sub-component in vmxnet3 in the Linux Kernel. This issue may allow a local attacker with normal user privilege to cause a denial of service due to a missing sanity check during cleanup.
CVE-2022-0264 1 Linux 1 Linux Kernel 2026-10-08 2.1 LOW 5.5 MEDIUM
A vulnerability was found in the Linux kernel's eBPF verifier when handling internal data structures. Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit mitigations in place for the kernel. This flaws affects kernel versions < v5.16-rc6
CVE-2021-4135 1 Linux 1 Linux Kernel 2026-10-08 N/A 5.5 MEDIUM
A memory leak vulnerability was found in the Linux kernel's eBPF for the Simulated networking device driver in the way user uses BPF for the device such that function nsim_map_alloc_elem being called. A local user could use this flaw to get unauthorized access to some data.
CVE-2021-4001 1 Linux 1 Linux Kernel 2026-10-08 4.7 MEDIUM 4.1 MEDIUM
A race condition was found in the Linux kernel's ebpf verifier between bpf_map_update_elem and bpf_map_freeze due to a missing lock in kernel/bpf/syscall.c. In this flaw, a local user with a special privilege (cap_sys_admin or cap_bpf) can modify the frozen mapped address space. This flaw affects kernel versions prior to 5.16 rc2.
CVE-2021-45402 1 Linux 1 Linux Kernel 2026-10-08 2.1 LOW 5.5 MEDIUM
The check_alu_op() function in kernel/bpf/verifier.c in the Linux kernel through v5.16-rc5 did not properly update bounds while handling the mov32 instruction, which allows local users to obtain potentially sensitive address information, aka a "pointer leak."
CVE-2021-3655 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2026-10-08 2.1 LOW 3.3 LOW
A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on inbound SCTP packets may allow the kernel to read uninitialized memory.
CVE-2021-38206 1 Linux 1 Linux Kernel 2026-10-08 2.1 LOW 5.5 MEDIUM
The mac80211 subsystem in the Linux kernel before 5.12.13, when a device supporting only 5 GHz is used, allows attackers to cause a denial of service (NULL pointer dereference in the radiotap parser) by injecting a frame with 802.11a rates.
CVE-2021-38199 3 Debian, Linux, Netapp 8 Debian Linux, Linux Kernel, Element Software and 5 more 2026-10-08 3.3 LOW 6.5 MEDIUM
fs/nfs/nfs4client.c in the Linux kernel before 5.13.4 has incorrect connection-setup ordering, which allows operators of remote NFSv4 servers to cause a denial of service (hanging of mounts) by arranging for those servers to be unreachable during trunking detection.
CVE-2021-38198 2 Debian, Linux 2 Debian Linux, Linux Kernel 2026-10-08 2.1 LOW 5.5 MEDIUM
arch/x86/kvm/mmu/paging_tmpl.h in the Linux kernel before 5.12.11 incorrectly computes the access permissions of a shadow page, leading to a missing guest protection page fault.
CVE-2021-38166 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2026-10-08 4.6 MEDIUM 7.8 HIGH
In kernel/bpf/hashtab.c in the Linux kernel through 5.13.8, there is an integer overflow and out-of-bounds write when many elements are placed in a single bucket. NOTE: exploitation might be impractical without the CAP_SYS_ADMIN capability.
CVE-2021-35477 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2026-10-08 2.1 LOW 5.5 MEDIUM
In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store operation does not necessarily occur before a store operation that has an attacker-controlled value.
CVE-2021-34866 2 Linux, Netapp 17 Linux Kernel, H300e, H300e Firmware and 14 more 2026-10-08 7.2 HIGH 7.8 HIGH
This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel 5.14-rc3. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of eBPF programs. The issue results from the lack of proper validation of user-supplied eBPF programs, which can result in a type confusion condition. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel. Was ZDI-CAN-14689.
CVE-2021-34693 2 Debian, Linux 2 Debian Linux, Linux Kernel 2026-10-08 2.1 LOW 5.5 MEDIUM
net/can/bcm.c in the Linux kernel through 5.12.10 allows local users to obtain sensitive information from kernel stack memory because parts of a data structure are uninitialized.
CVE-2021-34556 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2026-10-08 2.1 LOW 5.5 MEDIUM
In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects the possibility of uninitialized memory locations on the BPF stack.
CVE-2021-33624 2 Debian, Linux 2 Debian Linux, Linux Kernel 2026-10-08 4.7 MEDIUM 4.7 MEDIUM
In kernel/bpf/verifier.c in the Linux kernel before 5.12.13, a branch can be mispredicted (e.g., because of type confusion) and consequently an unprivileged BPF program can read arbitrary memory locations via a side-channel attack, aka CID-9183671af6db.
