CVE-2021-3752 6 Debian, Fedoraproject, Linux and 3 more 27 Debian Linux, Fedora, Linux Kernel and 24 more 2024-11-21 7.9 HIGH 7.1 HIGH
A use-after-free flaw was found in the Linux kernel’s Bluetooth subsystem in the way user calls connect to the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the system or escalate their privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2021-3744 5 Debian, Fedoraproject, Linux and 2 more 24 Debian Linux, Fedora, Linux Kernel and 21 more 2024-11-21 2.1 LOW 5.5 MEDIUM
A memory leak flaw was found in the Linux kernel in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ccp/ccp-ops.c, which allows attackers to cause a denial of service (memory consumption). This vulnerability is similar with the older CVE-2019-18808.
CVE-2021-3743 4 Fedoraproject, Linux, Netapp and 1 more 21 Fedora, Linux Kernel, H300e and 18 more 2024-11-21 3.6 LOW 7.1 HIGH
An out-of-bounds (OOB) memory read flaw was found in the Qualcomm IPC router protocol in the Linux kernel. A missing sanity check 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-2021-3739 3 Fedoraproject, Linux, Netapp 18 Fedora, Linux Kernel, H300e and 15 more 2024-11-21 3.6 LOW 7.1 HIGH
A NULL pointer dereference flaw was found in the btrfs_rm_device function in fs/btrfs/volumes.c in the Linux Kernel, where triggering the bug requires ‘CAP_SYS_ADMIN’. This flaw allows a local attacker to crash the system or leak kernel internal information. The highest threat from this vulnerability is to system availability.
CVE-2021-3736 1 Linux 1 Linux Kernel 2024-11-21 N/A 5.5 MEDIUM
A flaw was found in the Linux kernel. A memory leak problem was found in mbochs_ioctl in samples/vfio-mdev/mbochs.c in Virtual Function I/O (VFIO) Mediated devices. This flaw could allow a local attacker to leak internal kernel information.
CVE-2021-3732 1 Linux 1 Linux Kernel 2024-11-21 2.1 LOW 5.5 MEDIUM
A flaw was found in the Linux kernel's OverlayFS subsystem in the way the user mounts the TmpFS filesystem with OverlayFS. This flaw allows a local user to gain access to hidden files that should not be accessible.
CVE-2021-3718 3 Lenovo, Linux, Microsoft 83 Thinkpad 11e 3rd Gen, Thinkpad 11e 3rd Gen Firmware, Thinkpad 11e 4th Gen Celeron and 80 more 2024-11-21 4.7 MEDIUM 4.3 MEDIUM

CVE-2021-3715 1 Linux 1 Linux Kernel 2024-11-21 7.2 HIGH 7.8 HIGH
A flaw was found in the "Routing decision" classifier in the Linux kernel's Traffic Control networking subsystem in the way it handled changing of classification filters, leading to a use-after-free condition. This flaw allows unprivileged local users to escalate their privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2021-3714 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2024-11-21 N/A 5.9 MEDIUM
A flaw was found in the Linux kernels memory deduplication mechanism. Previous work has shown that memory deduplication can be attacked via a local exploitation mechanism. The same technique can be used if an attacker can upload page sized files and detect the change in access time from a networked service to determine if the page has been merged.
CVE-2021-3679 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2024-11-21 2.1 LOW 5.5 MEDIUM
A lack of CPU resource in the Linux kernel tracing module functionality in versions prior to 5.14-rc3 was found in the way user uses trace ring buffer in a specific way. Only privileged local users (with CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service.
CVE-2021-3669 5 Debian, Fedoraproject, Ibm and 2 more 24 Debian Linux, Fedora, Spectrum Copy Data Management and 21 more 2024-11-21 N/A 5.5 MEDIUM
A flaw was found in the Linux kernel. Measuring usage of the shared memory does not scale with large shared memory segment counts which could lead to resource exhaustion and DoS.
CVE-2021-3659 3 Fedoraproject, Linux, Redhat 17 Fedora, Linux Kernel, Codeready Linux Builder and 14 more 2024-11-21 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-2021-3656 3 Fedoraproject, Linux, Redhat 26 Fedora, Linux Kernel, 3scale Api Management and 23 more 2024-11-21 7.2 HIGH 8.8 HIGH
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virt_ext" field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape.
CVE-2021-3655 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2024-11-21 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-2021-3653 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2024-11-21 6.1 MEDIUM 8.8 HIGH
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "int_ctl" field, this issue could allow a malicious L1 to enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. This flaw affects Linux kernel versions prior to 5.14-rc7.
CVE-2021-3640 5 Canonical, Debian, Fedoraproject and 2 more 20 Ubuntu Linux, Debian Linux, Fedora and 17 more 2024-11-21 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-2021-3635 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2024-11-21 4.9 MEDIUM 4.4 MEDIUM
A flaw was found in the Linux kernel netfilter implementation in versions prior to 5.5-rc7. A user with root (CAP_SYS_ADMIN) access is able to panic the system when issuing netfilter netflow commands.
CVE-2021-3612 6 Debian, Fedoraproject, Linux and 3 more 26 Debian Linux, Fedora, Linux Kernel and 23 more 2024-11-21 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-2021-3609 3 Linux, Netapp, Redhat 43 Linux Kernel, H300e, H300e Firmware and 40 more 2024-11-21 6.9 MEDIUM 7.0 HIGH
.A flaw was found in the CAN BCM networking protocol in the Linux kernel, where a local attacker can abuse a flaw in the CAN subsystem to corrupt memory, crash the system or escalate privileges. This race condition in net/can/bcm.c in the Linux kernel allows for local privilege escalation to root.
CVE-2021-3600 4 Canonical, Fedoraproject, Linux and 1 more 4 Ubuntu Linux, Fedora, Linux Kernel and 1 more 2024-11-21 N/A 7.8 HIGH
It was discovered that the eBPF implementation in the Linux kernel did not properly track bounds information for 32 bit registers when performing div and mod operations. A local attacker could use this to possibly execute arbitrary code.
