CVE-2022-0847 7 Fedoraproject, Linux, Netapp and 4 more 39 Fedora, Linux Kernel, H300e and 36 more 2024-01-12 7.2 HIGH 7.8 HIGH
A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system.
CVE-2019-14835 8 Canonical, Debian, Fedoraproject and 5 more 44 Ubuntu Linux, Debian Linux, Fedora and 41 more 2023-12-15 7.2 HIGH 7.8 HIGH
A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host.
CVE-2023-4147 4 Debian, Fedoraproject, Linux and 1 more 8 Debian Linux, Fedora, Linux Kernel and 5 more 2023-11-21 N/A 7.8 HIGH
A use-after-free flaw was found in the Linux kernel’s Netfilter functionality when adding a rule with NFTA_RULE_CHAIN_ID. This flaw allows a local user to crash or escalate their privileges on the system.
CVE-2021-3752 6 Debian, Fedoraproject, Linux and 3 more 27 Debian Linux, Fedora, Linux Kernel and 24 more 2023-11-09 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-2021-3609 3 Linux, Netapp, Redhat 43 Linux Kernel, H300e, H300e Firmware and 40 more 2023-08-11 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-2023-0179 4 Canonical, Fedoraproject, Linux and 1 more 14 Ubuntu Linux, Fedora, Linux Kernel and 11 more 2023-08-11 N/A 7.8 HIGH
A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to the root user via arbitrary code execution.
CVE-2022-0435 4 Fedoraproject, Linux, Ovirt and 1 more 23 Fedora, Linux Kernel, Node and 20 more 2022-06-02 9.0 HIGH 8.8 HIGH
A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed. This flaw allows a remote user to crash the system or possibly escalate their privileges if they have access to the TIPC network.
CVE-2022-0330 3 Fedoraproject, Linux, Redhat 30 Fedora, Linux Kernel, 3scale Api Management and 27 more 2022-05-26 4.6 MEDIUM 7.8 HIGH
A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or escalate their privileges on the system.
CVE-2021-3501 4 Fedoraproject, Linux, Netapp and 1 more 27 Fedora, Linux Kernel, Cloud Backup and 24 more 2022-05-13 3.6 LOW 7.1 HIGH
A flaw was found in the Linux kernel in versions before 5.12. The value of internal.ndata, in the KVM API, is mapped to an array index, which can be updated by a user process at anytime which could lead to an out-of-bounds write. The highest threat from this vulnerability is to data integrity and system availability.
CVE-2019-13272 6 Canonical, Debian, Fedoraproject and 3 more 20 Ubuntu Linux, Debian Linux, Fedora and 17 more 2021-11-28 7.2 HIGH 7.8 HIGH
In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments.
CVE-2019-9506 8 Apple, Blackberry, Canonical and 5 more 274 Iphone Os, Mac Os X, Tvos and 271 more 2021-11-04 4.8 MEDIUM 8.1 HIGH
The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka "KNOB") that can decrypt traffic and inject arbitrary ciphertext without the victim noticing.
CVE-2019-14814 6 Canonical, Debian, Linux and 3 more 50 Ubuntu Linux, Debian Linux, Linux Kernel and 47 more 2021-11-02 7.2 HIGH 7.8 HIGH
There is heap-based buffer overflow in Linux kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code.
CVE-2019-14816 6 Canonical, Debian, Linux and 3 more 51 Ubuntu Linux, Debian Linux, Linux Kernel and 48 more 2021-11-02 7.2 HIGH 7.8 HIGH
There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code.
CVE-2019-14821 8 Canonical, Debian, Fedoraproject and 5 more 38 Ubuntu Linux, Debian Linux, Fedora and 35 more 2021-06-02 7.2 HIGH 8.8 HIGH
An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system.
CVE-2016-3707 3 Linux, Novell, Redhat 4 Linux Kernel-rt, Suse Linux Enterprise Real Time Extension, Enterprise Linux For Real Time and 1 more 2016-11-28 6.8 MEDIUM 8.1 HIGH
The icmp_check_sysrq function in net/ipv4/icmp.c in the kernel.org projects/rt patches for the Linux kernel, as used in the kernel-rt package before 3.10.0-327.22.1 in Red Hat Enterprise Linux for Real Time 7 and other products, allows remote attackers to execute SysRq commands via crafted ICMP Echo Request packets, as demonstrated by a brute-force attack to discover a cookie, or an attack that occurs after reading the local icmp_echo_sysrq file.
