CVE-2023-39189 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2025-11-06 5.1 Medium
A flaw was found in the Netfilter subsystem in the Linux kernel. The nfnl_osf_add_callback function did not validate the user mode controlled opt_num field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, leading to a crash or information disclosure.
CVE-2023-6622 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2025-11-06 5.5 Medium
A null pointer dereference vulnerability was found in nft_dynset_init() in net/netfilter/nft_dynset.c in nf_tables in the Linux kernel. This issue may allow a local attacker with CAP_NET_ADMIN user privilege to trigger a denial of service.
CVE-2023-4133 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2025-11-06 5.5 Medium
A use-after-free vulnerability was found in the cxgb4 driver in the Linux kernel. The bug occurs when the cxgb4 device is detaching due to a possible rearming of the flower_stats_timer from the work queue. This flaw allows a local user to crash the system, causing a denial of service condition.
CVE-2023-6546 3 Fedoraproject, Linux, Redhat 9 Fedora, Linux Kernel, Enterprise Linux and 6 more 2025-11-06 7 High
A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This could allow a local unprivileged user to escalate their privileges on the system.
CVE-2019-13272 6 Canonical, Debian, Fedoraproject and 3 more 25 Ubuntu Linux, Debian Linux, Fedora and 22 more 2025-11-06 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-2022-0847 7 Fedoraproject, Linux, Netapp and 4 more 42 Fedora, Linux Kernel, H300e and 39 more 2025-11-06 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-2023-41993 7 Apple, Debian, Fedoraproject and 4 more 17 Ipad Os, Ipados, Iphone Os and 14 more 2025-11-05 8.8 High
The issue was addressed with improved checks. This issue is fixed in macOS Sonoma 14. Processing web content may lead to arbitrary code execution. Apple is aware of a report that this issue may have been actively exploited against versions of iOS before iOS 16.7.
CVE-2024-34397 5 Debian, Fedoraproject, Gnome and 2 more 6 Debian Linux, Fedora, Glib and 3 more 2025-11-04 5.2 Medium
An issue was discovered in GNOME GLib before 2.78.5, and 2.79.x and 2.80.x before 2.80.1. When a GDBus-based client subscribes to signals from a trusted system service such as NetworkManager on a shared computer, other users of the same computer can send spoofed D-Bus signals that the GDBus-based client will wrongly interpret as having been sent by the trusted system service. This could lead to the GDBus-based client behaving incorrectly, with an application-dependent impact.
CVE-2024-28757 4 Fedoraproject, Libexpat Project, Netapp and 1 more 23 Fedora, Libexpat, Active Iq Unified Manager and 20 more 2025-11-04 7.5 High
libexpat through 2.6.1 allows an XML Entity Expansion attack when there is isolated use of external parsers (created via XML_ExternalEntityParserCreate).
CVE-2024-27316 4 Apache, Fedoraproject, Netapp and 1 more 7 Http Server, Fedora, Ontap and 4 more 2025-11-04 7.5 High
HTTP/2 incoming headers exceeding the limit are temporarily buffered in nghttp2 in order to generate an informative HTTP 413 response. If a client does not stop sending headers, this leads to memory exhaustion.
CVE-2023-51764 3 Fedoraproject, Postfix, Redhat 3 Fedora, Postfix, Enterprise Linux 2025-11-04 5.3 Medium
Postfix through 3.8.5 allows SMTP smuggling unless configured with smtpd_data_restrictions=reject_unauth_pipelining and smtpd_discard_ehlo_keywords=chunking (or certain other options that exist in recent versions). Remote attackers can use a published exploitation technique to inject e-mail messages with a spoofed MAIL FROM address, allowing bypass of an SPF protection mechanism. This occurs because Postfix supports <LF>.<CR><LF> but some other popular e-mail servers do not. To prevent attack variants (by always disallowing <LF> without <CR>), a different solution is required, such as the smtpd_forbid_bare_newline=yes option with a Postfix minimum version of 3.5.23, 3.6.13, 3.7.9, 3.8.4, or 3.9.
CVE-2023-50967 3 Fedoraproject, Latchset, Redhat 3 Fedora, Jose, Enterprise Linux 2025-11-04 7.5 High
latchset jose through version 11 allows attackers to cause a denial of service (CPU consumption) via a large p2c (aka PBES2 Count) value.
CVE-2023-48795 42 9bis, Apache, Apple and 39 more 77 Kitty, Sshd, Sshj and 74 more 2025-11-04 5.9 Medium
The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.

CVE-2023-38709 7 Apache, Apple, Broadcom and 4 more 9 Http Server, Macos, Fabric Operating System and 6 more 2025-11-04 7.3 High
Faulty input validation in the core of Apache allows malicious or exploitable backend/content generators to split HTTP responses. This issue affects Apache HTTP Server: through 2.4.58.
CVE-2023-45866 7 Apple, Bluproducts, Canonical and 4 more 17 Ipados, Iphone Os, Iphone Se and 14 more 2025-11-04 6.3 Medium
Bluetooth HID Hosts in BlueZ may permit an unauthenticated Peripheral role HID Device to initiate and establish an encrypted connection, and accept HID keyboard reports, potentially permitting injection of HID messages when no user interaction has occurred in the Central role to authorize such access. An example affected package is bluez 5.64-0ubuntu1 in Ubuntu 22.04LTS. NOTE: in some cases, a CVE-2020-0556 mitigation would have already addressed this Bluetooth HID Hosts issue.
CVE-2023-39928 4 Debian, Fedoraproject, Redhat and 1 more 5 Debian Linux, Fedora, Enterprise Linux and 2 more 2025-11-04 8.8 High
A use-after-free vulnerability exists in the MediaRecorder API of Webkit WebKitGTK 2.40.5. A specially crafted web page can abuse this vulnerability to cause memory corruption and potentially arbitrary code execution. A user would need to to visit a malicious webpage to trigger this vulnerability.
CVE-2022-3786 4 Fedoraproject, Nodejs, Openssl and 1 more 4 Fedora, Node.js, Openssl and 1 more 2025-11-04 7.5 High
A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed a malicious certificate or for an application to continue certificate verification despite failure to construct a path to a trusted issuer. An attacker can craft a malicious email address in a certificate to overflow an arbitrary number of bytes containing the `.' character (decimal 46) on the stack. This buffer overflow could result in a crash (causing a denial of service). In a TLS client, this can be triggered by connecting to a malicious server. In a TLS server, this can be triggered if the server requests client authentication and a malicious client connects.
CVE-2022-3602 5 Fedoraproject, Netapp, Nodejs and 2 more 5 Fedora, Clustered Data Ontap, Node.js and 2 more 2025-11-04 7.5 High
A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer. An attacker can craft a malicious email address to overflow four attacker-controlled bytes on the stack. This buffer overflow could result in a crash (causing a denial of service) or potentially remote code execution. Many platforms implement stack overflow protections which would mitigate against the risk of remote code execution. The risk may be further mitigated based on stack layout for any given platform/compiler. Pre-announcements of CVE-2022-3602 described this issue as CRITICAL. Further analysis based on some of the mitigating factors described above have led this to be downgraded to HIGH. Users are still encouraged to upgrade to a new version as soon as possible. In a TLS client, this can be triggered by connecting to a malicious server. In a TLS server, this can be triggered if the server requests client authentication and a malicious client connects. Fixed in OpenSSL 3.0.7 (Affected 3.0.0,3.0.1,3.0.2,3.0.3,3.0.4,3.0.5,3.0.6).
CVE-2020-26558 6 Bluetooth, Debian, Fedoraproject and 3 more 35 Bluetooth Core Specification, Debian Linux, Fedora and 32 more 2025-11-04 4.2 Medium
Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 through 5.2 may permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication procedure) by reflection of the public key and the authentication evidence of the initiating device, potentially permitting this attacker to complete authenticated pairing with the responding device using the correct Passkey for the pairing session. The attack methodology determines the Passkey value one bit at a time.
CVE-2020-26555 4 Bluetooth, Fedoraproject, Intel and 1 more 33 Bluetooth Core Specification, Fedora, Ac 3165 and 30 more 2025-11-04 5.4 Medium
Bluetooth legacy BR/EDR PIN code pairing in Bluetooth Core Specification 1.0B through 5.2 may permit an unauthenticated nearby device to spoof the BD_ADDR of the peer device to complete pairing without knowledge of the PIN.
