CVE-2023-6679 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2026-06-17 N/A 5.5 MEDIUM
A null pointer dereference vulnerability was found in dpll_pin_parent_pin_set() in drivers/dpll/dpll_netlink.c in the Digital Phase Locked Loop (DPLL) subsystem in the Linux kernel. This issue could be exploited to trigger a denial of service.
CVE-2023-6622 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2026-06-17 N/A 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-2023-6610 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-06-17 N/A 7.1 HIGH
An out-of-bounds read vulnerability was found in smb2_dump_detail in fs/smb/client/smb2ops.c in the Linux Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information.
CVE-2023-6606 2 Linux, Redhat 5 Linux Kernel, Enterprise Linux, Enterprise Linux Eus and 2 more 2026-06-17 N/A 7.1 HIGH
An out-of-bounds read vulnerability was found in smbCalcSize in fs/smb/client/netmisc.c in the Linux Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information.
CVE-2023-6563 1 Redhat 6 Enterprise Linux, Keycloak, Openshift Container Platform and 3 more 2026-06-17 N/A 7.7 HIGH
An unconstrained memory consumption vulnerability was discovered in Keycloak. It can be triggered in environments which have millions of offline tokens (> 500,000 users with each having at least 2 saved sessions). If an attacker creates two or more user sessions and then open the "consents" tab of the admin User Interface, the UI attempts to load a huge number of offline client sessions leading to excessive memory and CPU consumption which could potentially crash the entire system.
CVE-2023-6546 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2026-06-17 N/A 7.0 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-2023-6536 3 Debian, Linux, Redhat 17 Debian Linux, Linux Kernel, Codeready Linux Builder Eus and 14 more 2026-06-17 N/A 6.5 MEDIUM
A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver, causing kernel panic and a denial of service.
CVE-2023-6535 2 Linux, Redhat 16 Linux Kernel, Codeready Linux Builder Eus, Codeready Linux Builder Eus For Power Little Endian Eus and 13 more 2026-06-17 N/A 6.5 MEDIUM
A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver, causing kernel panic and a denial of service.
CVE-2023-6531 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-06-17 N/A 7.0 HIGH
A use-after-free flaw was found in the Linux Kernel due to a race problem in the unix garbage collector's deletion of SKB races with unix_stream_read_generic() on the socket that the SKB is queued on.
CVE-2023-6476 1 Redhat 2 Enterprise Linux, Openshift Container Platform 2026-06-17 N/A 6.5 MEDIUM
A flaw was found in CRI-O that involves an experimental annotation leading to a container being unconfined. This may allow a pod to specify and get any amount of memory/cpu, circumventing the kubernetes scheduler and potentially resulting in a denial of service in the node.
CVE-2023-6394 2 Quarkus, Redhat 2 Quarkus, Build Of Quarkus 2026-06-17 N/A 7.4 HIGH
A flaw was found in Quarkus. This issue occurs when receiving a request over websocket with no role-based permission specified on the GraphQL operation, Quarkus processes the request without authentication despite the endpoint being secured. This can allow an attacker to access information and functionality outside of normal granted API permissions.
CVE-2023-6356 3 Debian, Linux, Redhat 17 Debian Linux, Linux Kernel, Codeready Linux Builder Eus and 14 more 2026-06-17 N/A 6.5 MEDIUM
A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver and causing kernel panic and a denial of service.
CVE-2023-6291 1 Redhat 8 Enterprise Linux, Keycloak, Migration Toolkit For Applications and 5 more 2026-06-17 N/A 7.1 HIGH
A flaw was found in the redirect_uri validation logic in Keycloak. This issue may allow a bypass of otherwise explicitly allowed hosts. A successful attack may lead to an access token being stolen, making it possible for the attacker to impersonate other users.
CVE-2023-6277 3 Fedoraproject, Libtiff, Redhat 3 Fedora, Libtiff, Enterprise Linux 2026-06-17 N/A 6.5 MEDIUM
An out-of-memory flaw was found in libtiff. Passing a crafted tiff file to TIFFOpen() API may allow a remote attacker to cause a denial of service via a craft input with size smaller than 379 KB.
CVE-2023-6240 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-06-17 N/A 6.5 MEDIUM
A Marvin vulnerability side-channel leakage was found in the RSA decryption operation in the Linux Kernel. This issue may allow a network attacker to decrypt ciphertexts or forge signatures, limiting the services that use that private key.
CVE-2023-6228 2 Libtiff, Redhat 2 Libtiff, Enterprise Linux 2026-06-17 N/A 3.3 LOW
An issue was found in the tiffcp utility distributed by the libtiff package where a crafted TIFF file on processing may cause a heap-based buffer overflow leads to an application crash.
CVE-2023-6176 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-06-17 N/A 4.7 MEDIUM
A null pointer dereference flaw was found in the Linux kernel API for the cryptographic algorithm scatterwalk functionality. This issue occurs when a user constructs a malicious packet with specific socket configuration, which could allow a local user to crash the system or escalate their privileges on the system.
CVE-2023-6134 1 Redhat 6 Enterprise Linux, Keycloak, Openshift Container Platform and 3 more 2026-06-17 N/A 4.6 MEDIUM
A flaw was found in Keycloak that prevents certain schemes in redirects, but permits them if a wildcard is appended to the token. This issue could allow an attacker to submit a specially crafted request leading to cross-site scripting (XSS) or further attacks. This flaw is the result of an incomplete fix for CVE-2020-10748.
CVE-2023-6121 1 Redhat 1 Enterprise Linux 2026-06-17 N/A 4.3 MEDIUM
An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This issue may allow a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that results in kmalloc data being printed and potentially leaked to the kernel ring buffer (dmesg).
CVE-2023-6004 3 Fedoraproject, Libssh, Redhat 3 Fedora, Libssh, Enterprise Linux 2026-06-17 N/A 4.8 MEDIUM
A flaw was found in libssh. By utilizing the ProxyCommand or ProxyJump feature, users can exploit unchecked hostname syntax on the client. This issue may allow an attacker to inject malicious code into the command of the features mentioned through the hostname parameter.
