CVE-2023-4623 3 Debian, Linux, Redhat 9 Debian Linux, Linux Kernel, Enterprise Linux and 6 more 2025-02-27 7.8 High
A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control) component can be exploited to achieve local privilege escalation. If a class with a link-sharing curve (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing curve, then init_vf() will call vttree_insert() on the parent, but vttree_remove() will be skipped in update_vf(). This leaves a dangling pointer that can cause a use-after-free. We recommend upgrading past commit b3d26c5702c7d6c45456326e56d2ccf3f103e60f.
CVE-2023-4155 3 Fedoraproject, Linux, Redhat 7 Fedora, Linux Kernel, Enterprise Linux and 4 more 2025-02-27 5.3 Medium
A flaw was found in KVM AMD Secure Encrypted Virtualization (SEV) in the Linux kernel. A KVM guest using SEV-ES or SEV-SNP with multiple vCPUs can trigger a double fetch race condition vulnerability and invoke the `VMGEXIT` handler recursively. If an attacker manages to call the handler multiple times, they can trigger a stack overflow and cause a denial of service or potentially guest-to-host escape in kernel configurations without stack guard pages (`CONFIG_VMAP_STACK`).
CVE-2023-2163 2 Linux, Redhat 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more 2025-02-27 10 Critical
Incorrect verifier pruning in BPF in Linux Kernel >=5.4 leads to unsafe code paths being incorrectly marked as safe, resulting in arbitrary read/write in kernel memory, lateral privilege escalation, and container escape.
CVE-2023-42753 3 Debian, Linux, Redhat 9 Debian Linux, Linux Kernel, Enterprise Linux and 6 more 2025-02-27 7 High
An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash the system or potentially escalate their privileges on the system.
CVE-2023-39191 3 Fedoraproject, Linux, Redhat 4 Fedora, Linux Kernel, Enterprise Linux and 1 more 2025-02-27 8.2 High
An improper input validation flaw was found in the eBPF subsystem in the Linux kernel. The issue occurs due to a lack of proper validation of dynamic pointers within user-supplied eBPF programs prior to executing them. This may allow an attacker with CAP_BPF privileges to escalate privileges and execute arbitrary code in the context of the kernel.
CVE-2023-1192 2 Linux, Redhat 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more 2025-02-27 6.5 Medium
A use-after-free flaw was found in smb2_is_status_io_timeout() in CIFS in the Linux Kernel. After CIFS transfers response data to a system call, there are still local variable points to the memory region, and if the system call frees it faster than CIFS uses it, CIFS will access a free memory region, leading to a denial of service.
CVE-2024-26735 1 Redhat 5 Enterprise Linux, Rhel Aus, Rhel E4s and 2 more 2025-02-27 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: fix possible use-after-free and null-ptr-deref The pernet operations structure for the subsystem must be registered before registering the generic netlink family.
CVE-2024-26808 1 Redhat 3 Enterprise Linux, Rhel E4s, Rhel Eus 2025-02-27 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_chain_filter: handle NETDEV_UNREGISTER for inet/ingress basechain Remove netdevice from inet/ingress basechain in case NETDEV_UNREGISTER event is reported, otherwise a stale reference to netdevice remains in the hook list.
CVE-2023-28450 2 Redhat, Thekelleys 3 Enterprise Linux, Rhel Eus, Dnsmasq 2025-02-26 7.5 High
An issue was discovered in Dnsmasq before 2.90. The default maximum EDNS.0 UDP packet size was set to 4096 but should be 1232 because of DNS Flag Day 2020.
CVE-2023-28617 2 Gnu, Redhat 6 Org Mode, Enterprise Linux, Rhel Aus and 3 more 2025-02-26 7.8 High
org-babel-execute:latex in ob-latex.el in Org Mode through 9.6.1 for GNU Emacs allows attackers to execute arbitrary commands via a file name or directory name that contains shell metacharacters.
CVE-2023-38180 3 Fedoraproject, Microsoft, Redhat 7 Fedora, .net, Asp.net Core and 4 more 2025-02-26 7.5 High
.NET and Visual Studio Denial of Service Vulnerability
CVE-2023-0386 2 Linux, Redhat 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more 2025-02-26 7.8 High
A flaw was found in the Linux kernel, where unauthorized access to the execution of the setuid file with capabilities was found in the Linux kernel’s OverlayFS subsystem in how a user copies a capable file from a nosuid mount into another mount. This uid mapping bug allows a local user to escalate their privileges on the system.
CVE-2024-25111 4 Fedoraproject, Netapp, Redhat and 1 more 8 Fedora, Bluexp, Enterprise Linux and 5 more 2025-02-26 8.6 High
Squid is a web proxy cache. Starting in version 3.5.27 and prior to version 6.8, Squid may be vulnerable to a Denial of Service attack against HTTP Chunked decoder due to an uncontrolled recursion bug. This problem allows a remote attacker to cause Denial of Service when sending a crafted, chunked, encoded HTTP Message. This bug is fixed in Squid version 6.8. In addition, patches addressing this problem for the stable releases can be found in Squid's patch archives. There is no workaround for this issue.
CVE-2024-11614 1 Redhat 6 Enterprise Linux, Openshift, Rhel Aus and 3 more 2025-02-26 N/A
An out-of-bounds read vulnerability was found in DPDK's Vhost library checksum offload feature. This issue enables an untrusted or compromised guest to crash the hypervisor's vSwitch by forging Virtio descriptors to cause out-of-bounds reads. This flaw allows an attacker with a malicious VM using a virtio driver to cause the vhost-user side to crash by sending a packet with a Tx checksum offload request and an invalid csum_start offset.
CVE-2023-0056 3 Fedoraproject, Haproxy, Redhat 12 Extra Packages For Enterprise Linux, Fedora, Haproxy and 9 more 2025-02-25 6.5 Medium
An uncontrolled resource consumption vulnerability was discovered in HAProxy which could crash the service. This issue could allow an authenticated remote attacker to run a specially crafted malicious server in an OpenShift cluster. The biggest impact is to availability.
CVE-2024-2614 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Firefox Esr and 6 more 2025-02-25 8.8 High
Memory safety bugs present in Firefox 123, Firefox ESR 115.8, and Thunderbird 115.8. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird < 115.9.
CVE-2024-2616 2 Mozilla, Redhat 7 Firefox, Thunderbird, Enterprise Linux and 4 more 2025-02-25 2.7 Low
To harden ICU against exploitation, the behavior for out-of-memory conditions was changed to crash instead of attempt to continue. This vulnerability affects Firefox ESR < 115.9 and Thunderbird < 115.9.
CVE-2024-52337 1 Redhat 9 Enterprise Linux, Rhel Aus, Rhel E4s and 6 more 2025-02-25 5.5 Medium
A log spoofing flaw was found in the Tuned package due to improper sanitization of some API arguments. This flaw allows an attacker to pass a controlled sequence of characters; newlines can be inserted into the log. Instead of the 'evil' the attacker could mimic a valid TuneD log line and trick the administrator. The quotes '' are usually used in TuneD logs citing raw user input, so there will always be the ' character ending the spoofed input, and the administrator can easily overlook this. This logged string is later used in logging and in the output of utilities, for example, `tuned-adm get_instances` or other third-party programs that use Tuned's D-Bus interface for such operations.
CVE-2023-0494 3 Fedoraproject, Redhat, X.org 22 Fedora, Enterprise Linux, Enterprise Linux Aus and 19 more 2025-02-24 7.8 High
A vulnerability was found in X.Org. This issue occurs due to a dangling pointer in DeepCopyPointerClasses that can be exploited by ProcXkbSetDeviceInfo() and ProcXkbGetDeviceInfo() to read and write into freed memory. This can lead to local privilege elevation on systems where the X server runs privileged and remote code execution for ssh X forwarding sessions.
CVE-2023-1075 2 Linux, Redhat 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more 2025-02-24 3.3 Low
A flaw was found in the Linux Kernel. The tls_is_tx_ready() incorrectly checks for list emptiness, potentially accessing a type confused entry to the list_head, leaking the last byte of the confused field that overlaps with rec->tx_ready.
