| CVE-2020-36777 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2025-05-04 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: media: dvbdev: Fix memory leak in dvb_media_device_free() dvb_media_device_free() is leaking memory. Free `dvbdev->adapter->conn` before setting it to NULL, as documented in include/media/media-device.h: "The media_entity instance itself must be freed explicitly by the driver if required." | ||||
| CVE-2019-25162 | 2 Linux, Redhat | 3 Linux Kernel, Enterprise Linux, Rhel Eus | 2025-05-04 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: i2c: Fix a potential use after free Free the adap structure only after we are done using it. This patch just moves the put_device() down a bit to avoid the use after free. [wsa: added comment to the code, added Fixes tag] | ||||
| CVE-2019-25160 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2025-05-04 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: netlabel: fix out-of-bounds memory accesses There are two array out-of-bounds memory accesses, one in cipso_v4_map_lvl_valid(), the other in netlbl_bitmap_walk(). Both errors are embarassingly simple, and the fixes are straightforward. As a FYI for anyone backporting this patch to kernels prior to v4.8, you'll want to apply the netlbl_bitmap_walk() patch to cipso_v4_bitmap_walk() as netlbl_bitmap_walk() doesn't exist before Linux v4.8. | ||||

| .NET and Visual Studio Remote Code Execution Vulnerability | ||||
| CVE-2024-3446 | 1 Redhat | 2 Advanced Virtualization, Enterprise Linux | 2025-05-02 | 8.2 High |
| A double free vulnerability was found in QEMU virtio devices (virtio-gpu, virtio-serial-bus, virtio-crypto), where the mem_reentrancy_guard flag insufficiently protects against DMA reentrancy issues. This issue could allow a malicious privileged guest user to crash the QEMU process on the host, resulting in a denial of service or allow arbitrary code execution within the context of the QEMU process on the host. | ||||
| CVE-2024-27280 | 2 Redhat, Ruby-lang | 2 Enterprise Linux, Ruby | 2025-05-02 | 9.8 Critical |
| A buffer-overread issue was discovered in StringIO 3.0.1, as distributed in Ruby 3.0.x through 3.0.6 and 3.1.x through 3.1.4. The ungetbyte and ungetc methods on a StringIO can read past the end of a string, and a subsequent call to StringIO.gets may return the memory value. 3.0.3 is the main fixed version; however, for Ruby 3.0 users, a fixed version is stringio 3.0.1.1, and for Ruby 3.1 users, a fixed version is stringio 3.0.1.2. | ||||
| CVE-2023-28362 | 1 Redhat | 1 Satellite | 2025-05-02 | 4 Medium |
| The redirect_to method in Rails allows provided values to contain characters which are not legal in an HTTP header value. This results in the potential for downstream services which enforce RFC compliance on HTTP response headers to remove the assigned Location header. | ||||
| CVE-2024-7318 | 1 Redhat | 2 Build Keycloak, Build Of Keycloak | 2025-05-02 | 4.8 Medium |
| A vulnerability was found in Keycloak. Expired OTP codes are still usable when using FreeOTP when the OTP token period is set to 30 seconds (default). Instead of expiring and deemed unusable around 30 seconds in, the tokens are valid for an additional 30 seconds totaling 1 minute. A one time passcode that is valid longer than its expiration time increases the attack window for malicious actors to abuse the system and compromise accounts. Additionally, it increases the attack surface because at any given time, two OTPs are valid. | ||||
| CVE-2022-44638 | 4 Debian, Fedoraproject, Pixman and 1 more | 5 Debian Linux, Fedora, Pixman and 2 more | 2025-05-02 | 8.8 High |
| In libpixman in Pixman before 0.42.2, there is an out-of-bounds write (aka heap-based buffer overflow) in rasterize_edges_8 due to an integer overflow in pixman_sample_floor_y. | ||||
| CVE-2022-42919 | 3 Fedoraproject, Python, Redhat | 4 Fedora, Python, Enterprise Linux and 1 more | 2025-05-02 | 7.8 High |
| Python 3.9.x before 3.9.16 and 3.10.x before 3.10.9 on Linux allows local privilege escalation in a non-default configuration. The Python multiprocessing library, when used with the forkserver start method on Linux, allows pickles to be deserialized from any user in the same machine local network namespace, which in many system configurations means any user on the same machine. Pickles can execute arbitrary code. Thus, this allows for local user privilege escalation to the user that any forkserver process is running as. Setting multiprocessing.util.abstract_sockets_supported to False is a workaround. The forkserver start method for multiprocessing is not the default start method. This issue is Linux specific because only Linux supports abstract namespace sockets. CPython before 3.9 does not make use of Linux abstract namespace sockets by default. Support for users manually specifying an abstract namespace socket was added as a bugfix in 3.7.8 and 3.8.3, but users would need to make specific uncommon API calls in order to do that in CPython before 3.9. | ||||
| CVE-2022-40284 | 4 Debian, Fedoraproject, Redhat and 1 more | 9 Debian Linux, Fedora, Advanced Virtualization and 6 more | 2025-05-02 | 7.8 High |
| A buffer overflow was discovered in NTFS-3G before 2022.10.3. Crafted metadata in an NTFS image can cause code execution. A local attacker can exploit this if the ntfs-3g binary is setuid root. A physically proximate attacker can exploit this if NTFS-3G software is configured to execute upon attachment of an external storage device. | ||||
| CVE-2022-37865 | 2 Apache, Redhat | 2 Ivy, Camel Spring Boot | 2025-05-02 | 9.1 Critical |
| With Apache Ivy 2.4.0 an optional packaging attribute has been introduced that allows artifacts to be unpacked on the fly if they used pack200 or zip packaging. For artifacts using the "zip", "jar" or "war" packaging Ivy prior to 2.5.1 doesn't verify the target path when extracting the archive. An archive containing absolute paths or paths that try to traverse "upwards" using ".." sequences can then write files to any location on the local fie system that the user executing Ivy has write access to. Ivy users of version 2.4.0 to 2.5.0 should upgrade to Ivy 2.5.1. | ||||
| CVE-2022-3675 | 1 Redhat | 1 Fedora Coreos | 2025-05-02 | 2.6 Low |
| Fedora CoreOS supports setting a GRUB bootloader password using a Butane config. When this feature is enabled, GRUB requires a password to access the GRUB command-line, modify kernel command-line arguments, or boot non-default OSTree deployments. Recent Fedora CoreOS releases have a misconfiguration which allows booting non-default OSTree deployments without entering a password. This allows someone with access to the GRUB menu to boot into an older version of Fedora CoreOS, reverting any security fixes that have recently been applied to the machine. A password is still required to modify kernel command-line arguments and to access the GRUB command line. | ||||
| CVE-2022-3821 | 3 Fedoraproject, Redhat, Systemd Project | 4 Fedora, Enterprise Linux, Rhel Eus and 1 more | 2025-05-02 | 5.5 Medium |
| An off-by-one Error issue was discovered in Systemd in format_timespan() function of time-util.c. An attacker could supply specific values for time and accuracy that leads to buffer overrun in format_timespan(), leading to a Denial of Service. | ||||
| CVE-2024-8883 | 1 Redhat | 10 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform and 7 more | 2025-05-02 | 6.1 Medium |
| A misconfiguration flaw was found in Keycloak. This issue can allow an attacker to redirect users to an arbitrary URL if a 'Valid Redirect URI' is set to http://localhost or http://127.0.0.1, enabling sensitive information such as authorization codes to be exposed to the attacker, potentially leading to session hijacking. | ||||
