CVE-2023-4132 4 Debian, Fedoraproject, Linux and 1 more 6 Debian Linux, Fedora, Linux Kernel and 3 more 2026-06-17 N/A 5.5 MEDIUM
A use-after-free vulnerability was found in the siano smsusb module in the Linux kernel. The bug occurs during device initialization when the siano device is plugged in. This flaw allows a local user to crash the system, causing a denial of service condition.
CVE-2023-4091 3 Fedoraproject, Redhat, Samba 5 Fedora, Enterprise Linux, Enterprise Linux Eus and 2 more 2026-06-17 N/A 6.5 MEDIUM
A vulnerability was discovered in Samba, where the flaw allows SMB clients to truncate files, even with read-only permissions when the Samba VFS module "acl_xattr" is configured with "acl_xattr:ignore system acls = yes". The SMB protocol allows opening files when the client requests read-only access but then implicitly truncates the opened file to 0 bytes if the client specifies a separate OVERWRITE create disposition request. The issue arises in configurations that bypass kernel file system permissions checks, relying solely on Samba's permissions.
CVE-2023-4073 4 Apple, Debian, Fedoraproject and 1 more 4 Macos, Debian Linux, Fedora and 1 more 2026-06-17 N/A 8.8 HIGH
Out of bounds memory access in ANGLE in Google Chrome on Mac prior to 115.0.5790.170 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)
CVE-2023-4001 3 Fedoraproject, Gnu, Redhat 3 Fedora, Grub2, Enterprise Linux 2026-06-17 N/A 6.8 MEDIUM
An authentication bypass flaw was found in GRUB due to the way that GRUB uses the UUID of a device to search for the configuration file that contains the password hash for the GRUB password protection feature. An attacker capable of attaching an external drive such as a USB stick containing a file system with a duplicate UUID (the same as in the "/boot/" file system) can bypass the GRUB password protection feature on UEFI systems, which enumerate removable drives before non-removable ones. This issue was introduced in a downstream patch in Red Hat's version of grub2 and does not affect the upstream package.
CVE-2023-49528 2 Fedoraproject, Ffmpeg 2 Fedora, Ffmpeg 2026-06-17 N/A 8.0 HIGH
Buffer Overflow vulnerability in FFmpeg version n6.1-3-g466799d4f5, allows a local attacker to execute arbitrary code and cause a denial of service (DoS) via the af_dialoguenhance.c:261:5 in the de_stereo component.
CVE-2023-49502 2 Fedoraproject, Ffmpeg 2 Fedora, Ffmpeg 2026-06-17 N/A 8.8 HIGH
Buffer Overflow vulnerability in Ffmpeg v.n6.1-3-g466799d4f5 allows a local attacker to execute arbitrary code via the ff_bwdif_filter_intra_c function in the libavfilter/bwdifdsp.c:125:5 component.
CVE-2023-49501 2 Fedoraproject, Ffmpeg 2 Fedora, Ffmpeg 2026-06-17 N/A 8.0 HIGH
Buffer Overflow vulnerability in Ffmpeg v.n6.1-3-g466799d4f5 allows a local attacker to execute arbitrary code via the config_eq_output function in the libavfilter/asrc_afirsrc.c:495:30 component.
CVE-2023-47272 3 Debian, Fedoraproject, Roundcube 3 Debian Linux, Fedora, Webmail 2026-06-17 N/A 6.1 MEDIUM
Roundcube 1.5.x before 1.5.6 and 1.6.x before 1.6.5 allows XSS via a Content-Type or Content-Disposition header (used for attachment preview or download).
CVE-2023-47212 2 Fedoraproject, Nothings 2 Fedora, Stb Vorbis.c 2026-06-17 N/A 9.8 CRITICAL
A heap-based buffer overflow vulnerability exists in the comment functionality of stb _vorbis.c v1.22. A specially crafted .ogg file can lead to an out-of-bounds write. An attacker can provide a malicious file to trigger this vulnerability.
CVE-2023-47038 3 Fedoraproject, Perl, Redhat 5 Fedora, Perl, Enterprise Linux and 2 more 2026-06-17 N/A 7.0 HIGH
A vulnerability was found in perl 5.30.0 through 5.38.0. This issue occurs when a crafted regular expression is compiled by perl, which can allow an attacker controlled byte buffer overflow in a heap allocated buffer.
CVE-2023-46849 3 Debian, Fedoraproject, Openvpn 4 Debian Linux, Fedora, Openvpn and 1 more 2026-06-17 N/A 7.5 HIGH
Using the --fragment option in certain configuration setups OpenVPN version 2.6.0 to 2.6.6 allows an attacker to trigger a divide by zero behaviour which could cause an application crash, leading to a denial of service.
CVE-2023-46842 2 Fedoraproject, Xen 2 Fedora, Xen 2026-06-17 N/A 6.5 MEDIUM
Unlike 32-bit PV guests, HVM guests may switch freely between 64-bit and other modes. This in particular means that they may set registers used to pass 32-bit-mode hypercall arguments to values outside of the range 32-bit code would be able to set them to. When processing of hypercalls takes a considerable amount of time, the hypervisor may choose to invoke a hypercall continuation. Doing so involves putting (perhaps updated) hypercall arguments in respective registers. For guests not running in 64-bit mode this further involves a certain amount of translation of the values. Unfortunately internal sanity checking of these translated values assumes high halves of registers to always be clear when invoking a hypercall. When this is found not to be the case, it triggers a consistency check in the hypervisor and causes a crash.
CVE-2023-46841 2 Fedoraproject, Xen 2 Fedora, Xen 2026-06-17 N/A 6.5 MEDIUM
Recent x86 CPUs offer functionality named Control-flow Enforcement Technology (CET). A sub-feature of this are Shadow Stacks (CET-SS). CET-SS is a hardware feature designed to protect against Return Oriented Programming attacks. When enabled, traditional stacks holding both data and return addresses are accompanied by so called "shadow stacks", holding little more than return addresses. Shadow stacks aren't writable by normal instructions, and upon function returns their contents are used to check for possible manipulation of a return address coming from the traditional stack. In particular certain memory accesses need intercepting by Xen. In various cases the necessary emulation involves kind of replaying of the instruction. Such replaying typically involves filling and then invoking of a stub. Such a replayed instruction may raise an exceptions, which is expected and dealt with accordingly. Unfortunately the interaction of both of the above wasn't right: Recovery involves removal of a call frame from the (traditional) stack. The counterpart of this operation for the shadow stack was missing.
CVE-2023-46840 2 Fedoraproject, Xen 2 Fedora, Xen 2026-06-17 N/A 4.1 MEDIUM
Incorrect placement of a preprocessor directive in source code results in logic that doesn't operate as intended when support for HVM guests is compiled out of Xen.
CVE-2023-46839 2 Fedoraproject, Xen 2 Fedora, Xen 2026-06-17 N/A 5.3 MEDIUM
PCI devices can make use of a functionality called phantom functions, that when enabled allows the device to generate requests using the IDs of functions that are otherwise unpopulated. This allows a device to extend the number of outstanding requests. Such phantom functions need an IOMMU context setup, but failure to setup the context is not fatal when the device is assigned. Not failing device assignment when such failure happens can lead to the primary device being assigned to a guest, while some of the phantom functions are assigned to a different domain.
CVE-2023-46838 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2026-06-17 N/A 7.5 HIGH
Transmit requests in Xen's virtual network protocol can consist of multiple parts. While not really useful, except for the initial part any of them may be of zero length, i.e. carry no data at all. Besides a certain initial portion of the to be transferred data, these parts are directly translated into what Linux calls SKB fragments. Such converted request parts can, when for a particular SKB they are all of length zero, lead to a de-reference of NULL in core networking code.
CVE-2023-46219 2 Fedoraproject, Haxx 2 Fedora, Curl 2026-06-17 N/A 5.3 MEDIUM
When saving HSTS data to an excessively long file name, curl could end up removing all contents, making subsequent requests using that file unaware of the HSTS status they should otherwise use.
CVE-2023-46218 2 Fedoraproject, Haxx 2 Fedora, Curl 2026-06-17 N/A 6.5 MEDIUM
This flaw allows a malicious HTTP server to set "super cookies" in curl that are then passed back to more origins than what is otherwise allowed or possible. This allows a site to set cookies that then would get sent to different and unrelated sites and domains. It could do this by exploiting a mixed case flaw in curl's function that verifies a given cookie domain against the Public Suffix List (PSL). For example a cookie could be set with `domain=co.UK` when the URL used a lower case hostname `curl.co.uk`, even though `co.uk` is listed as a PSL domain.
CVE-2023-45866 6 Apple, Bluproducts, Canonical and 3 more 16 Ipados, Iphone Os, Iphone Se and 13 more 2026-06-17 N/A 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-2023-45803 2 Fedoraproject, Python 2 Fedora, Urllib3 2026-06-17 N/A 4.2 MEDIUM
urllib3 is a user-friendly HTTP client library for Python. urllib3 previously wouldn't remove the HTTP request body when an HTTP redirect response using status 301, 302, or 303 after the request had its method changed from one that could accept a request body (like `POST`) to `GET` as is required by HTTP RFCs. Although this behavior is not specified in the section for redirects, it can be inferred by piecing together information from different sections and we have observed the behavior in other major HTTP client implementations like curl and web browsers. Because the vulnerability requires a previously trusted service to become compromised in order to have an impact on confidentiality we believe the exploitability of this vulnerability is low. Additionally, many users aren't putting sensitive data in HTTP request bodies, if this is the case then this vulnerability isn't exploitable. Both of the following conditions must be true to be affected by this vulnerability: 1. Using urllib3 and submitting sensitive information in the HTTP request body (such as form data or JSON) and 2. The origin service is compromised and starts redirecting using 301, 302, or 303 to a malicious peer or the redirected-to service becomes compromised. This issue has been addressed in versions 1.26.18 and 2.0.7 and users are advised to update to resolve this issue. Users unable to update should disable redirects for services that aren't expecting to respond with redirects with `redirects=False` and disable automatic redirects with `redirects=False` and handle 301, 302, and 303 redirects manually by stripping the HTTP request body.
