CVE-2022-26361 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-02-04 4.4 MEDIUM 7.8 HIGH
IOMMU: RMRR (VT-d) and unity map (AMD-Vi) handling issues T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Certain PCI devices in a system might be assigned Reserved Memory Regions (specified via Reserved Memory Region Reporting, "RMRR") for Intel VT-d or Unity Mapping ranges for AMD-Vi. These are typically used for platform tasks such as legacy USB emulation. Since the precise purpose of these regions is unknown, once a device associated with such a region is active, the mappings of these regions need to remain continuouly accessible by the device. This requirement has been violated. Subsequent DMA or interrupts from the device may have unpredictable behaviour, ranging from IOMMU faults to memory corruption.
CVE-2022-26360 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-02-04 4.4 MEDIUM 7.8 HIGH

CVE-2022-26357 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-02-04 6.2 MEDIUM 7.0 HIGH
race in VT-d domain ID cleanup Xen domain IDs are up to 15 bits wide. VT-d hardware may allow for only less than 15 bits to hold a domain ID associating a physical device with a particular domain. Therefore internally Xen domain IDs are mapped to the smaller value range. The cleaning up of the housekeeping structures has a race, allowing for VT-d domain IDs to be leaked and flushes to be bypassed.
CVE-2022-26356 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-02-04 4.0 MEDIUM 5.6 MEDIUM
Racy interactions between dirty vram tracking and paging log dirty hypercalls Activation of log dirty mode done by XEN_DMOP_track_dirty_vram (was named HVMOP_track_dirty_vram before Xen 4.9) is racy with ongoing log dirty hypercalls. A suitably timed call to XEN_DMOP_track_dirty_vram can enable log dirty while another CPU is still in the process of tearing down the structures related to a previously enabled log dirty mode (XEN_DOMCTL_SHADOW_OP_OFF). This is due to lack of mutually exclusive locking between both operations and can lead to entries being added in already freed slots, resulting in a memory leak.
CVE-2022-23825 4 Amd, Debian, Fedoraproject and 1 more 249 A10-9600p, A10-9600p Firmware, A10-9630p and 246 more 2024-02-04 2.1 LOW 6.5 MEDIUM
Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure.
CVE-2022-23824 3 Amd, Fedoraproject, Xen 336 A10-9600p, A10-9600p Firmware, A10-9630p and 333 more 2024-02-04 N/A 5.5 MEDIUM
IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure.
CVE-2021-28709 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-02-04 6.9 MEDIUM 7.8 HIGH
issues with partially successful P2M updates on x86 T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] x86 HVM and PVH guests may be started in populate-on-demand (PoD) mode, to provide a way for them to later easily have more memory assigned. Guests are permitted to control certain P2M aspects of individual pages via hypercalls. These hypercalls may act on ranges of pages specified via page orders (resulting in a power-of-2 number of pages). In some cases the hypervisor carries out the requests by splitting them into smaller chunks. Error handling in certain PoD cases has been insufficient in that in particular partial success of some operations was not properly accounted for. There are two code paths affected - page removal (CVE-2021-28705) and insertion of new pages (CVE-2021-28709). (We provide one patch which combines the fix to both issues.)
CVE-2021-28708 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-02-04 6.9 MEDIUM 8.8 HIGH
PoD operations on misaligned GFNs T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] x86 HVM and PVH guests may be started in populate-on-demand (PoD) mode, to provide a way for them to later easily have more memory assigned. Guests are permitted to control certain P2M aspects of individual pages via hypercalls. These hypercalls may act on ranges of pages specified via page orders (resulting in a power-of-2 number of pages). The implementation of some of these hypercalls for PoD does not enforce the base page frame number to be suitably aligned for the specified order, yet some code involved in PoD handling actually makes such an assumption. These operations are XENMEM_decrease_reservation (CVE-2021-28704) and XENMEM_populate_physmap (CVE-2021-28707), the latter usable only by domains controlling the guest, i.e. a de-privileged qemu or a stub domain. (Patch 1, combining the fix to both these two issues.) In addition handling of XENMEM_decrease_reservation can also trigger a host crash when the specified page order is neither 4k nor 2M nor 1G (CVE-2021-28708, patch 2).

CVE-2021-28706 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-02-04 7.8 HIGH 8.6 HIGH
guests may exceed their designated memory limit When a guest is permitted to have close to 16TiB of memory, it may be able to issue hypercalls to increase its memory allocation beyond the administrator established limit. This is a result of a calculation done with 32-bit precision, which may overflow. It would then only be the overflowed (and hence small) number which gets compared against the established upper bound.
CVE-2021-28705 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-02-04 6.9 MEDIUM 7.8 HIGH

CVE-2021-38593 2 Fedoraproject, Qt 2 Fedora, Qt 2024-02-03 5.0 MEDIUM 7.5 HIGH
Qt 5.x before 5.15.6 and 6.x through 6.1.2 has an out-of-bounds write in QOutlineMapper::convertPath (called from QRasterPaintEngine::fill and QPaintEngineEx::stroke).
CVE-2020-28049 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2024-02-03 3.3 LOW 6.3 MEDIUM
An issue was discovered in SDDM before 0.19.0. It incorrectly starts the X server in a way that - for a short time period - allows local unprivileged users to create a connection to the X server without providing proper authentication. A local attacker can thus access X server display contents and, for example, intercept keystrokes or access the clipboard. This is caused by a race condition during Xauthority file creation.
CVE-2020-27619 3 Fedoraproject, Oracle, Python 3 Fedora, Communications Cloud Native Core Network Function Cloud Native Environment, Python 2024-02-03 7.5 HIGH 9.8 CRITICAL
In Python 3 through 3.9.0, the Lib/test/multibytecodec_support.py CJK codec tests call eval() on content retrieved via HTTP.
CVE-2023-2156 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2024-02-03 N/A 7.5 HIGH
A flaw was found in the networking subsystem of the Linux kernel within the handling of the RPL protocol. This issue results from the lack of proper handling of user-supplied data, which can lead to an assertion failure. This may allow an unauthenticated remote attacker to create a denial of service condition on the system.
CVE-2022-2621 2 Fedoraproject, Google 2 Fedora, Chrome 2024-02-02 N/A 8.8 HIGH
Use after free in Extensions in Google Chrome prior to 104.0.5112.79 allowed an attacker who convinced a user to install a malicious extension to potentially exploit heap corruption via specific UI interactions.
CVE-2010-1772 5 Canonical, Fedoraproject, Google and 2 more 5 Ubuntu Linux, Fedora, Chrome and 2 more 2024-02-02 6.8 MEDIUM 8.8 HIGH
Use-after-free vulnerability in page/Geolocation.cpp in WebCore in WebKit before r59859, as used in Google Chrome before 5.0.375.70, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted web site, related to failure to stop timers associated with geolocation upon deletion of a document.
