CVE-2022-42334 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-02-04 N/A 6.5 MEDIUM
x86/HVM pinned cache attributes mis-handling T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] To allow cachability control for HVM guests with passed through devices, an interface exists to explicitly override defaults which would otherwise be put in place. While not exposed to the affected guests themselves, the interface specifically exists for domains controlling such guests. This interface may therefore be used by not fully privileged entities, e.g. qemu running deprivileged in Dom0 or qemu running in a so called stub-domain. With this exposure it is an issue that - the number of the such controlled regions was unbounded (CVE-2022-42333), - installation and removal of such regions was not properly serialized (CVE-2022-42334).
CVE-2022-42326 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-02-04 N/A 5.5 MEDIUM
Xenstore: Guests can create arbitrary number of nodes via transactions T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] In case a node has been created in a transaction and it is later deleted in the same transaction, the transaction will be terminated with an error. As this error is encountered only when handling the deleted node at transaction finalization, the transaction will have been performed partially and without updating the accounting information. This will enable a malicious guest to create arbitrary number of nodes.

CVE-2022-42324 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-02-04 N/A 5.5 MEDIUM
Oxenstored 32->31 bit integer truncation issues Integers in Ocaml are 63 or 31 bits of signed precision. The Ocaml Xenbus library takes a C uint32_t out of the ring and casts it directly to an Ocaml integer. In 64-bit Ocaml builds this is fine, but in 32-bit builds, it truncates off the most significant bit, and then creates unsigned/signed confusion in the remainder. This in turn can feed a negative value into logic not expecting a negative value, resulting in unexpected exceptions being thrown. The unexpected exception is not handled suitably, creating a busy-loop trying (and failing) to take the bad packet out of the xenstore ring.
CVE-2022-42323 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-02-04 N/A 5.5 MEDIUM
Xenstore: Cooperating guests can create arbitrary numbers of nodes T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Since the fix of XSA-322 any Xenstore node owned by a removed domain will be modified to be owned by Dom0. This will allow two malicious guests working together to create an arbitrary number of Xenstore nodes. This is possible by domain A letting domain B write into domain A's local Xenstore tree. Domain B can then create many nodes and reboot. The nodes created by domain B will now be owned by Dom0. By repeating this process over and over again an arbitrary number of nodes can be created, as Dom0's number of nodes isn't limited by Xenstore quota.

CVE-2022-42321 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-02-04 N/A 6.5 MEDIUM
Xenstore: Guests can crash xenstored via exhausting the stack Xenstored is using recursion for some Xenstore operations (e.g. for deleting a sub-tree of Xenstore nodes). With sufficiently deep nesting levels this can result in stack exhaustion on xenstored, leading to a crash of xenstored.
CVE-2022-42319 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-02-04 N/A 6.5 MEDIUM
Xenstore: Guests can cause Xenstore to not free temporary memory When working on a request of a guest, xenstored might need to allocate quite large amounts of memory temporarily. This memory is freed only after the request has been finished completely. A request is regarded to be finished only after the guest has read the response message of the request from the ring page. Thus a guest not reading the response can cause xenstored to not free the temporary memory. This can result in memory shortages causing Denial of Service (DoS) of xenstored.
CVE-2022-42310 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-02-04 N/A 5.5 MEDIUM
Xenstore: Guests can create orphaned Xenstore nodes By creating multiple nodes inside a transaction resulting in an error, a malicious guest can create orphaned nodes in the Xenstore data base, as the cleanup after the error will not remove all nodes already created. When the transaction is committed after this situation, nodes without a valid parent can be made permanent in the data base.
CVE-2022-33748 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-02-04 N/A 5.6 MEDIUM
lock order inversion in transitive grant copy handling As part of XSA-226 a missing cleanup call was inserted on an error handling path. While doing so, locking requirements were not paid attention to. As a result two cooperating guests granting each other transitive grants can cause locks to be acquired nested within one another, but in respectively opposite order. With suitable timing between the involved grant copy operations this may result in the locking up of a CPU.
CVE-2022-33746 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-02-04 N/A 6.5 MEDIUM
P2M pool freeing may take excessively long The P2M pool backing second level address translation for guests may be of significant size. Therefore its freeing may take more time than is reasonable without intermediate preemption checks. Such checking for the need to preempt was so far missing.
CVE-2022-29901 5 Debian, Fedoraproject, Intel and 2 more 254 Debian Linux, Fedora, Core I3-6100 and 251 more 2024-02-04 1.9 LOW 6.5 MEDIUM
Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under certain microarchitecture-dependent conditions.
CVE-2022-29900 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
Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions.
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-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-2019-15118 5 Canonical, Debian, Linux and 2 more 12 Ubuntu Linux, Debian Linux, Linux Kernel and 9 more 2024-02-03 4.9 MEDIUM 5.5 MEDIUM
check_input_term in sound/usb/mixer.c in the Linux kernel through 5.2.9 mishandles recursion, leading to kernel stack exhaustion.
