| CVE-2021-4149 | 2 Debian, Linux | 2 Debian Linux, Linux Kernel | 2024-11-21 | 5.5 Medium |
| A vulnerability was found in btrfs_alloc_tree_b in fs/btrfs/extent-tree.c in the Linux kernel due to an improper lock operation in btrfs. In this flaw, a user with a local privilege may cause a denial of service (DOS) due to a deadlock problem. | ||||
| CVE-2021-4147 | 3 Fedoraproject, Netapp, Redhat | 3 Fedora, Ontap Select Deploy Administration Utility, Libvirt | 2024-11-21 | 6.5 Medium |
| A flaw was found in the libvirt libxl driver. A malicious guest could continuously reboot itself and cause libvirtd on the host to deadlock or crash, resulting in a denial of service condition. | ||||
| CVE-2021-43429 | 1 Seagate | 1 Cortx-s3 Server | 2024-11-21 | 7.5 High |
| A Denial of Service vulnerability exists in CORTX-S3 Server as of 11/7/2021 via the mempool_destroy method due to a failture to release locks pool->lock. | ||||
| CVE-2021-41213 | 1 Google | 1 Tensorflow | 2024-11-21 | 5.5 Medium |
| TensorFlow is an open source platform for machine learning. In affected versions the code behind `tf.function` API can be made to deadlock when two `tf.function` decorated Python functions are mutually recursive. This occurs due to using a non-reentrant `Lock` Python object. Loading any model which contains mutually recursive functions is vulnerable. An attacker can cause denial of service by causing users to load such models and calling a recursive `tf.function`, although this is not a frequent scenario. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow 2.4.4, as these are also affected and still in supported range. | ||||
| CVE-2021-41141 | 2 Debian, Teluu | 2 Debian Linux, Pjsip | 2024-11-21 | 5.9 Medium |
| PJSIP is a free and open source multimedia communication library written in the C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In various parts of PJSIP, when error/failure occurs, it is found that the function returns without releasing the currently held locks. This could result in a system deadlock, which cause a denial of service for the users. No release has yet been made which contains the linked fix commit. All versions up to an including 2.11.1 are affected. Users may need to manually apply the patch. | ||||

| CVE-2021-38203 | 2 Linux, Netapp | 7 Linux Kernel, Element Software, Hci Bootstrap Os and 4 more | 2024-11-21 | 5.5 Medium |
| btrfs in the Linux kernel before 5.13.4 allows attackers to cause a denial of service (deadlock) via processes that trigger allocation of new system chunks during times when there is a shortage of free space in the system space_info. | ||||
| CVE-2021-31786 | 1 Actions-semi | 10 Ats2815, Ats2815 Firmware, Ats2819 and 7 more | 2024-11-21 | 6.5 Medium |
| The Bluetooth Classic Audio implementation on Actions ATS2815 and ATS2819 devices does not properly handle a connection attempt from a host with the same BDAddress as the current connected BT host, allowing attackers to trigger a disconnection and deadlock of the device by connecting with a forged BDAddress that matches the original connected host. | ||||
| CVE-2021-31785 | 1 Actions-semi | 10 Ats2815, Ats2815 Firmware, Ats2819 and 7 more | 2024-11-21 | 6.5 Medium |
| The Bluetooth Classic implementation on Actions ATS2815 and ATS2819 chipsets does not properly handle the reception of multiple LMP_host_connection_req packets, allowing attackers in radio range to trigger a denial of service (deadlock) of the device via crafted LMP packets. Manual user intervention is required to restart the device and restore Bluetooth communication. | ||||
| CVE-2021-31611 | 1 Zh-jieli | 10 Ac6901, Ac6901 Firmware, Ac6921 and 7 more | 2024-11-21 | 5.7 Medium |
| The Bluetooth Classic implementation on Zhuhai Jieli AC690X and AC692X devices does not properly handle an out-of-order LMP Setup procedure that is followed by a malformed LMP packet, allowing attackers in radio range to deadlock a device via a crafted LMP packet. The user needs to manually reboot the device to restore communication. | ||||
| CVE-2021-31427 | 1 Parallels | 1 Parallels Desktop | 2024-11-21 | 5.6 Medium |
| This vulnerability allows local attackers to disclose sensitive information on affected installations of Parallels Desktop 15.1.5-47309. An attacker must first obtain the ability to execute low-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the Open Tools Gate component. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges and execute arbitrary code in the context of the hypervisor. Was ZDI-CAN-13082. | ||||
| CVE-2021-31422 | 1 Parallels | 1 Parallels Desktop | 2024-11-21 | 7.5 High |
| This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop 16.1.1-49141. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the e1000e virtual device. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the hypervisor. Was ZDI-CAN-12527. | ||||
| CVE-2021-29650 | 4 Debian, Fedoraproject, Linux and 1 more | 5 Debian Linux, Fedora, Linux Kernel and 2 more | 2024-11-21 | 5.5 Medium |
| An issue was discovered in the Linux kernel before 5.11.11. The netfilter subsystem allows attackers to cause a denial of service (panic) because net/netfilter/x_tables.c and include/linux/netfilter/x_tables.h lack a full memory barrier upon the assignment of a new table value, aka CID-175e476b8cdf. | ||||
| CVE-2021-29509 | 3 Debian, Puma, Redhat | 3 Debian Linux, Puma, Satellite | 2024-11-21 | 7.5 High |
| Puma is a concurrent HTTP 1.1 server for Ruby/Rack applications. The fix for CVE-2019-16770 was incomplete. The original fix only protected existing connections that had already been accepted from having their requests starved by greedy persistent-connections saturating all threads in the same process. However, new connections may still be starved by greedy persistent-connections saturating all threads in all processes in the cluster. A `puma` server which received more concurrent `keep-alive` connections than the server had threads in its threadpool would service only a subset of connections, denying service to the unserved connections. This problem has been fixed in `puma` 4.3.8 and 5.3.1. Setting `queue_requests false` also fixes the issue. This is not advised when using `puma` without a reverse proxy, such as `nginx` or `apache`, because you will open yourself to slow client attacks (e.g. slowloris). The fix is very small and a git patch is available for those using unsupported versions of Puma. | ||||
| CVE-2021-28964 | 4 Debian, Fedoraproject, Linux and 1 more | 9 Debian Linux, Fedora, Linux Kernel and 6 more | 2024-11-21 | 4.7 Medium |
| A race condition was discovered in get_old_root in fs/btrfs/ctree.c in the Linux kernel through 5.11.8. It allows attackers to cause a denial of service (BUG) because of a lack of locking on an extent buffer before a cloning operation, aka CID-dbcc7d57bffc. | ||||
| CVE-2021-28951 | 3 Fedoraproject, Linux, Netapp | 11 Fedora, Linux Kernel, A250 and 8 more | 2024-11-21 | 5.5 Medium |
| An issue was discovered in fs/io_uring.c in the Linux kernel through 5.11.8. It allows attackers to cause a denial of service (deadlock) because exit may be waiting to park a SQPOLL thread, but concurrently that SQPOLL thread is waiting for a signal to start, aka CID-3ebba796fa25. | ||||
