CVE-2023-31084 4 Debian, Fedoraproject, Linux and 1 more 5 Debian Linux, Fedora, Linux Kernel and 2 more 2026-06-17 N/A 5.5 MEDIUM
An issue was discovered in drivers/media/dvb-core/dvb_frontend.c in the Linux kernel 6.2. There is a blocking operation when a task is in !TASK_RUNNING. In dvb_frontend_get_event, wait_event_interruptible is called; the condition is dvb_frontend_test_event(fepriv,events). In dvb_frontend_test_event, down(&fepriv->sem) is called. However, wait_event_interruptible would put the process to sleep, and down(&fepriv->sem) may block the process.
CVE-2023-0160 2 Fedoraproject, Linux 2 Fedora, Linux Kernel 2026-06-17 N/A 4.7 MEDIUM
A deadlock flaw was found in the Linux kernel’s BPF subsystem. This flaw allows a local user to potentially crash the system.
CVE-2022-4269 1 Linux 1 Linux Kernel 2026-06-17 N/A 5.5 MEDIUM
A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking configuration (redirecting egress packets to ingress using TC action "mirred") a local unprivileged user could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a retransmission, resulting in a denial of service condition.

CVE-2021-1622 1 Cisco 13 7600 Router, Asr 901-12c-f-d, Asr 901-12c-ft-d and 10 more 2026-06-17 4.3 MEDIUM 8.6 HIGH
A vulnerability in the Common Open Policy Service (COPS) of Cisco IOS XE Software for Cisco cBR-8 Converged Broadband Routers could allow an unauthenticated, remote attacker to cause resource exhaustion, resulting in a denial of service (DoS) condition. This vulnerability is due to a deadlock condition in the code when processing COPS packets under certain conditions. An attacker could exploit this vulnerability by sending COPS packets with high burst rates to an affected device. A successful exploit could allow the attacker to cause the CPU to consume excessive resources, which prevents other control plane processes from obtaining resources and results in a DoS.
