CVE-2020-10768 1 Linux 1 Linux Kernel 2026-06-17 2.1 LOW 5.5 MEDIUM
A flaw was found in the Linux Kernel before 5.8-rc1 in the prctl() function, where it can be used to enable indirect branch speculation after it has been disabled. This call incorrectly reports it as being 'force disabled' when it is not and opens the system to Spectre v2 attacks. The highest threat from this vulnerability is to confidentiality.
CVE-2020-10767 1 Linux 1 Linux Kernel 2026-06-17 1.9 LOW 5.5 MEDIUM
A flaw was found in the Linux kernel before 5.8-rc1 in the implementation of the Enhanced IBPB (Indirect Branch Prediction Barrier). The IBPB mitigation will be disabled when STIBP is not available or when the Enhanced Indirect Branch Restricted Speculation (IBRS) is available. This flaw allows a local attacker to perform a Spectre V2 style attack when this configuration is active. The highest threat from this vulnerability is to confidentiality.
CVE-2020-10766 1 Linux 1 Linux Kernel 2026-06-17 2.1 LOW 5.5 MEDIUM
A logic bug flaw was found in Linux kernel before 5.8-rc1 in the implementation of SSBD. A bug in the logic handling allows an attacker with a local account to disable SSBD protection during a context switch when additional speculative execution mitigations are in place. This issue was introduced when the per task/process conditional STIPB switching was added on top of the existing SSBD switching. The highest threat from this vulnerability is to confidentiality.
CVE-2019-6569 1 Siemens 10 Scalance X-200, Scalance X-200 Firmware, Scalance X-300 and 7 more 2026-06-17 6.4 MEDIUM 9.1 CRITICAL
The monitor barrier of the affected products insufficiently blocks data from being forwarded over the mirror port into the mirrored network. An attacker could use this behavior to transmit malicious packets to systems in the mirrored network, possibly influencing their configuration and runtime behavior.
CVE-2019-5108 5 Canonical, Debian, Linux and 2 more 21 Ubuntu Linux, Debian Linux, Linux Kernel and 18 more 2026-06-17 3.3 LOW 6.5 MEDIUM
An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge Authentication and Association Request packets to trigger this vulnerability.
CVE-2019-5062 1 W1.fi 1 Hostapd 2026-06-17 3.3 LOW 6.5 MEDIUM
An exploitable denial-of-service vulnerability exists in the 802.11w security state handling for hostapd 2.6 connected clients with valid 802.11w sessions. By simulating an incomplete new association, an attacker can trigger a deauthentication against stations using 802.11w, resulting in a denial of service.
CVE-2019-5061 1 W1.fi 1 Hostapd 2026-06-17 3.3 LOW 6.5 MEDIUM
An exploitable denial-of-service vulnerability exists in the hostapd 2.6, where an attacker could trigger AP to send IAPP location updates for stations, before the required authentication process has completed. This could lead to different denial of service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby Aps of the same wireless infrastructure. An attacker can forge Authentication and Association Request packets to trigger this vulnerability.
CVE-2018-12550 1 Eclipse 1 Mosquitto 2026-06-17 6.8 MEDIUM 8.1 HIGH
When Eclipse Mosquitto version 1.0 to 1.5.5 (inclusive) is configured to use an ACL file, and that ACL file is empty, or contains only comments or blank lines, then Mosquitto will treat this as though no ACL file has been defined and use a default allow policy. The new behaviour is to have an empty ACL file mean that all access is denied, which is not a useful configuration but is not unexpected.
