CVE-2026-46302

A flaw was found in the Linux kernel's Security-Enhanced Linux SELinux policy handling. A local attacker could exploit this by opening the /sys/fs/selinux/policy file, which prevents other processes from accessing or reading the kernel's security policy. This could lead to a denial of service DoS...

Astra Linux – Vulnerability in libvirt

A flaw was discovered in libvirt during its generation of SELinux MCS category pairs for virtual machines’ dynamic labels. This flaw allows one exploited guest to access files labeled for another guest, resulting in the breach of sVirt confinement. The greatest threat posed by this vulnerability...

Astra Linux – Vulnerability in Zabbix

During Zabbix installation from RPM, the DACOVERRIDE SELinux capability is used to access PID files in the /var/run/zabbix folder. In this case, processes of Zabbix Proxy or Server can bypass the file read, write, and execute permission checks at the file system level...

PT-2026-34497

Name of the Vulnerable Software and Affected Versions uutils coreutils affected versions not specified Description The mknod utility fails to handle security labels atomically because it creates device nodes before setting the SELinux context. If the labeling process fails, the utility attempts...

Unity Linux 20.1070e Security Update: kernel (UTSA-2026-013295)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-013295 advisory. In several functions of binder.c, there is a possible way to represent the wrong domain to SELinux due to a race condition. This could lead to local escalation of...

SUSE-SU-2026:20585-1 Security update for docker-stable

This update for docker-stable fixes the following issues: - Enable SELinux in default daemon.json config --selinux-enabled. This has no practical impact on non-SELinux systems bsc1252290. - Remove git-core recommends on SLE. Most SLE systems have installRecommends=yes by default and thus end up...

runc: opencontainers/selinux: container escape and denial of service due to arbitrary write gadgets and procfs write redirects

A flaw was found in runc. This attack is a more sophisticated variant of CVE-2019-16884, which was a flaw that allowed an attacker to trick runc into writing the LSM process labels for a container process into a dummy tmpfs file and thus not apply the correct LSM labels to the container process...
