SUSE CVE-2021-43816
containerd is an open source container runtime. On installations using SELinux, such as EL8 CentOS, RHEL, Fedora, or SUSE MicroOS, with containerd since v1.5.0-beta.0 as the backing container runtime interface CRI, an unprivileged pod scheduled to the node may bind mount, via hostPath volume, any...
SUSE CVE-2022-23132
During Zabbix installation from RPM, DACOVERRIDE SELinux capability is in use to access PID files in /var/run/zabbix folder. In this case, Zabbix Proxy or Server processes can bypass file read, write and execute permissions check on the file system level...

An issue was discovered in the Linux kernel before 5.14.8. A use-after-free in selinux_ptrace_traceme (aka the SELinux handler for PTRACE_TRACEME) could be used by local attackers to cause memory corruption and escalate privileges aka CID-a3727a8bac0a. This occurs because of an attempt to access the subjective credentials of another task.

CVE-2021-0691
In the SELinux policy configured in systemapp.te, there is a possible way for systemapp to gain code execution in other processes due to an overly-permissive SELinux policy. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed fo...
The vulnerability of the __cil_verify_classperms() function in the SELinux access control system allows a perpetrator to trigger a service failure.
The vulnerability of the cilverifyclassperms function in the SELinux access control system is related to the use of memory after it is freed. Exploiting this vulnerability could allow an attacker to trigger a service failure...
The vulnerability of the cil_reset_classpermission() function in the SELinux access control system allows a perpetrator to trigger a service failure.

UBUNTU-CVE-2021-36087
The CIL compiler in SELinux 3.2 has a heap-based buffer over-read in ebitmapmatchany called indirectly from cilcheckneverallow. This occurs because there is sometimes a lack of checks for invalid statements in an optional block...
SELinux 资源管理错误漏洞
SELinux is a Linux subsystem from the National Security Agency that uses a secure architecture that allows administrators to better control who has access to the system. A security vulnerability exists in SELinux version 3.2, which stems from a use-after-free in the SELinux CIL compiler in the...

sudo: symbolic link attack in SELinux-enabled sudoedit
A race condition vulnerability was found in the temporary file handling of sudoedit's SELinux RBAC support. On systems where SELinux is enabled, this flaw allows a malicious user with sudoedit permissions to set the owner of an arbitrary file to the user ID of the target user, potentially leading...
The vulnerability of SELinux’s access control system in the Linux operating system allows a perpetrator to trigger a service failure.
The vulnerability of SELinux’ access control system in the Linux operating system is related to pointer arithmetic errors. Exploiting this vulnerability can allow a malicious actor, operating remotely, to cause service failures...
kernel: SELinux netlink permission check bypass
A flaw was found in the Linux kernel’s SELinux LSM hook implementation, where it anticipated the skb would only contain a single Netlink message. The hook incorrectly validated the first Netlink message in the skb only, to allow or deny the rest of the messages within the skb with the granted...
A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine it sets the security attribute to indicate that the category bitmap is present even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel resulting in a denial of service.
