Description
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) for other system processes that rely on reading the SELinux policy.
