kernel: selinux: fix overlayfs mmap() and mprotect() access checks
A flaw was found in the Linux kernel's SELinux security module when handling overlayfs. The existing security model for overlayfs does not properly enforce access controls for mmap and mprotect operations. This oversight could allow a local attacker to bypass intended security policies, potential...
