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...

Astra Linux – Vulnerability in libheif

libheif is a decoder and encoder for HEIF and AVIF file formats. Prior to version 1.21.0, a crafted HEIF file that used overlay image item paths triggered a heap buffer overflow in HeifPixelImage::overlay. This function calculated a negative row length likely derived from an unclipped overlay...
