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...

kernel: xen/privcmd: fix double free via VMA splitting

A flaw was found in the Linux kernel's xen/privcmd module. A local user could exploit this by performing a partial unmapping of a privcmd memory region. This action causes a Virtual Memory Area VMA to split, leading to duplicated internal memory pointers. As a result, the same memory can be freed...

httpd: mod_md: unrestricted OCSP response leads to resource exhaustion

A flaw was found in the modmd module of httpd. When processing OCSP Online Certificate Status Protocol responses from a malicious or compromised OCSP responder, the module fails to enforce proper size limits on the incoming data. This issue leads to memory exhaustion and a denial of service...
