Security vulnerabilities and automated fixes for out of bounds read issues

A critical out-of-bounds memory read vulnerability was discovered and patched in a RISC-V emulator's MMU address translation logic, where insufficient bounds validation in `mmu_ifetch` allowed malicious guest programs to read arbitrary host process memory. This class of vulnerability represents one of the most dangerous bugs in virtualization and emulation software, as it breaks the fundamental isolation boundary between guest and host. The fix reinforces address validation before any memory acc
A critical out-of-bounds memory read vulnerability was discovered and patched in libretro-common's network socket abstraction layer, where unsafe memcpy operations on caller-supplied fd_set pointers could lead to heap or stack memory corruption. Attackers or malicious inputs exploiting this flaw could potentially read sensitive memory regions or destabilize the application. The fix introduces proper source-size validation before performing memory copy operations on file descriptor sets.
