libvirt: Integer overflow in NodeGetFreePages RPC handler leading to heap buffer overflow

A flaw was found in libvirt. An unprivileged local user could exploit an integer overflow vulnerability in the NodeGetFreePages RPC handler. This flaw allows crafted values to bypass a size check, leading to an undersized memory buffer. Subsequently, real NUMA node data can overwrite this buffer...

CVE-2026-25290

CVE-2026-25290 is an Integer Overflow or Wraparound vulnerability in Qualcomm OOBM (Out-of-Bounds Memory). The root cause lies in memory corruption when validating large data buffers from external sources, where an addition operation is used to check buffer length, allowing an integer overflow to...
