libpng: libpng: Arbitrary code execution due to use-after-free vulnerability

A flaw was found in libpng, a library used for processing PNG Portable Network Graphics image files. This vulnerability arises from improper memory management where a heap-allocated buffer is aliased between internal data structures. When specific functions are called, a freed memory region can...

CVE-2026-63979

A flaw was found in the Linux kernel's net/handshake component. A race condition exists where a network handshake request can be removed and its associated file reference released concurrently while the accept-side code attempts to access it. This can lead to the system attempting to read from...

CVE-2026-63927

A flaw was found in the Linux kernel, specifically within the dwc2 USB driver. This vulnerability, known as a use-after-free, occurs when the system attempts to access memory that has already been released. This happens because a USB Request Block urb is incorrectly accessed after it has been...

CVE-2026-64071 nvme-pci: fix use-after-free in nvme_free_host_mem()

In the Linux kernel, the following vulnerability has been resolved: nvme-pci: fix use-after-free in nvmefreehostmem nvmefreehostmem frees dev-hmbsgt via dmafreenoncontiguous but never clears the pointer afterward. This leads to a use-after-free if nvmefreehostmem is called twice in the same error...
