CVE-2026-63942

In the Linux kernel, the following vulnerability has been resolved: parport: Fix race between port and client registration The parport subsystem registers port devices before they are fully initialised, resulting in a race condition where client drivers such as lp can attach to ports that are not...

CVE-2026-63942

The CVE relates to the Linux kernel parport subsystem where a race occurs between port device registration and client driver attachment (e.g., lp) when ports and clients are built as modules and loaded concurrently during boot. The root cause is that port devices register before full initialisati...

CVE-2026-53373 mm/vma: do not try to unmap a VMA if mmap_prepare() invoked from mmap()

In the Linux kernel, the following vulnerability has been resolved: mm/vma: do not try to unmap a VMA if mmapprepare invoked from mmap The mmapprepare hook functionality includes the ability to invoke mmapprepare from the mmap hook of existing 'stacked' drivers, that is ones which are capable of...

CVE-2026-53373

The CVE-2026-53373 issue is in the Linux kernel’s mm/vma path: in certain stacked driver scenarios, mmap_prepare() invoked from the mmap() hook may expose a not-fully-established VMA to the caller, risking unsafe unmapping as the VMA is detached. The fix propagates the context of the mmap action ...
