CVE-2026-93239 arm64: mm: Fix the lockless page-table walk in show_pte()

In the Linux kernel, the following vulnerability has been resolved: arm64: mm: Fix the lockless page-table walk in showpte showpte walks page tables locklessly and can run with interrupts enabled. A concurrent teardown can free a table page while it is being walked. It can also clear a parent ent...

CVE-2026-93211 nfsd: initialize DRC hash table before registering shrinker

In the Linux kernel, the following vulnerability has been resolved: nfsd: initialize DRC hash table before registering shrinker shrinkerregister precedes the INITLISTHEAD loop and the drchashsize store.
