CVE-2026-33278 Possible arbitrary code execution during DNSSEC validation

NLnet Labs Unbound 1.19.1 up to and including version 1.25.0 has a vulnerability in the DNSSEC validator that enables denial of service and possible remote code execution as a result of deep copying a data structure and erroneously overwriting a destination pointer. An adversary can exploit the...

CVE-2026-33278

NLnet Labs Unbound 1.19.1–1.25.0 contains a vulnerability in the DNSSEC validator: during NSEC3-budget–driven validation suspensions, Unbound deep-copies response messages and a struct-assignment overwrites the destination pointer with the source pointer. After freeing the sub-query region, the v...

CVE-2026-43472

The CVE describes a Linux kernel unshare(2) bug: when CLONE_NEWNS is requested and current->fs wasn’t previously shared, copy_mnt_ns() could receive a non-private fs_struct. If copy_mnt_ns() succeeds but a subsequent copy_cgroup_ns() fails, the destroyed namespace can leave current->fs->...

SUSE CVE-2026-43115

In the Linux kernel, the following vulnerability has been resolved: srcu: Use irqwork to start GP in tiny SRCU Tiny SRCU's srcugpstartifneeded directly calls schedulework, which acquires the workqueue pool-lock. This causes a lockdep splat when callsrcu is called with a scheduler lock held, due t...

Potential out-of-bounds write via public `Context` fields

The Context struct has all fields public pub dlen, pub digest, etc.. Code from other modules within the same crate can directly modify dlen to a value exceeding the digest vector length. When reset is subsequently called, self.digestself.dlen as usize = 0 becomes an out-of-bounds write. Withdrawa...
