CVE-2026-76919 is a medium severity vulnerability in Wireshark affecting versions 4.4.0 and 4.6.0. It involves a use of uninitialized variable in the ESS protocol dissector, which can cause the application to crash and result in a denial of service condition.

IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to cause a denial of service due to the use of an uninitialized variable.

CVE-2026-19212 is a low-severity vulnerability in WonderTrader up to version 0.9.9. It involves a use of uninitialized variable triggered by manipulation of the m_offsetType argument in the TraderATP Cash Trade Conversion component. The vulnerability can be exploited remotely. The vendor has not responded to the disclosure, and no patch or remediation information is available.

In NLnet Labs Unbound 1.7.0 up to and including 1.25.1, when the 'dnscrypt:' clause lists more 'dnscrypt-provider-cert:' files than there are matching 'dnscrypt-secret-key:' files, Unbound fills only the matched prefix and leaves the tail slots at the '0xdb' fill that libsodium's allocator writes into every allocation. Unbound would then iterate over the number of cert files, not the actual slots, so it walks into a slot with garbage data filled with '0xdb' bytes. Any unauthenticated client that sends one UDP datagram of ≥ 68 bytes whose first 8 bytes are '0xdb' to 'dnscrypt-port' will use that garbage entry which leads to a garbage dereference killing the server. This is a silent faulty configuration that goes unnoticed until triggered with the right client query. Unbound needs to be compiled with DNSCrypt support ('--enable-dnscrypt').
