CVE-2026-18796 QSPI flash encryption side-channel leakage

Any application that uses external QSPI flash for encrypted XIP on nRF5340 and relies on that encryption for confidentiality and/or integrity of the externally stored code. No specific nRF Connect SDK version is the root cause; the weakness is in the on-the-fly decryption scheme...

CVE-2026-18796

CVE-2026-18796 affects the nRF5340 (Nordic Semiconductor) when using external QSPI flash for encrypted XIP (eXecute In Place). The weakness lies in the on-the-fly decryption scheme , not in any specific nRF Connect SDK version, making it a side-channel leakage vulnerability. An attacker with phys...

Name of the Vulnerable Software and Affected Versions strongSwan versions 4.6.2 through 6.0.7 Description An infinite loop occurs during PKCS5 decryption, which is a standard for password-based encryption. Recommendations Update strongSwan versions 4.6.2 through 6.0.7 to a newer version that...

EUVD-2026-70819

A hard-coded cryptographic key vulnerability exists in the web module of TP-Link Archer AX55 v4. A LAN attacker who captures an HTTP login session may use the known shared RSA private key to decrypt the administrator password; the weakened AES session key further reduces the effort required to...

CVE-2026-80831: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: crypto: mxs-dcp - fix source scatterlist length access mxsdcpaesblockcrypt uses sgdmalen without mapping the source scatterlist with dmamapsg first. Therefore, sgdmalen is invalid and could return zero or a stale DMA length,...
