Summary:

Siemens has issued a security advisory regarding a CVSS v4 score 8.2 out-of-bounds read vulnerability affecting several of its products, including S7-PCT, SCT, SIMATIC, SINAMICS, SINUMERIK, and TIA Portal products. An attacker could exploit this vulnerability to cause a Blue Screen of Death (BSOD) crash of the underlying Windows kernel, leading to a denial-of-service condition. Siemens has released updates to mitigate the risk for some products, but others do not have a planned fix. The Cybersecurity and Infrastructure Security Agency (CISA) recommends users minimize network exposure, locate devices behind firewalls, and use secure remote access methods to reduce the risk of exploitation.
