PHP could be made to crash or run programs if it received specially crafted network traffic.
It was discovered that PHP incorrectly handled SOAP object deduplication when processing apache:Map nodes with duplicate keys. An attacker could possibly use this to cause a use-after-free, resulting in remote code execution. ( CVE-2026-6722 ) It was discovered that PHP incorrectly handled SOAP request persistence when configured with SOAP_PERSISTENCE_SESSION. An attacker could possibly use this to cause a use-after-free, resulting in memory corruption, information disclosure, or a denial of service. ( CVE-2026-7261 ) It was discovered that the PDO Firebird driver in PHP improperly handled NUL bytes when quoting SQL query strings. An attacker could possibly use this to perform SQL injection when attacker-controlled values are embedded in SQL statements. ( CVE-2025-14179 )

In general, a standard system update will make all the necessary changes.
The problem can be corrected by updating your system to the following package versions:
Ubuntu Pro provides ten-year security coverage to 25,000+ packages in Main and Universe repositories, and it is free for up to five machines.
