 ------------------------------------------------------------------------- Debian LTS Advisory DLA-4848-1 [email protected] https://www.debian.org/lts/security/ Guilhem Moulin October 21, 2026 https://wiki.debian.org/LTS
 -------------------------------------------------------------------------

 Package : php8.2 Version : 8.2.35-1~deb12u1 CVE ID : CVE-2026-109618 CVE-2026-109619

 Two critical vulnerabilities were found in PHP, a widely-used open source general purpose scripting language, which could result in remote execution of arbitrary code.

 CVE-2026-109618

 Out-of-memory handling can interrupt PHP while internal request data is only partially initialized. Request cleanup may then treat the invalid data as valid.

 CVE-2026-109619

 Request-owned internal global state can survive after its backing memory has been freed. A later request handled by the same worker may use that stale state before normal initialization resets it.

 For Debian 12 bookworm, these problems have been fixed in version 8.2.35-1~deb12u1.

 We recommend that you upgrade your php8.2 packages.

 For the detailed security status of php8.2 please refer to its security tracker page at:
