Security Fix(es):
cups:

A flaw was found in cups. An attacker with network access to the Internet Printing Protocol (IPP) service can cause a Denial of Service (DoS) by initiating a document submission request and keeping the connection open without completing it. The print scheduler globally pauses timeout processing for all jobs while any document transfer is active, preventing abandoned jobs from expiring. An attacker can repeatedly submit incomplete jobs until the system's job limit is reached, causing legitimate print requests to be rejected.

Threats
Impact
Low
A flaw was found in CUPS. An authenticated user authorized to manage printer classes can cause a Denial of Service (DoS) by triggering a double-free memory error during printer class management. By submitting a class modification request with invalid parameters followed by a class deletion request, the user can crash the print scheduler service.
CWE-1341 - Multiple Releases of Same Resource or HandleAffected products
Fixed
25 products, the same list as for
CVE-2026-107885
Threats
Impact
Low
A flaw was found in CUPS. An attacker with access to the local print service can cause a Denial of Service (DoS) by submitting a held print job targeted at a temporary printer that is subsequently deleted. Because the print scheduler fails to verify that the printer destination still exists before checking the job status, it accesses invalid memory and crashes the cupsd daemon, interrupting all managed print queues.

Affected products
Fixed
25 products, the same list as for
CVE-2026-107885
Threats
Impact
Moderate
A flaw was found in CUPS. An attacker who can submit print jobs can exploit this issue by sending a crafted request containing repeated Internet Printing Protocol (IPP) group tags. This triggers a NULL pointer dereference during job processing, causing the print scheduler daemon (cupsd) to crash and resulting in a Denial of Service (DoS) across all print queues.
