Improper Locking vulnerability (CWE-667) in Gallagher Morpho integration allows a privileged operator to cause a limited denial-of-service in the Command Centre Server. This issue affects Command Centre Server: 9.40 prior to vEL9.40.1976(MR1), 9.30 prior to vEL9.30.3382 (MR4), 9.20 prior to vEL9.20.3783 (MR6), 9.10 prior to vEL9.10.4647 (MR9), all versions of 9.00 and prior.

CVE-2026-111879—6.8%
——2DBI versions before 1.656 for Perl hang on a later open of a DBD::DBM table because a failed open_data does not release the table's lock.
open_data creates the table's lock file and takes an exclusive flock on it for a CREATE, before the checks that can croak: a dbm_mldbm value that is not a module name, a failing tie, or a missing data file. The croak unwinds before the table object is blessed, so nothing releases the lock, and the meta data holding the open descriptor stays cached on the database handle.
The dbm_mldbm and dbm_type values come from the DSN or the connect attributes, so a caller that chooses the serializer or the storage backend can trigger the failure.
The flock has no timeout, so a later open of that table (even through a separate database handle) blocks for as long as the handle holding the stale lock lives, in the same process or any other.1dCVE-2026-1076745.1 MED0.0%
——0IBM i 7.3, 7.4, 7.5, and 7.6 is vulnerable to a denial of service to Digital Certificate Manager (DCM) for System TLS using applications attempting to create secure network connections. A bad actor could use this to prevent a service from starting or cause it to fallback to non-secure connections.3dCVE-2026-1036707.5 HIG11.3%
——3When a Gitea Actions run was inserted, older runs in the same workflow-level concurrency group were cancelled without checking whether the new run still needed approval. Because fork pull request runs are inserted under the base repository, a user who can open a pull request from a fork could cancel trusted in-progress runs that share a concurrency group with `cancel-in-progress` enabled, without approval and without running any code. On self-hosted runners this can interrupt deployments and leave partial state behind.7dCVE-2026-1051136.5 MED9.1%
——3Nezha Dashboard from 1.8.0 before 2.3.13 contains an improper locking vulnerability where a non-deferred mutex unlock leaks on a nil-map panic path. Any authenticated non-admin member can issue four notification API calls to permanently deadlock the alerting subsystem, then exhaust memory with blocking requests.17dCVE-2026-962735.5 MED0.7%
——0Ghidra before 12.1.4 fails to validate the TYPE_COL byte in OptionsDB.createUnregisteredOption(), causing an ArrayIndexOutOfBoundsException that leaves domain objects permanently locked. Attackers can craft a malicious program database file that, when imported, causes the application to stall and prevents resource cleanup or graceful shutdown.24dCVE-2026-569148.4 HIG0.2%
——0In multiple locations, there is a possible use-after-free due to improper locking. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.31d
