GHSA-PGCQ-8GRM-5RX9 Paymenter has race condition in payWithCredit() that enables credit double-spend

Summary The credit payment implementation in app/Livewire/Invoices/Show.php executes a pessimistic row lock lockForUpdate outside of an active database transaction. Because MySQL/MariaDB requires an enclosing transaction to enforce row-level locks, the guard is ineffective. Concurrent payment...

Race Condition

Overview Affected versions of this package are vulnerable to Race Condition through the payWithCredit process. An attacker can bypass credit balance restrictions by sending concurrent payment requests, resulting in multiple invoices being paid using the same credit balance. Remediation Upgrade...

CVE-2026-10653

The CVE-2026-10653 issue affects the Zephyr net_buf library (lib/net_buf/buf.c). It relies on non-atomic operations for two reference counters: the per-header buf->ref and the per-data-block ref_count. Under true concurrency, two independent unrefs can observe the same prior value and both tre...

CVE-2026-10653 Non-atomic `net_buf` reference counts cause double-free / free-list corruption under concurrent unref

The Zephyr netbuf library lib/netbuf/buf.c manipulated both of its reference counts -- the per-header buf-ref and the per-data-block refcount at the start of each variable/heap data allocation -- with plain non-atomic C operators buf-ref++, if --buf-ref 0, if --refcount. The API is documented as...

CVE-2026-53303

A flaw was found in the Linux kernel's f2fs filesystem. This vulnerability allows for potential out-of-bounds memory access or the display of stale data. It occurs because the extensionlist and related counts are read without proper synchronization, enabling a concurrent system file system sysfs...
