CVE-2026-68174

A flaw was found in the Linux kernel's tracing subsystem. When handling dynamic events, a memory collision occurs where a reference counter is mistakenly interpreted as a module pointer. This can happen when filtering or setting events for a specific module without properly checking the event's...

EUVD-2026-55275

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix union collision of module and refcnt for dynamic events In 'struct traceeventcall', the 'module' pointer and the 'refcnt' atomic variable share the same memory space in a union. For dynamic events, the union member i...

The vulnerability of the `rxrpcdestroy_call()` function in the `net/rxrpc/call_object.c` module, which supports RxRPC session sockets in the Linux operating system, allows a attacker to cause a service failure.

The vulnerability of the rxrpcdestroycall function in the net/rxrpc/callobject.c module, which supports RxRPC session sockets in Linux kernels, is related to errors during the update of the reference counter. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2026-64345

A flaw was found in the Linux kernel's USB printer gadget driver. The printeropen function incorrectly increments a reference counter even when the device is already in use and the open operation fails. This prevents the reference from being properly released, leading to a permanent leak of syste...
