CVE-2026-64376

CVE-2026-64376 is a reference-count leak in the Linux kernel's firmware_loader subsystem. In firmware_upload_register(), if alloc_lookup_fw_priv() fails after fw_create_instance() succeeds, the embedded struct device is freed via free_fw_sysfs instead of put_device(), leaving the device refcount ...

In the Linux kernel, the following vulnerability has been resolved: posix-cpu-timers: Fix pid refcount leak in docpunanosleep error path In docpunanosleep, posixcputimercreate takes a pid reference via getpid and stores it in timer.it.cpu.pid. If the subsequent posixcputimerset call fails, the...

CVE-2026-64370

CVE-2026-64370 is a Linux kernel vulnerability in the posix-cpu-timers subsystem. In do_cpu_nanosleep(), the call to posix_cpu_timer_create() acquires a pid reference via get_pid() and stores it in timer.it.cpu.pid. When the subsequent posix_cpu_timer_set() call fails, the function returns withou...

CVE-2026-64345

CVE-2026-64345 affects the Linux kernel USB gadget f_printer driver. The function printer_open() increments dev->kref even when it returns -EBUSY (device already open). Because VFS does not call ->release() for a failed open, every rejected second open permanently leaks one reference count ...

CVE-2026-64301

CVE-2026-64301 is a Linux kernel vulnerability in the SCMI regulator driver . The root cause is an of_node reference count leak in scmi_regulator_probe(): when process_scmi_regulator_of_node() fails, the error path returns without calling of_node_put(), leaking the device node reference. This can...
