In the Linux kernel, the following vulnerability has been resolved:
nvdimm: Fix devs leaks in scan_labels()
scan_labels() leaks memory when label scanning fails and it falls back
to just creating a default "seed" namespace for userspace to configure.
Root can force the kernel to leak memory.
Allocate the minimum resources unconditionally and release them when
unneeded to avoid the memory leak.

Title: kernel de Linux
Description: En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nvdimm: Se corrigen las fugas de memoria de los desarrolladores en scan_labels() scan_labels() pierde memoria cuando falla el escaneo de etiquetas y vuelve a crear un espacio de nombres "seed" predeterminado para que el espacio de usuario lo configure. El usuario root puede obligar al kernel a perder memoria. Asigne los recursos mínimos incondicionalmente y libérelos cuando no sean necesarios p
