CVE-2024-26587

The CVE-2024-26587 issue in Linux kernel netdevsim could crash when destroying a netdevsim with VFs instantiated. The root cause was that PHC gets initialised in nsim_init_netdevsim() (only called for PF ports), but mock_phc_destroy() was not placed there, leading to a NULL pointer dereference du...

kernel: Linux kernel: Denial of Service due to memory leak in netdevsim

A flaw was found in the Linux kernel's netdevsim component. A local user could exploit a memory leak vulnerability within the nsimbusdevnew function. This occurs when deviceregister fails, leading to an unreleased object name. This memory leak could potentially lead to a Denial of Service DoS on...
