CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2021-47110 – x86/kvm: Disable kvmclock on all CPUs on shutdown
https://notcve.org/view.php?id=CVE-2021-47110
In the Linux kernel, the following vulnerability has been resolved: x86/kvm: Disable kvmclock on all CPUs on shutdown Currenly, we disable kvmclock from machine_shutdown() hook and this only happens for boot CPU. We need to disable it for all CPUs to guard against memory corruption e.g. on restore from hibernate. Note, writing '0' to kvmclock MSR doesn't clear memory location, it just prevents hypervisor from updating the location so for the short while after write and while CPU is still alive, the clock remains usable and correct so we don't need to switch to some other clocksource. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: x86/kvm: deshabilite kvmclock en todas las CPU al apagar Actualmente, deshabilitamos kvmclock desde el enlace machine_shutdown() y esto solo sucede para la CPU de arranque. Necesitamos deshabilitarlo para todas las CPU para protegernos contra la corrupción de la memoria, por ejemplo, al restaurar desde la hibernación. Tenga en cuenta que escribir '0' en kvmclock MSR no borra la ubicación de la memoria, solo evita que el hipervisor actualice la ubicación, por lo que durante un breve período después de la escritura y mientras la CPU aún está activa, el reloj permanece utilizable y correcto, por lo que no lo necesitamos. para cambiar a alguna otra fuente de reloj. • https://git.kernel.org/stable/c/9084fe1b3572664ad276f427dce575f580c9799a https://git.kernel.org/stable/c/3b0becf8b1ecf642a9edaf4c9628ffc641e490d6 https://git.kernel.org/stable/c/1df2dc09926f61319116c80ee85701df33577d70 https://git.kernel.org/stable/c/c02027b5742b5aa804ef08a4a9db433295533046 •
CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-26625 – llc: call sock_orphan() at release time
https://notcve.org/view.php?id=CVE-2024-26625
In the Linux kernel, the following vulnerability has been resolved: llc: call sock_orphan() at release time syzbot reported an interesting trace [1] caused by a stale sk->sk_wq pointer in a closed llc socket. In commit ff7b11aa481f ("net: socket: set sock->sk to NULL after calling proto_ops::release()") Eric Biggers hinted that some protocols are missing a sock_orphan(), we need to perform a full audit. In net-next, I plan to clear sock->sk from sock_orphan() and amend Eric patch to add a warning.
