podman: podman machine spawns gvproxy with port bound to all IPs
A flaw was found in podman. The podman machine function used to create and manage Podman virtual machine containing a Podman process spawns a gvproxy process on the host system. The gvproxy API is accessible on port 7777 on all IP addresses on the host. If that port is open on the host's firewall...
kernel: KVM: NULL pointer dereference in kvm_irq_delivery_to_apic_fast()
A flaw was found in the Linux kernel’s KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a...
kernel: gso: do not skip outer ip header in case of ipip and net_failover
In the Linux kernel, the following vulnerability has been resolved: gso: do not skip outer ip header in case of ipip and netfailover We encounter a tcp drop issue in our cloud environment. Packet GROed in host forwards to a VM virtionet nic with netfailover enabled. VM acts as a IPVS LB with ipip...
kernel: KVM: LAPIC: Also cancel preemption timer during SET_LAPIC
A vulnerability was found in the Linux kernel's KVM component related to the LAPIC during the guest reboot process. This issue arises when the SETLAPIC command is issued without exposing the tsc-deadline mode, leading to warnings and potential inconsistencies due to an unhandled preemption timer...
kernel: KVM: cmpxchg_gpte can write to pfns outside the userspace region
A flaw was found in KVM. When updating a guest's page table entry, vmpgoff was improperly used as the offset to get the page's pfn. As vaddr and vmpgoff are controllable by user-mode processes, this flaw allows unprivileged local users on the host to write outside the userspace region and...
kernel: KVM: NULL pointer dereference in kvm_dirty_ring_push in virt/kvm/dirty_ring.c
A NULL pointer dereference issue was found in KVM when releasing a vCPU with dirty ring support enabled. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service...
kernel: powerpc/rtas: Keep MSR[RI] set when calling RTAS
In the Linux kernel, the following vulnerability has been resolved: powerpc/rtas: Keep MSRRI set when calling RTAS RTAS runs in real mode MSRDR and MSRIR unset and in 32-bit big endian mode MSRSF,LE unset. The change in MSR is done in enterrtas in a relatively complex way, since the MSR value cou...
kernel: KVM: x86/mmu: Zap _all_ roots when unmapping gfn range in TDP MMU
In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Zap all roots when unmapping gfn range in TDP MMU Zap both valid and invalid roots when zapping/unmapping a gfn range, as KVM must ensure it holds no references to the freed page after returning from the unmap...
