kernel: idpf: fix UAFs when destroying the queues

In the Linux kernel, the following vulnerability has been resolved: idpf: fix UAFs when destroying the queues The second tagged commit started sometimes very rarely, but possible throwing WARNs from net/core/pagepool.c:pagepooldisabledirectrecycling. Turned out idpf frees interrupt vectors with...

kernel: pci/hotplug/pnv_php: Fix hotplug driver crash on Powernv

A flaw was found in the Linux kernel's Powernv hotplug driver. This vulnerability allows a local attacker to trigger a system crash by attempting to remove or disable a PCIe device from the system. The issue arises from the driver trying to access a memory location that has already been cleared,...

kernel: net: usb: lan78xx: Fix double free issue with interrupt buffer allocation

A double free vulnerability was found in the Linux kernel. In lan78xxprobe, the buf buffer is freed twice: once implicitly through usbfreeurbdev-urbintr with the URBFREEBUFFER flag and again explicitly by kfreebuf, resulting in loss of availability of the system...

kernel: usb: typec: tipd: Free IRQ only if it was requested before

A flaw was found in the Linux kernel's USB Type-C tipd driver. When the tps6598x module is removed, the system attempts to free an Interrupt Request IRQ even if one was not previously allocated. This improper resource handling can lead to a system warning and potential instability, which may resu...

kernel: gpio: pca953x: fix pca953x_irq_bus_sync_unlock race

In the Linux kernel, the following vulnerability has been resolved: gpio: pca953x: fix pca953xirqbussyncunlock race Ensure that i2clock' is held when setting interrupt latch and mask in pca953xirqbussyncunlock in order to avoid races. The other non-probe call site pca953xgpiosetmultiple ensures t...

In the Linux kernel, the following vulnerability has been resolved: PCI/MSI: Handle lack of irqdomain gracefully Alexandre observed a warning emitted from pcimsisetupmsiirqs on a RISCV platform which does not provide PCI/MSI support: WARNING: CPU: 1 PID: 1 at drivers/pci/msi/msi.h:121...

SUSE CVE-2025-37849

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Tear down vGIC on failed vCPU creation If kvmarchvcpucreate fails to share the vCPU page with the hypervisor, we propagate the error back to the ioctl but leave the vGIC vCPU data initialised. Note only does this leak...

CVE-2025-37885 KVM: x86: Reset IRTE to host control if *new* route isn't postable

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Reset IRTE to host control if new route isn't postable Restore an IRTE back to host control remapped or posted MSI mode if the new GSI route prevents posting the IRQ directly to a vCPU, regardless of the GSI routing typ...

CVE-2025-37885

CVE-2025-37885 affects the Linux kernel KVM/x86, where a dangling IRTE could be left posting to a vCPU if the new GSI route cannot be posted. The issue is fixed by restoring IRTE ownership to the host control when the new route isn’t postable, preventing use-after-free and incorrect interrupt del...

SUSE CVE-2025-37812

In the Linux kernel, the following vulnerability has been resolved: usb: cdns3: Fix deadlock when using NCM gadget The cdns3 driver has the same NCM deadlock as fixed in cdnsp by commit 58f2fcb3a845 "usb: cdnsp: Fix deadlock issue during using NCM gadget". Under PREEMPTRT the deadlock can be...
