CVE-2026-98878

The Linux kernel 's GICv5 driver contains a vulnerability where the priority drop (via the GIC CDEOI system instruction) was incorrectly performed as part of irq_eoi(). Because all interrupts are programmed with the same priority, a long-running process—such as software-injected interrupts for a ...

CVE-2026-98877

In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v4: Don't advertise VLPIs if no ITS is probed When accidentally setting “kvm-arm.vgicv4enable=1” on a system that has no MSI controller device tree node and GICv4, it results a panic as “gicdomain” is NULL and the...

CVE-2026-98877

The Linux kernel contains a vulnerability where setting kvm-arm.vgic_v4_enable=1 on a system with GICv4 but no MSI controller device tree node causes a kernel panic . The root cause is a NULL pointer dereference because the kernel attempts to access gic_domain when it is NULL. The fix involves se...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v4: Do not allow a VMOVP operation on a VPE that is already being unmapped, when the corresponding doorbell interrupt is still visible in /proc/irq/. Kunkun Jiang reported that there is a small window of opportunity f...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: arm64: acpi: Harden the getcpuforacpiid function to prevent errors when a missing CPU entry is used. During a review discussion of the changes to support vCPU hotplug, it was noted that a check was added to ensure the GICC Global...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v3-its: A leak has been prevented in itsvpeirqdomainalloc. When itsirqgicdomainalloc fails, itsvpeirgdomainfree fails to invoke itsvepteardown for the corresponding interrupt, resulting in a resource leak. Invoke...

CVE-2026-90121

A flaw was found in the Linux kernel's irqchip/gic-v5 component. During the setup or teardown of Interrupt Routing System IRS affinity, the system may fail to properly clear pointers to freed memory. This can result in central processing units CPUs attempting to access memory that has already bee...

CVE-2026-90120

A flaw was found in the Linux kernel's GIC-v5 interrupt controller component. The gicacpiparseiaffid function does not properly validate the return value from getlogicalindex. This can lead to out-of-bounds memory corruption when processing Advanced Configuration and Power Interface ACPI data,...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: irqchip/gic-v3: A refcount leak was fixed in gicpopulateppipartitions. The offindnodebyphandle function returns a node pointer with a incremented refcount. We should use ofnodeput on it when there is no longer a need for it. A...
