Summary
kernel security update
Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

A memory address truncation vulnerability exists in the irqchip/gic-v3-its driver of the Linux kernel. On 32-bit ARM machines with CONFIG_ARM_LPAE enabled, when using larger VMSPLIT configurations, lowmem allocations may be backed by physical memory addresses above the 32-bit address limit. The GICv3 driver allocates the 'itt' object using GFP_KERNEL. Since all memory below the 4GB physical address limit is in ZONE_DMA in this configuration, kmalloc() defaults to higher addresses in ZONE_NORMAL. However, the driver stores these physical addresses in 32-bit 'unsigned long' variables, causing the high addresses to be truncated, which leads to system crashes.(CVE-2026-23085)
