UBUNTU-CVE-2025-71071

In the Linux kernel, the following vulnerability has been resolved: iommu/mediatek: fix use-after-free on probe deferral The driver is dropping the references taken to the larb devices during probe after successful lookup as well as on errors. This can potentially lead to a use-after-free in case...

CVE-2025-71078

In the Linux kernel, the following vulnerability has been resolved: powerpc/64s/slb: Fix SLB multihit issue during SLB preload On systems using the hash MMU, there is a software SLB preload cache that mirrors the entries loaded into the hardware SLB buffer. This preload cache is subject to period...

CVE-2025-71078

CVE-2025-71078 describes a Linux kernel fix for a SLB multihit issue on hash MMU POWERPC 64s. The root cause is a mismatch between the hardware SLB and the software preload cache when the kernel optimizes switch_mm_irqs_off by not calling switch_mmu_context() if prev and next mm_struct are the sa...
