CVE-2024-42126 powerpc: Avoid nmi_enter/nmi_exit in real mode interrupt.

In the Linux kernel, the following vulnerability has been resolved: powerpc: Avoid nmienter/nmiexit in real mode interrupt. nmienter/nmiexit touches per cpu variables which can lead to kernel crash when invoked during real mode interrupt handling e.g. early HMI/MCE interrupt handler if percpu...

CVE-2024-42126

CVE-2024-42126 pertains to the Linux kernel on powerpc where nmi_enter/nmi_exit can touch per-CPU state and crash the kernel when invoked during real-mode interrupt handling if percpu allocations come from the vmalloc area. The issue manifests under CONFIG_NEED_PER_CPU_PAGE_FIRST_CHUNK with percp...

CVE-2024-38663

CVE-2024-38663 (Linux kernel) affects the blk-cgroup iostat/stat reset path. After commit 3b8cc6298724, each iostat instance is added to the blkcg per-CPU list, so blkcg_reset_stats() can’t reset the stat instance by memset(), risking list corruption. The fix is to reset only the counter portion,...
