SUSE CVE-2026-98396

In the Linux kernel, the following vulnerability has been resolved: powerpc: Do not restore KUAP in archexittousermodeprepare KUAP means kernel cannot touch user memory unless it explicitly is enabled. In the kernel it should stay AMRKUAPBLOCKED. While returning to userspace just before RFI, kern...

CVE-2026-98395

A flaw was found in the Linux kernel's PowerPC architecture. This flaw allows a local user to cause a Denial of Service DoS and system instability. When processing replayed interrupts, the kernel improperly updates its internal interrupt mask, stripping critical status flags and leading to...

CVE-2026-98396

The Linux kernel on PowerPC architecture contains a vulnerability where KUAP (Kernel User Access Prevention) is restored too early during the transition from kernel to user mode. Specifically, the GENERIC_ENTRY feature incorrectly triggered kuap_user_restore() within arch_exit_to_user_mode_prepar...

CVE-2026-98395

The Linux kernel contains a vulnerability in the powerpc architecture's interrupt handling. When __replay_soft_interrupts() replays a pending interrupt, the arch_local_irq_disable() function call unconditionally overwrites the irq_soft_mask with IRQS_DISABLED (0x1), stripping the IRQS_PMI_DISABLE...
