CVE-2026-99178 is a vulnerability in the Linux kernel's x86 KVM subsystem involving improper handling of asynchronous page fault (async #PF) flags during nested page faults in non-maskable interrupt (NMI) context. This flaw can cause a kernel panic when an async page fault is consumed incorrectly in NMI context, leading to system instability. The issue was resolved by ensuring the async #PF flags are not consumed on a kernel page fault in NMI context, preserving the flags for the interrupted handler. The fix is included in Linux kernel versions 6.18.59 and 7.2.13 and later.
A vulnerability in the Linux kernel's NTFS implementation involves incorrect handling of attribute record resizing. Specifically, the attribute payload was moved after shrinking its record, causing memory copying errors that lead to malformed mapping pairs arrays. This flaw was fixed in Linux kernel version 7.2.13 by changing the order of operations to move the payload before shrinking the record.
