Linux 6.6 Race Condition Exploit
A security-relevant race between mremap and THP code has been discovered. Reaching the buggy code typically requires the ability to create unprivileged namespaces. The bug leads to installing physical address 0 as a page table, which is likely exploitable in several ways: For example, triggering...

kernel: drm/i915/dpt: Make DPT object unshrinkable
In the Linux kernel, the following vulnerability has been resolved: drm/i915/dpt: Make DPT object unshrinkable In some scenarios, the DPT object gets shrunk but the actual framebuffer did not and thus its still there on the DPT's vm-boundlist. Then it tries to rewrite the PTEs via a stale CPU...
kernel: x86/mm/pat: fix VM_PAT handling in COW mappings
CVE-2024-35877 pertains to a flaw in the Linux kernel's handling of Page Attribute Table PAT settings during Copy-On-Write COW operations. When a write operation triggers a COW event, the kernel may replace the original page table entries PTEs with anonymous folios. This replacement disrupts the...
kernel: mm/page_table_check: fix crash on ZONE_DEVICE
A vulnerability was found in the Linux kernel's mm/pagetablecheck component, specifically related to ZONEDEVICE pages. When page-table-check is enabled, attempting to map DAX memory can lead to a kernel crash due to invalid checks on these pages, which do not allocate pageext...
