The rmap_remove()\ncall would miss entries created after the PDE change because the GFN\nof the leaf SPTE does not match the GFN of the struct kvm_mmu_page.\n\nA similar hole however remains if the modified PDE points to a non-leaf\npage.  In this case the gfn can be made to match, but the role does not\nmatch: the original large 2MB page creates a kvm_mmu_page with direct=1,\nwhile the new 4KB needs a kvm_mmu_page with direct=0.  However,\nkvm_mmu_get_child_sp() does not compare the role, and therefore reuses\nthe page.\n\nThe next step is installing a leaf (4KB) SPTE on the new path which\nrecords an rmap entry under the gfn resolved by the walk.  But when\nthat child is zapped its parent kvm_mmu_page has direct=1 and\nkvm_mmu_page_get_gfn() computes the gfn for the 4KB page as\nsp-\u003egfn + index instead of using sp-\u003eshadowed_translation[] (or sp-\u003egfns[]\nin older kernels).  It therefore fails to remove the recorded entry.\n\nWhen the memslot is dropped the shadow page is freed but the rmap\nentry survives, as in the scenario that was already fixed.  Code that\nlater walks that gfn (dirty logging, MMU notifier invalidation, and\nso on) dereferences an sptep that lies in the freed page, causing the\nuse-after-free.",

When\nfraggap is non-zero, this is not the first skb and transhdrlen is zero.\nThe fraggap bytes carried over from the previous skb are copied just past\nthe fragment headers in the new skb\u0027s linear area. The linear area is\ntherefore undersized by fraggap bytes while pagedlen is overstated by the\nsame amount, and the copy writes past skb-\u003eend into the trailing\nskb_shared_info.\n\nAn unprivileged user can trigger this via a UDPv6 socket using\nMSG_MORE together with MSG_SPLICE_PAGES.\n\nThe bad accounting was introduced by commit 773ba4fe9104 (\"ipv6:\navoid partial copy for zc\"). Before commit ce650a166335 (\"udp6: Fix\n__ip6_append_data()\u0027s handling of MSG_SPLICE_PAGES\"), the negative\ncopy value caused -EINVAL to be returned. That later commit allowed\nMSG_SPLICE_PAGES to proceed in this case, making the corruption\ntriggerable.\n\nThe non-paged branch sets alloclen to fraglen, which already accounts\nfor fraggap because datalen does. Bring the paged branch in line by\nadding fraggap to alloclen and subtracting it from pagedlen.\n\nAfter this adjustment, copy no longer collapses to -fraggap on the\npaged path, so remove the stale comment describing that old arithmetic.\nSince a negative copy is no longer expected for a valid MSG_SPLICE_PAGES\ncase, remove the MSG_SPLICE_PAGES exception from the negative copy check.",

CVE-2026-53359 (GCVE-0-2026-53359)

Vulnerability from cvelistv5 – Published: 2026-07-04 11:51 – Updated: 2026-07-08 03:56

Title

KVM: x86: Fix shadow paging use-after-free due to unexpected role

Summary

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Fix shadow paging use-after-free due to unexpected role Commit 0cb2af2ea66ad ("KVM: x86: Fix shadow paging use-after-free due to unexpected GFN") fixed a shadow paging mismatch between stored and computed GFNs; the bug could be triggered by changing a PDE mapping from outside the guest, and then deleting a memslot. The rmap_remove() call would miss entries created after the PDE change because the GFN of the leaf SPTE does not match the GFN of the struct kvm_mmu_page. A similar hole however remains if the modified PDE points to a non-leaf page. In this case the gfn can be made to match, but the role does not match: the original large 2MB page creates a kvm_mmu_page with direct=1, while the new 4KB needs a kvm_mmu_page with direct=0. However, kvm_mmu_get_child_sp() does not compare the role, and therefore reuses the page. The next step is installing a leaf (4KB) SPTE on the new path which records an rmap entry under the gfn resolved by the walk. But when that child is zapped its parent kvm_mmu_page has direct=1 and kvm_mmu_page_get_gfn() computes the gfn for the 4KB page as sp->gfn + index instead of using sp->shadowed_translation[] (or sp->gfns[] in older kernels). It therefore fails to remove the recorded entry. When the memslot is dropped the shadow page is freed but the rmap entry survives, as in the scenario that was already fixed. Code that later walks that gfn (dirty logging, MMU notifier invalidation, and so on) dereferences an sptep that lies in the freed page, causing the use-after-free.

The rmap_remove()\ncall would miss entries created after the PDE change because the GFN\nof the leaf SPTE does not match the GFN of the struct kvm_mmu_page.\n\nA similar hole however remains if the modified PDE points to a non-leaf\npage.  In this case the gfn can be made to match, but the role does not\nmatch: the original large 2MB page creates a kvm_mmu_page with direct=1,\nwhile the new 4KB needs a kvm_mmu_page with direct=0.  However,\nkvm_mmu_get_child_sp() does not compare the role, and therefore reuses\nthe page.\n\nThe next step is installing a leaf (4KB) SPTE on the new path which\nrecords an rmap entry under the gfn resolved by the walk.  But when\nthat child is zapped its parent kvm_mmu_page has direct=1 and\nkvm_mmu_page_get_gfn() computes the gfn for the 4KB page as\nsp-\u003egfn + index instead of using sp-\u003eshadowed_translation[] (or sp-\u003egfns[]\nin older kernels).  It therefore fails to remove the recorded entry.\n\nWhen the memslot is dropped the shadow page is freed but the rmap\nentry survives, as in the scenario that was already fixed.

CVE-2026-53362 (GCVE-0-2026-53362)

Vulnerability from cvelistv5 – Published: 2026-07-04 11:56 – Updated: 2026-07-04 11:56

Title

ipv6: account for fraggap on the paged allocation path

Summary

In the Linux kernel, the following vulnerability has been resolved: ipv6: account for fraggap on the paged allocation path In __ip6_append_data(), when the paged-allocation branch is taken (MSG_MORE / NETIF_F_SG / large fraglen), alloclen and pagedlen are computed as alloclen = fragheaderlen + transhdrlen; pagedlen = datalen - transhdrlen; datalen already includes fraggap (datalen = length + fraggap). When fraggap is non-zero, this is not the first skb and transhdrlen is zero. The fraggap bytes carried over from the previous skb are copied just past the fragment headers in the new skb's linear area. The linear area is therefore undersized by fraggap bytes while pagedlen is overstated by the same amount, and the copy writes past skb->end into the trailing skb_shared_info. An unprivileged user can trigger this via a UDPv6 socket using MSG_MORE together with MSG_SPLICE_PAGES. The bad accounting was introduced by commit 773ba4fe9104 ("ipv6: avoid partial copy for zc"). Before commit ce650a166335 ("udp6: Fix __ip6_append_data()'s handling of MSG_SPLICE_PAGES"), the negative copy value caused -EINVAL to be returned. That later commit allowed MSG_SPLICE_PAGES to proceed in this case, making the corruption triggerable. The non-paged branch sets alloclen to fraglen, which already accounts for fraggap because datalen does. Bring the paged branch in line by adding fraggap to alloclen and subtracting it from pagedlen. After this adjustment, copy no longer collapses to -fraggap on the paged path, so remove the stale comment describing that old arithmetic. Since a negative copy is no longer expected for a valid MSG_SPLICE_PAGES case, remove the MSG_SPLICE_PAGES exception from the negative copy check.
