CVE-2026-46071

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Avoid clearing VMCBLBR in vmcb12 svmcopylbrs always marks VMCBLBR dirty in the destination VMCB. However, nestedsvmvmexit uses it to copy LBRs to vmcb12, and clearing clean bits in vmcb12 is not architecturally defined...

CVE-2026-46063

The CVE-2026-46063 issue affects the Linux kernel with x86 shadow stack (shstk) handling of sigreturn. Root cause: during a shadow-stack sigframe read, the kernel previously held the mmap lock while verifying VMA flags to distinguish shadow stack memory. A page fault during this read could trigge...

CVE-2026-46014 KVM: SVM: Add missing save/restore handling of LBR MSRs

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Add missing save/restore handling of LBR MSRs MSRIA32DEBUGCTLMSR and LBR MSRs are currently not enumerated by KVMGETMSRINDEXLIST, and LBR MSRs cannot be set with KVMSETMSRS. So save/restore is completely broken. Fix it ...

CVE-2026-45853 drm/amdgpu: Use kvfree instead of kfree in amdgpu_gmc_get_nps_memranges()

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Use kvfree instead of kfree in amdgpugmcgetnpsmemranges amdgpudiscoverygetnpsinfo internally allocates memory for ranges using kvcalloc, which may use vmalloc for large allocation. Using kfree to release vmalloc memor...

CVE-2026-45850 ipvs: skip ipv6 extension headers for csum checks

In the Linux kernel, the following vulnerability has been resolved: ipvs: skip ipv6 extension headers for csum checks Protocol checksum validation fails for IPv6 if there are extension headers before the protocol header. iph-len already contains its offset, so use it to fix the problem...

CVE-2026-45837

CVE-2026-45837 : In the Linux kernel, a use-after-free in arena_vm_close on fork was fixed. The root cause is that arena_vm_open() only bumps vml->mmap_count and does not register the child VMA in arena->vma_list, so vml->vma continues to point to the parent VMA after fork. If the child ...
