kernel: unmap_mapping_range() race with munmap() on VM_PFNMAP mappings leads to stale TLB entry
A flaw was found in include/asm-generic/tlb.h in the Linux kernel due to a race condition unmapmappingrange versus munmap. This issue allows a device driver to free a page while it still has stale TLB entries...

kernel: mm/hugetlb: avoid corrupting page->mapping in hugetlb_mcopy_atomic_pte
In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: avoid corrupting page-mapping in hugetlbmcopyatomicpte In MCOPYATOMICCONTINUE case with a non-shared VMA, pages in the page cache are installed in the ptes. But hugepageaddnewanonrmap is called for them mistakenly...
kernel: KVM: x86: Use __try_cmpxchg_user() to update guest PTE A/D bits
In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Use trycmpxchguser to update guest PTE A/D bits Use the recently introduced trycmpxchguser to update guest PTE A/D bits instead of mapping the PTE into kernel address space. The VMPFNMAP path is broken as it assumes tha...
kernel: drm/amdgpu: Fix use-after-free on amdgpu_bo_list mutex
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix use-after-free on amdgpubolist mutex If amdgpucsvmhandling returns r != 0, then it will unlock the bolistmutex inside the function amdgpucsvmhandling and again on amdgpucsparserfini. This problem results in the...

FreeBSD : py39-unicorn -- sandbox escape and arbitrary code execution vulnerability (17083017-d993-43eb-8aaf-7138f4486d1c)
The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 17083017-d993-43eb-8aaf-7138f4486d1c advisory. - An issue was discovered in splitregion in uc.c in Unicorn Engine before 2.0.0-rc5. It allows local...
kernel: use-after-free related to leaf anon_vma double reuse
A memory leak flaw with use-after-free capability was found in the Linux kernel. The VMA mm/rmap.c functionality in the ismergeableanonvma function continuously forks, using memory operations to trigger an incorrect reuse of leaf anonvma. This issue allows a local attacker to crash the system...
