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...

SUSE CVE-2020-10726

A vulnerability was found in DPDK versions 19.11 and above. A malicious container that has direct access to the vhost-user socket can keep sending VHOSTUSERGETINFLIGHTFD messages, causing a resource leak file descriptors and virtual memory, which may result in a denial of service...

SUSE CVE-2020-14376

A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A lack of bounds checking when copying ivdata from the VM guest memory into host memory can lead to a large buffer overflow. The highest threat from this vulnerability is to data confidentiality and integrity as well as syst...

SUSE CVE-2022-39188

An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition unmapmappingrange versus munmap, a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VMPFNMAP VMAs...

GO-2023-1559 Denial of service via HAMT decoding panic in github.com/ipfs/go-unixfsnode

Trying to read malformed HAMT sharded directories can cause panics and virtual memory leaks. If you are reading untrusted user input, an attacker can then trigger a panic. This is caused by a bogus fanout parameter in the HAMT directory nodes. There are no known workarounds users are advised to...
