Name of the Vulnerable Software and Affected Versions: ckb affected versions not specified Description: The issue arises from multiple type conversions in ckb that unsafely cast between byte pointers and other types of pointers, resulting in unaligned pointers. This is considered undefined behavi...
unsafe-libyaml unaligned write of u64 on 32-bit and 16-bit platforms
Affected versions allocate memory using the alignment of usize and write data to it of type u64, without using core::ptr::writeunaligned. In platforms with sub-64bit alignment for usize including wasm32 and x86 these writes are insufficiently aligned some of the time. If using an ordinary optimiz...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue is related to the Linux kernel's mhi component, where an unaligned read pointer in the event ring could lead to multiple issues like Denial of Service DoS or ring buffer memory...
GHSA-JCR6-4FRQ-9GJJ Users vulnerable to unaligned read of `*const *const c_char` pointer
Affected versions dereference a potentially unaligned pointer. The pointer is commonly unaligned in practice, resulting in undefined behavior. In some build modes, this is observable as a panic followed by abort. In other build modes the UB may manifest in some other way, including the possibilit...

GHSA-G98V-HV3F-HCFR atty potential unaligned read
On windows, atty dereferences a potentially unaligned pointer. In practice however, the pointer won't be unaligned unless a custom global allocator is used. In particular, the System allocator on windows uses HeapAlloc, which guarantees a large enough alignment. atty is Unmaintained A Pull Reques...
kernel: ext4: avoid resizing to a partial cluster size
In the Linux kernel, the following vulnerability has been resolved: ext4: avoid resizing to a partial cluster size This patch avoids an attempt to resize the filesystem to an unaligned cluster boundary. An online resize to a size that is not integral to cluster size results in the last iteration...
SUSE CVE-2007-6441
The WiMAX dissector in Wireshark formerly Ethereal 0.99.6 allows remote attackers to cause a denial of service crash via unknown vectors related to "unaligned access on some platforms."...
SUSE CVE-2015-2672
The xsave/xrstor implementation in arch/x86/include/asm/xsave.h in the Linux kernel before 3.19.2 creates certain .altinstrreplacement pointers and consequently does not provide any protection against instruction faulting, which allows local users to cause a denial of service panic by triggering ...

An issue was discovered in LibVNCServer before 0.9.13. libvncserver/wsdecode.c can lead to a crash because of unaligned accesses in hybiReadAndDecode...
SUSE CVE-2021-4155
A data leak flaw was found in the way XFSIOCALLOCSP IOCTL in the XFS filesystem allowed for size increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS filesystem otherwise not accessible to them...
SUSE CVE-2022-23639
crossbeam-utils provides atomics, synchronization primitives, scoped threads, and other utilities for concurrent programming in Rust. crossbeam-utils prior to version 0.8.7 incorrectly assumed that the alignment of i,u64 was always the same as AtomicI,U64. However, the alignment of i,u64 on a...

The vulnerability of the `sysdeps/i386/i686/multiarch/memcpy-sse2-unaligned.S` component of the GNU C Library allows a perpetrator to gain access to confidential data, compromise its integrity, and cause service failures.
The vulnerability of the sysdeps/i386/i686/multiarch/memcpy-sse2-unaligned.S component of the GNU C Library is related to the execution of operations outside of the buffer boundaries in memory. Exploiting this vulnerability allows an attacker to gain access to confidential data, compromise its...
