CVE-2023-52494

In the Linux kernel, the following vulnerability has been resolved: bus: mhi: host: Add alignment check for event ring read pointer Though we do check the event ring read pointer by "isvalidringptr" to make sure it is in the buffer range, but there is another risk the pointer may be not aligned...

Linux kernel security vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from an unaligned event ring read pointer, leading to issues such as a denial of service DoS or ring buffer memor...

PT-2024-26754

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue is related to an incorrect number of pages being released for buffers that do not start at the beginning of a page in the Linux kernel. This is fixed by correcting page refcoun...

GHSA-Q669-2VFG-CXCG Nervos CKB Unaligned Pointer Dereference

via [email protected] There are multiple type conversions in ckb that unsafely cast between byte pointers and other types of pointers. This results in unaligned pointers, which are not allowed by the Rust language, and are considered undefined behavior, meaning that the compiler is free to do...

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...

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-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 ...

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...
