CVE-2025-71203

In the Linux kernel, the following vulnerability has been resolved: riscv: Sanitize syscall table indexing under speculation The syscall number is a user-controlled value used to index into the syscall table. Use arrayindexnospec to clamp this value after the bounds check to prevent speculative...

DEBIAN-CVE-2024-50102

In the Linux kernel, the following vulnerability has been resolved: x86: fix user address masking non-canonical speculation issue It turns out that AMD has a "Meltdown Litetm" issue with non-canonical accesses in kernel space. And so using just the high bit to decide whether an access is in user...

UBUNTU-CVE-2024-39499

In the Linux kernel, the following vulnerability has been resolved: vmci: prevent speculation leaks by sanitizing event in eventdeliver Coverity spotted that eventmsg is controlled by user-space, eventmsg-eventdata.event is passed to eventdeliver and used as an index without sanitization. This...

SUSE CVE-2023-52481

In the Linux kernel, the following vulnerability has been resolved: arm64: errata: Add Cortex-A520 speculative unprivileged load workaround Implement the workaround for ARM Cortex-A520 erratum 2966298. On an affected Cortex-A520 core, a speculatively executed unprivileged load might leak data fro...

USN-6388-1 linux, linux-aws, linux-kvm, linux-lts-xenial vulnerabilities

Daniel Moghimi discovered that some IntelR Processors did not properly clear microarchitectural state after speculative execution of various instructions. A local unprivileged user could use this to obtain to sensitive information. CVE-2022-40982 Yang Lan discovered that the GFS2 file system...

Important: kernel

Issue Overview: A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss of confidentiality. CVE-2023-20588 The fix for XSA-423 added logic to Linux'es netback driver to deal with a frontend splitting a packet in a way such that not all of the...

hw: TSX Transaction Asynchronous Abort (TAA)

A flaw was found in the way Intel CPUs handle speculative execution of instructions when the TSX Asynchronous Abort TAA error occurs. A local authenticated attacker with the ability to monitor execution times could infer the TSX memory state by comparing abort execution times. This could allow...

hardware: Microarchitectural Fill Buffer Data Sampling (MFBDS)

A flaw was found in the implementation of the "fill buffer", a mechanism used by modern CPUs when a cache-miss is made on L1 CPU cache. If an attacker can generate a load operation that would create a page fault, the execution will continue speculatively with incorrect data from the fill buffer...
