AMD CPU 安全漏洞

AMD CPUs are a family of CPUs from AMD. The AMD CPUs suffer from a competitive condition vulnerability that arises from improper handling of concurrent access when concurrent code requires mutually exclusive access to shared resources during operation of a networked system or product. An attacker...

CPU hardware utilizing speculative execution may be vulnerable to speculative race conditions

Overview A Speculative Race Condition SRC vulnerability that impacts modern CPU architectures supporting speculative execution has been discovered. CPU hardware utilizing speculative execution that are vulnerable to Spectre v1 are likely affected. An unauthenticated attacker can exploit this...

UBUNTU-CVE-2023-52487

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix peer flow lists handling The cited change refactored mlx5etcdelfdbpeerflow to only clear DUP flag when list of peer flows has become empty. However, if any concurrent user holds a reference to a peer flow for...

*const c_void / ExternalPointer unsoundness leading to use-after-free

Summary Use of inherently unsafe const cvoid and ExternalPointer leads to use-after-free access of the underlying structure, resulting in arbitrary code execution. Details const cvoid and ExternalPointer defined via external! macros types are used to represent v8::External wrapping arbitrary void...

BIT-TOMCAT-2021-43980 Apache Tomcat: Information disclosure

The simplified implementation of blocking reads and writes introduced in Tomcat 10 and back-ported to Tomcat 9.0.47 onwards exposed a long standing but extremely hard to trigger concurrency bug in Apache Tomcat 10.1.0 to 10.1.0, 10.0.0 to 10.0.18, 9.0.0 to 9.0.60 and 8.5.0 to 8.5.77 that could...

BIT-GOLANG-2023-39325 HTTP/2 rapid reset can cause excessive work in net/http

A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive server resource consumption. While the total number of requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create a ne...

SUSE CVE-2021-47088

In the Linux kernel, the following vulnerability has been resolved: mm/damon/dbgfs: protect targets destructions with kdamondlock DAMON debugfs interface iterates current monitoring targets in 'dbgfstargetidsread' while holding the corresponding 'kdamondlock'. However, it also destructs the...

UBUNTU-CVE-2023-52524

In the Linux kernel, the following vulnerability has been resolved: net: nfc: llcp: Add lock when modifying device list The device list needs its associated lock held when modifying it, or the list could become corrupted, as syzbot discovered...

CVE-2023-52578

CVE-2023-52578 affects the Linux kernel, specifically in the bridge code path (net/bridge) where br_handle_frame_finish() can race across CPUs, risking data races on dev->stats fields. The fix adopts SMP-safe DEV_STATS_INC() to update dev->stats (including tx_dropped) safely across CPUs, mi...

Linux kernel security vulnerabilities

Linux kernel is the kernel used by the Linux Foundation's open source operating system Linux. A security vulnerability exists in the Linux kernel, which stems from the fact that although this code is executed while holding a waitlock, the reader can acquire a lock without holding a waitlock...

Fedora 39 : golang-github-facebook-time (2024-07c811c7a5)

The remote Fedora 39 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-07c811c7a5 advisory. Security fix for CVE-2023-39325 Tenable has extracted the preceding description block directly from the Fedora security advisory. Note that Nessus h...

The vulnerability of the rose_ioctl() function in the net/rose/af_rose.c module, which is part of the Amateur Radio X.25 PLP (Rose) protocol implementation in the Linux operating system, allows a hacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the roseioctl function in the net/rose/afrose.c module, which is part of the Amateur Radio X.25 PLP Rose protocol implementation in the Linux operating system, relates to the reallocation of previously freed memory due to concurrent access to resources. Exploiting this...
