The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, stemming from an initialization order issue with ext4percpuparaminit, which could lead to system crashes...

CVE-2022-26523

The CVE-2022-26523 issue affects the Avast/AVG Anti‑Rootkit driver aswArPot.sys (Windows). It is a local, kernel‑mode vulnerability caused by a double fetch at aswArPot+0xbb94, enabling a user with limited privileges to run code at kernel level or trigger memory corruption/OS crash. Connected doc...

CVE-2026-43275

A flaw was found in the Linux kernel's Universal Flash Storage UFS core driver. A race condition can occur during system suspend when the runtime power management RPM level is set to zero. This allows the driver to attempt to access the host controller after the system has entered a deep power-do...

CVE-2026-43249

A flaw was found in the Linux kernel's 9p/xen filesystem driver. A race condition can occur when the xenwatch thread and other back-end change notifications concurrently attempt to free the front-end state using the xen9pfsfrontfree function. This can lead to a double-free vulnerability, resultin...

CVE-2026-43137

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture on Chip ASoC Sound Open Firmware SOF Intel High Definition Audio HDA subsystem. This flaw occurs when there is a mismatch between the Digital Audio Interface DAI links in the machine driver and the audio topology, leading to...

CVE-2026-43128

A flaw was found in the Linux kernel's RDMA/umem subsystem. A memory management error, specifically a double unpin of a dmabuf, can occur in a failure path during dmabuf pinning operations. This vulnerability could lead to system instability or a crash, resulting in a Denial of Service DoS...

CVE-2026-43124

A flaw was found in the Linux kernel's pstore ramcore component. A local attacker could exploit a vulnerability where the persistentrambuffermap function incorrectly returns success even when the underlying vmap memory mapping operation fails. This occurs if a non-zero offset is used, leading to...

CVE-2025-71293

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. This vulnerability occurs when the EEPROM Electrically Erasable Programmable Read-Only Memory contains only invalid address entries, causing a critical data allocation to be skipped. This leads to a NULL pointer dereference, which can...

CVE-2026-43095

A flaw was found in the Linux kernel's ASoC SDCA subsystem. This vulnerability involves improper cleanup of Interrupt ReQuests IRQs when a sound card is removed. This can lead to IRQ handlers attempting to access invalid memory, which may cause a system crash and result in a Denial of Service DoS...

CVE-2026-43275

In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: core: Flush exception handling work when RPM level is zero Ensure that the exception event handling work is explicitly flushed during suspend when the runtime power management level is set to UFSPMLVL0. When the RPM...

fontconfig: Fontconfig: Security flaw allows arbitrary code execution or system crash

A flaw was found in fontconfig. This vulnerability, an off-by-one error in how fontconfig handles font capabilities, could allow a local attacker to cause a one-byte out-of-bounds write. This issue may lead to a system crash, resulting in a Denial of Service DoS, or potentially enable the attacke...

CImg 安全漏洞

CImg is a small open-source C++ toolkit for image processing, developed by GREYC. CImg has a security vulnerability that stems from the lack of validation of the nbcolors field in BMP file headers. This vulnerability may lead to excessive memory allocation and cause a system to crash due to...

CVE-2026-31728

A flaw was found in the Linux kernel's usb: gadget: uether module. A race condition between the getherdisconnect and ethstop functions can lead to a NULL pointer dereference. This occurs when ethstop is triggered concurrently while getherdisconnect is tearing down USB endpoints. The vulnerability...

CVE-2026-31701

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA caiaq driver. This vulnerability arises from improper handling of Universal Serial Bus USB device references. When a USB device is disconnected, the driver may attempt to access memory that has already been freed, a...

CVE-2026-43010

A flaw was found in the Linux kernel. A local user could attach a sleepable BPF kprobemulti program, which allows sleepable helper functions, such as bpfcopyfromuser, to be invoked from a non-sleepable context. This incorrect handling can lead to a system crash, resulting in a Denial of Service D...
