CVE-2026-52963

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA USB audio driver. The driver's handling of MIDI Musical Instrument Digital Interface endpoint descriptors did not properly bound scans, allowing it to read beyond the intended memory buffer. This out-of-bounds read coul...

CVE-2026-53084

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This vulnerability involves a lock ordering problem that occurs when BPF programs acquire certain locks that depend on the mmaplock. This issue could potentially lead to system instability or unexpected behavior due to...

CVE-2026-53085

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This use-after-free vulnerability occurs when the taskvma iterator reads task memory without properly acquiring a reference, allowing the memory structure to be freed concurrently while still in use. This can lead to...

CVE-2026-53056

A flaw was found in the Linux kernel's Display Processing Unit DPU driver. During DPU runtime suspend, a mismatch can occur between the power rail voltage and the core clock frequency. This happens when the power management attempts to drop the voltage while the clock remains at its highest rate...

CVE-2026-53213

A flaw was found in the Linux kernel's drm/vc4 component. This vulnerability occurs due to incorrect handling of the krealloc function's return value. If krealloc fails and returns a null value, the original pointer to allocated memory is overwritten without proper validation, leading to a memory...

CVE-2026-53147

A flaw was found in the Linux kernel's Thunderbolt component. A remote attacker could exploit this vulnerability by sending a malformed XDomain packet. This could lead to an out-of-bounds read, potentially resulting in information disclosure or system instability...

CVE-2026-53151

A flaw was found in the Linux kernel's AFRXRPC subsystem. This vulnerability involves incorrect handling of fragmented UDP packets when parsing the SACK Selective Acknowledgment table. An attacker could potentially craft a fragmented UDP packet to trigger an incorrect buffer access within the...

CVE-2026-53160

A flaw was found in the Linux kernel's fastrpc component. A race condition in the fastrpcmapcreate function allows for a use-after-free vulnerability. This could enable an attacker to cause system instability, disclose sensitive information, or potentially execute unauthorized code...

CVE-2026-53203

A flaw was found in the Linux kernel's accel/ivpu component. This vulnerability, a buffer overflow, occurs when the firmware returns a size larger than the allocated buffer during a metric stream information query. This can lead to an incorrect buffer copy, potentially causing system instability ...

CVE-2026-53049

A flaw was found in the Linux kernel's Global File System 2 GFS2 component. The gfs2logd function, responsible for log flushing, calls several log flushing functions without holding the required lock. This omission allows concurrent transactions to access shared resources without proper exclusion...

CVE-2026-53082

A flaw was found in the 6pack hamradio driver within the Linux kernel. This vulnerability occurs because the system does not properly handle data with communication errors, causing it to process uninitialized information. An attacker with local access could potentially exploit this to gain...

CVE-2026-53261

A flaw was found in the devlink component of the Linux kernel. This issue occurs when a devlink instance acquires a nested relation but fails to register, leading to a resource leak. This can result in system instability or a denial of service DoS over time due to resource exhaustion...

CVE-2026-52930

A flaw was found in the Linux kernel's inter-process communication IPC shared memory shm component. A synchronization issue exists where orphaned shared memory segments might be incorrectly destroyed while still in use due to a lack of serialization between cleanup and attachment updates. This...

kernel: wifi: mac80211: remove station if connection prep fails

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. When Multi-Link Operation MLO connection preparation fails, the system may not correctly remove the associated station. This can lead to a use-after-free or double-free vulnerability in the debugfs component, potentially causing...

kernel: netfilter: flowtable: strictly check for maximum number of actions

A flaw was found in the Netfilter flowtable component of the Linux kernel. This vulnerability occurs because the system does not strictly check the maximum number of hardware offload actions for IPv6, allowing it to process more actions than supported. This could potentially lead to system...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: clk: sunxi-ng: h6 – Reparenting the CPUX during PLL CPUX clock rate changes. While changes in the PLL CPUX clock rate when the CPU is running work in the vast majority of cases, occasionally they cause instability. This leads to...

CVE-2026-46330

In the Linux kernel, the following vulnerability has been resolved: Revert "net/smc: Introduce TCP ULP support" This reverts commit d7cd421da9da2cc7b4d25b8537f66db5c8331c40. As reported by Al Viro, the TCP ULP support for SMC is fundamentally broken. The implementation attempts to convert an acti...

PT-2026-47788

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description TCP ULP support for SMC is fundamentally broken. The implementation attempts to convert an active TCP socket into an SMC socket by modifying the underlying struct file, dentry, and inode...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from design flaws in the TCP ULP support implemented in the net/smc module. This vulnerability allows an...

CVE-2026-46311

A flaw was found in the Linux kernel. This vulnerability, located in the drm/amdgpu/userq component, involves improper handling of memory mappings. A local attacker could potentially exploit a race condition during queue creation, where a memory object is unmapped while another is being assigned ...
