Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: Wifi: rtw88 – Fix for device leaks upon probe failures. The driver core holds a reference to the USB interface and its parent USB device while the interface is bound to the driver. There is no need to hold additional reference...

CVE-2026-46092

A flaw was found in the Linux kernel's rtw88 Wi-Fi driver. When the 8821CE device is installed on a system where it is on a root bus, the driver's probing routine does not properly check for the existence of a PCI upstream bridge. This oversight can lead to a system crash, resulting in a denial o...

Linux Distros Unpatched Vulnerability : CVE-2026-46092

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - wifi: rtw88: check for PCI upstream bridge existence pciupstreambridge returns NULL if the device is on a root bus. If 8821CE is installed in the system with su...

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 the rtw88 driver not checking whether the PCI upstream bridge exists. This could lead to a crash during...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: wifi: rtw88: use a work to update the rate to avoid RCU warnings. The ieee80211ops::starcupdate function must be atomic, because ieee80211chanbwchange holds a rcuread lock while calling drvstarcupdate. Therefore, a work must b...

SUSE CVE-2025-71273

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: Use devmkmemdup in rtwsetsupportedband Simplify the code by using device managed memory allocations. This also fixes a memory leak in rtwregisterhw. The supported bands were not freed in the error path. Copied from...

CVE-2025-71273

A flaw was found in the Linux kernel's rtw88 Wi-Fi driver. This vulnerability is caused by a memory leak within the rtwregisterhw function, where memory allocated for supported bands is not properly released during error conditions. This could allow a local attacker to exhaust system memory,...

CVE-2025-71273

The CVE-2025-71273 entry concerns the Linux kernel’s rtw88 Wi‑Fi driver. The issue arises from a memory leak in rtw_register_hw(), where memory allocated for supported bands was not freed on error paths. The patch standardizes memory allocation using device-managed memory (devm_kmemdup()) in rtw_...

CVE-2026-31604

A flaw was found in the Linux kernel's rtw88 Wi-Fi driver. This vulnerability occurs when the driver fails to release a reference to a Universal Serial Bus USB device during certain probe errors, such as when descriptor parsing fails. A local attacker could potentially trigger this condition by...

DEBIAN-CVE-2026-31604

CVE-2026-31604

The CVE-2026-31604 issue concerns the Linux kernel’s wifi: rtw88 driver. A memory leak arose because the driver grabbing a reference to the USB device during probe did not release it on all probe errors (e.g., descriptor parsing failures) while the interface remained bound to a driver. The fix dr...
