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 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...

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...
