Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: usb: dwc3-meson-g12a: Fixed an issue where the USB2 PHY glue initialization was performed when PHY0 was disabled. When only PHY1 is used for example, on Odroid-HC4, the regmap initialization code uses USB2 ports without...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: gadget: Replace listforeachentrysafe when using giveback The listforeachentrysafe macro saves the current item n and the item after n+1, so that n can be safely removed without corrupting the list. However, when...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: ep0: fix NULL pointer exception There is no validation of the index from dwc3wIndextodep and we might be referring a non-existing ep and trigger a NULL pointer exception.

CVE-2026-64454

A flaw was found in the Linux kernel's USB dwc3 driver. A local attacker could trigger a condition where a sleeping function is called from an invalid context during a USB gadget suspend operation. This can lead to system instability or a kernel panic, resulting in a Denial of Service DoS...

CVE-2026-64349

A flaw was found in the Linux kernel's USB dwc3 driver. Incorrect type handling in the dwc3readl and dwc3writel functions within dwc3ulpisetup can lead to memory corruption. This vulnerability may allow an attacker to cause system instability or potentially execute arbitrary code, depending on th...
