CVE-2026-97540

A flaw was found in the Linux kernel's Pegasus USB Ethernet driver. This vulnerability can lead to a Denial of Service DoS through a system crash. When dynamic device identifiers are configured, the driver improperly uses pointer calculations on heap memory instead of referencing its static devic...

CVE-2026-43156

The CVE-2026-43156 entry affects the Linux kernel USB Pegasus driver. The root cause is that pegasus_probe() built URBs using hardcoded endpoint pipes (RX bulk 1, TX bulk 2, status interrupt 3) without validating endpoint descriptors, allowing a malformed USB device to present endpoints with mism...

The vulnerability of the Linux operating system, which allows a perpetrator to trigger a service failure or cause other effects

The vulnerability in the driver drivers/net/usb/pegasus.c of the Linux operating system arises from an operation that goes beyond the buffer boundaries in memory. Exploiting this vulnerability allows a local attacker to improperly interact with the CONFIGVMAPSTACK parameter, resulting in a servic...
