A memory leak vulnerability in the Linux kernel's USB Pegasus network driver (update_eth_regs_async function) was identified and fixed. The issue occurs when usb_submit_urb() fails during asynchronous register writes, causing allocated resources not to be released. This flaw could lead to denial of service by exhausting system memory. The vulnerability has a medium severity with a CVSS score of 5.5. Multiple Linux kernel versions prior to specific 5.15.x updates are affected. Ubuntu has released patches addressing this and other kernel vulnerabilities, requiring system updates and reboots to apply fixes.
