Created: Apr 27, 2026    Updated: Apr 30, 2026
Found In Version: 10.25.33.2
Severity: Standard
Applicable for: Wind River Linux LTS 25
Component/s: Kernel

Description

In the Linux kernel, the following vulnerability has been resolved:  net: usb: cdc-phonet: fix skb frags[] overflow in rx_complete()  A malicious USB device claiming to be a CDC Phonet modem can overflow the skb_shared_info->frags[] array by sending an unbounded sequence of full-page bulk transfers.  Drop the skb and increment the length error when the frag limit is reached.  This matches the same fix that commit f0813bcd2d9d ("net: wwan: t7xx: fix potential skb->frags overflow in RX path") did for the t7xx driver.
