UBUNTU-CVE-2025-38348: High severity ubuntu/linux vulnerability

Q: What access does an attacker need to trigger this issue?

An attacker needs to present a malicious USB device that impersonates an Intersil p54 Wi-Fi interface and sends an EEPROM readback message with a manipulated length value. The supplied vector indicates physical access, with no privileges or user interaction required.

Q: What is the practical impact of successful exploitation?

The malformed EEPROM length can make the p54 driver copy beyond the end of its EEPROM buffer. The report describes this causing a kernel crash or panic.

Q: What does the available fix change?

The fix stores the expected EEPROM size in the common device context rather than trusting the length returned by the device. This prevents the receive handler from using an attacker-controlled length for the copy.

In the Linux kernel, the following vulnerability has been resolved: wifi: p54: prevent buffer-overflow in p54rxeepromreadback() Robert Morris reported: |If a malicious USB device pretends to be an Intersil p54 wifi |interface and generates an eepromreadback message with a large |eeprom->v1.len, p54rxeepromreadback() will copy data from the |message beyond the end of priv->eeprom. | |static void p54rxeepromreadback(struct p54common priv, | struct skbuff skb) |{ | struct p54hdr hdr = (struct p54hdr ) skb->data; | struct p54eepromlm86 eeprom = (struct p54eepromlm86 ) hdr->data; | | if (priv->fwvar >= 0x509) { | memcpy(priv->eeprom, eeprom->v2.data, | le16tocpu(eeprom->v2.len)); | } else { | memcpy(priv->eeprom, eeprom->v1.data, | le16tocpu(eeprom->v1.len)); | } | [...] The eeprom->v{1,2}.len is set by the driver in p54downloadeeprom(). The device is supposed to provide the same length back to the driver. But yes, it's possible (like shown in the report) to alter the value to something that causes a crash/panic due to overrun. This patch addresses the issue by adding the size to the common device context, so p54rxeepromreadback no longer relies on possibly tampered values... That said, it also checks if the "firmware" altered the value and no longer copies them. The one, small saving grace is: Before the driver tries to read the eeprom, it needs to upload >a< firmware. the vendor firmware has a proprietary license and as a reason, it is not present on most distributions by default.

Frequently Asked Questions

What access does an attacker need to trigger this issue?

An attacker needs to present a malicious USB device that impersonates an Intersil p54 Wi-Fi interface and sends an EEPROM readback message with a manipulated length value. The supplied vector indicates physical access, with no privileges or user interaction required.

What is the practical impact of successful exploitation?

The malformed EEPROM length can make the p54 driver copy beyond the end of its EEPROM buffer. The report describes this causing a kernel crash or panic.

What does the available fix change?

The fix stores the expected EEPROM size in the common device context rather than trusting the length returned by the device. This prevents the receive handler from using an attacker-controlled length for the copy.
