CVE detail

CVE-2025-38229

In the Linux kernel, the following vulnerability has been resolved: media: cxusb: no longer judge rbuf when the write fails syzbot reported a uninit-value in cxusb_i2c_xfer. [1] Only when the write operation of usb_bulk_msg() in dvb_usb_generic_rw() succeeds and rlen is greater than 0, the read operation of usb_bulk_msg() will be executed to read rlen bytes of data from the dvb device into the rbuf. In this case, although rlen is 1, the write operation failed which resulted in the dvb read operation not being executed, and ultimately variable i was not initialized.

External lookup

Potential internet exposure

Potential exposure only — not proof of vulnerability.Shodan results indicate potentially internet-exposed products, not confirmed vulnerable systems. They do not confirm that any returned system is vulnerable to CVE-2025-38229.

Product-level CPE searches intentionally omit version fields and NVD version-range or configuration certainty. Verify the exact product version and configuration independently.

Sign-in required. Shodan requires you to sign in to run these filter searches.

How this vector reads

CVSS 3.1 base metrics decoded below. This explanation does not recalculate or change the NVD score.

Attack Vector (AV): Local. The attacker needs local access to the vulnerable system.
Attack Complexity (AC): Low. No special conditions beyond the attacker-controlled steps are required.
Privileges Required (PR): Low. The attacker needs basic user-level privileges.
User Interaction (UI): None. Exploitation does not require another user to act.
Scope (S): Unchanged. Impacts remain within the vulnerable security authority.
Confidentiality Impact (C): None. There is no direct impact to this security property.
Integrity Impact (I): None. There is no direct impact to this security property.
Availability Impact (A): High. There is a total or serious impact to this security property.
