CVE-2025-38190

Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)

Description: A issue in the Linux kernel has been resolved, related to the Asynchronous Transfer Mode (ATM) protocol. The problem occurs when the copy from iter full() function fails in vcc sendmsg(), causing a socket leak because atm account tx() is not reverted. To fix this, a new function atm return tx() has been introduced to handle the revert operation. The issue is associated with the vcc sendmsg() and atm pop raw() functions, as well as the sk wmem alloc operation in alloc tx().

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
