CVE-2026-97524

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

Description An issue exists in the mptcp receive path where, under specific error conditions, the system can recursively call the mptcp data ready() function via a state change, leading to an attempt to acquire the data lock again. This recursion loop occurs during subflow reset. The issue involves unneeded processing to check for available data on a dying subflow, including calls to get mapping status(), as well as problems in error reporting and worker scheduling.

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