CVE-2026-53024

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

Description A use-after-free issue exists in the greybus raw component. If a user performs a write operation to the chardev after a disconnect has been initiated, the kernel may panic due to a NULL pointer dereference. This occurs because the disconnect process calls gb connection destroy(), which frees the connection object; subsequently, when gb operation sync() is called during write file operations, it attempts to use the already freed connection. The issue involves the raw write() function and the gb operation sync() function.

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