CVE-2026-64251

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

Description A use-after-free issue exists in the pwrseq debugfs seq next() function. The function declares a next variable with free(put device), which triggers put device() when the variable goes out of scope. This causes the seq file framework to receive a pointer whose reference has already been dropped. A use-after-free occurs when the system attempts to access this released memory.

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