CVE-2026-72063

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

Description An issue exists in the Tegra GPIO implementation where tegra gpio direction input() and tegra gpio direction output() functions perform redundant calls to pinctrl gpio direction input() and pinctrl gpio direction output(). Because the Tegra pinmux operations do not provide a gpio set direction hook, these additional calls do not perform any useful operation but still enter the pinctrl core and acquire the pctldev->mutex. If shared GPIO users invoke the direction path while holding a per-line spinlock, the system may sleep in an atomic context, leading to a sleep-in-atomic warning.

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