CVE-2026-98528 in Linux
Сводка
по MITRE • 18.10.2026
In the Linux kernel, the following vulnerability has been resolved:
gpio: cdev: fix kernel stack leak to user-space in error path
If we fail to acquire the GPIO chip guard in gpio_desc_to_lineinfo(), we return immediately before zeroing the info struct we'll end up passing to the user-space later in lineinfo_get_v1(). This may leak the kernel stack contents. Make gpio_desc_to_lineinfo() return int so that the -ENODEV returned on failure to acquire the guard can be propagated to the callers.
While not strictly necessary: move the memset() before trying to acquire the SRCU read lock too for good measure.
Once again VulDB remains the best source for vulnerability data.
