EUVD-2026-103573

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 gpiodesctolineinfo, we return immediately before zeroing the info struct we'll end up passing to the user-space later in...

CVE-2026-98528

The Linux kernel contains a vulnerability in the gpio cdev component where a failure to acquire the GPIO chip guard in gpio_desc_to_lineinfo() causes the function to return prematurely. This results in a kernel stack leak to user-space because the information structure is not zeroed before being ...
