EUVD-2026-55270

In the Linux kernel, the following vulnerability has been resolved: iio: core: fix uninitialized data in debugfs If ppos is non-zero then simplewritetobuffer will not initialize the start of buf. Non zero values for ppos aren't going to work anyway. Test for them at the start of the function and...

CVE-2026-68089

The CVE-2026-68089 entry concerns the Linux kernel iio core debugfs handling. It documents a vulnerability where uninitialized data could be exposed when *ppos is non-zero, because simple_write_to_buffer() would not initialize buf[]. The fix adds a test for non-zero *ppos at the start of the affe...
