CVE-2026-68089

A flaw was found in the Linux kernel's Industrial I/O iio core debugfs component. When the ppos value is non-zero during a call to simplewritetobuffer, the start of the buffer buf may not be properly initialized. This uninitialized data can lead to unpredictable behavior or potential information...

PT-2026-69490

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the iio core component where uninitialized data can occur in debugfs. This happens because when the ppos variable is non-zero, the simple write to buffer function fail...

CVE-2026-68089: Undefined Security Weakness

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-2025-38667: Out-of-bounds Write

In the Linux kernel, the following vulnerability has been resolved: iio: fix potential out-of-bound write The buffer is set to 20 characters. If a caller write more characters, count is truncated to the max available space in "simplewritetobuffer". To protect from OoB access, check that the input...

CVE-2025-38484: Out-of-bounds Write

In the Linux kernel, the following vulnerability has been resolved: iio: backend: fix out-of-bound write The buffer is set to 80 character. If a caller write more characters, count is truncated to the max available space in "simplewritetobuffer". But afterwards a string terminator is written to t...

In the Linux kernel, the following vulnerability has been resolved: wifi: wil6210: debugfs: fix uninitialized variable use in wilwritefilewmi Commit 7a4836560a61 changes simplewritetobuffer with memdupuser but it forgets to change the value to be returned that came from simplewritetobuffer call. ...

CVE-2025-38082: Out-of-bounds Write

In the Linux kernel, the following vulnerability has been resolved: gpio: virtuser: fix potential out-of-bound write If the caller wrote more characters, count is truncated to the max available space in "simplewritetobuffer". Check that the input size does not exceed the buffer size. Write a zero...
