CVE-2026-68356

In the Linux kernel, the following vulnerability has been resolved: watchdog: airoha: Prevent division by zero when clock frequency is zero clkgetrate can return 0 when the clock provider is not properly configured or the clock is unmanaged. The driver uses wdtfreq as a divisor directly in...

CVE-2026-68089

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...

GHSA-9RJG-X2P2-H68H API Platform Core: Relation IRIs are not type-checked: a related resource can be denormalised as the wrong resource type (type confusion)

Summary The API Platform serializer's AbstractItemNormalizer does not validate the resource type returned when resolving relation IRIs, allowing type confusion where a resource of an unintended type can be silently assigned to a relation property. Impact An attacker who can submit write requests...
