CVE-2026-63943

The CVE-2026-63943 entry concerns the Linux kernel driver for the xpad (gamepad) device. It describes an out-of-bounds access in xpadone_process_packet(), which uses urb->actual_length as an index to the share-button byte (data[len-18] or data[len-26]); with len and data[0] under the device’s ...

CVE-2026-63943 Input: xpad - fix out-of-bounds access for Share button

In the Linux kernel, the following vulnerability has been resolved: Input: xpad - fix out-of-bounds access for Share button xpadoneprocesspacket receives len directly from urb-actuallength and uses it to index the share-button byte at datalen - 18 or datalen - 26. Since both len and data0 are und...

CVE-2026-63935

The CVE-2026-63935 entry concerns the Linux kernel IIO ADC driver for the NXP SAR ADC. A division-by-zero occurs in write_raw when a user writes zero or negative values to the sampling_frequency sysfs attribute; the fix adds a validation check to prevent using such values as a divisor. The patch ...

CVE-2026-63933

In the Linux kernel, the following vulnerability has been resolved: iio: gyro: adis16260: fix division by zero in writeraw Add a validation check for the sampling frequency value before using it as a divisor. A user writing zero to the samplingfrequency sysfs attribute triggers a division by zero...

CVE-2026-63933

CVE-2026-63933 affects the Linux kernel IIO gyro driver for the ADIS16260. The root cause is a division-by-zero when writing a zero value to the sampling_frequency sysfs attribute, which occurs during write_raw processing. The vulnerability is resolved by adding a validation check for the samplin...

CVE-2026-63931

The CVE-2026-63931 vulnerability in the Linux kernel’s iio: chemical (scd30) driver was resolved by adding a zero check for val2 before using it as a divisor when setting the sampling_frequency sysfs attribute. Previously, a user writing a zero fractional part to sampling_frequency could trigger ...

CVE-2026-63923

CVE-2026-63923 affects the Linux kernel’s octeontx2-af path, where rvu_mbox_handler_rep_event_notify forwards attacker-controlled event fields (pcifunc) without proper bounds checking. The root cause is lack of validation when translating nested body pcifunc into PF/VF mailbox indices, allowing o...

CVE-2026-63921

CVE-2026-63921 affects the Linux kernel’s IPv6 VTI (ip6: vti) implementation. The root cause is a collision-lookup using dev_net(dev) in vti6_siocdevprivate(), which, after tunnels migrate between namespaces, can cause SIOCCHGTUNNEL to resolve against the wrong netns. This enables a scenario wher...
