CVE-2026-63940 KVM: SEV: Ignore Port I/O requests of length '0'

In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Ignore Port I/O requests of length '0' Explicitly ignore Port I/O requests of length '0' or count '0', so that setting up the software scratch area and other code doesn't have to worry about underflowing the length, and...

CVE-2026-63940

In the Linux kernel KVM SEV issue, the vulnerability concerns ignoring Port I/O requests of length 0. The fix ensures that Port I/O requests with length 0 (or count 0) are explicitly ignored so that the software scratch area setup and related code won’t underflow the length, and to enable a warni...

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 ...
