CVE-2026-63938

The vulnerability CVE-2026-63938 affects the Linux kernel KVM SEV path, specifically PSC processing. The issue arises when validating PSC requests: the PSC buffer must be checked against the effective size of the scratch area, which may be smaller than the maximum if a guest supplies a pointer no...

CVE-2026-63937

In the Linux kernel, CVE-2026-63937 pertains to KVM SEV where entries/indices in the guest-accessible PSC Page State Change buffer are now read with READ_ONCE() to defend against TOCTOU bugs. This change targets misbehavior by guests and reduces potential timing-related issues when the buffer is ...

CVE-2026-63934

The CVE-2026-63934 entry describes a Linux kernel vulnerability in iio: gyro: itg3200 where i2c_read writes into the wrong stack location. Specifically, itg3200_read_all_channels() takes __be16 *buf and uses (char *)&buf for i2c_transfer(), which points to a local stack slot rather than the calle...
