CVE-2021-47566

CVE-2021-47566 involves a Linux kernel vulnerability in proc/vmcore where user-space buffers were cleared improperly (memset) instead of using clear_user(), enabling a supervisor write fault on a vmcore copy scenario. The fix = use clear_user() when handling user buffers; SMAP handling is noted i...

CVE-2021-47561

CVE-2021-47561 affects the Linux kernel i2c virtio driver. The issue arises when a timeout occurs: the device can continue operating on buffers the guest has freed, risking data corruption on the I2C bus and potential memory corruption inside the guest. The root cause is improper timeout handling...
