Linux Kernel - Out-of-bounds Read via Sound Subsystem ioctl Interface
An out-of-bounds access issue was found in the Linux kernel sound subsystem. It could occur when the 'id->name' provided by the user did not end with '\0'. A privileged local user could pass a specially crafted name through ioctl() interface and crash the system or potentially escalate their privileges on the system.

CVE-2022-2962 WRITEUP HIGH WRITEUP
QEMU 4.2.0-7.0.0 - Denial of Service via Tulip DMA Reentrancy
A DMA reentrancy issue was found in the Tulip device emulation in QEMU. When Tulip reads or writes to the rx/tx descriptor or copies the rx/tx frame, it doesn't check whether the destination address is its own MMIO address. This can cause the device to trigger MMIO handlers multiple times, possibly leading to a stack or heap overflow. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition.
