SUSE CVE-2020-29371

An issue was discovered in romfsdevread in fs/romfs/storage.c in the Linux kernel before 5.8.4. Uninitialized memory leaks to userspace, aka CID-bcf85fcedfdd...

SUSE CVE-2020-35498

A vulnerability was found in openvswitch. A limitation in the implementation of userspace packet parsing can allow a malicious user to send a specially crafted packet causing the resulting megaflow in the kernel to be too wide, potentially causing a denial of service. The highest threat from this...

SUSE CVE-2021-4159

A vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures. Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating som...

SUSE CVE-2021-28972

In drivers/pci/hotplug/rpadlparsysfs.c in the Linux kernel through 5.11.8, the RPA PCI Hotplug driver has a user-tolerable buffer overflow when writing a new device name to the driver from userspace, allowing userspace to write data to the kernel stack frame directly. This occurs because...

SUSE CVE-2022-0850

A vulnerability was found in linux kernel, where an information leak occurs via ext4extentheader to userspace...

Denial Of Service (DoS)

Linux Kernel is vulnerable to Denial Of Service DoS. The vulnerability exists in the i740 driver because the Userspace program could pass any values to the driver through the ioctl interface, which doesn't check the value of pixclock, causing a divide by zero error...

kernel: KVM: cmpxchg_gpte can write to pfns outside the userspace region

A flaw was found in KVM. When updating a guest's page table entry, vmpgoff was improperly used as the offset to get the page's pfn. As vaddr and vmpgoff are controllable by user-mode processes, this flaw allows unprivileged local users on the host to write outside the userspace region and...
