An improper input validation flaw was found in the eBPF subsystem in the Linux kernel. The issue occurs due to a lack of proper validation of dynamic pointers within user-supplied eBPF programs prior to executing them. This may allow an attacker with CAPBPF privileges to escalate privileges and...
CVE-2023-5158
A flaw was found in vringhkiovadvance in drivers/vhost/vringh.c in the host side of a virtio ring in the Linux Kernel. This issue may result in a denial of service from guest to host via zero length descriptor...
kernel: Intel firmware update for Incorrect default permissions in some memory controller configurations
A flaw was found in the Linux kernel. Some IntelR XeonR processors with Intel® Software Guard Extensions SGX may allow privilege escalation. This issue may allow a privileged user to enable privilege escalation via local access...
kernel: Linux kernel: Denial of Service due to GIC state corruption on NVIDIA T241 platforms
A flaw was found in the Linux kernel. On NVIDIA server platforms utilizing multiple interconnected T241 chips, a local user could trigger a vulnerability in the Generic Interrupt Controller GIC due to incorrect handling of inter-socket data packets. This can corrupt the GIC's internal state,...
SUSE CVE-2023-4155
A flaw was found in KVM AMD Secure Encrypted Virtualization SEV in the Linux kernel. A KVM guest using SEV-ES or SEV-SNP with multiple vCPUs can trigger a double fetch race condition vulnerability and invoke the VMGEXIT handler recursively. If an attacker manages to call the handler multiple time...
kernel: KVM: x86/mmu: race condition in direct_page_fault()
A flaw was found in the Linux kernel in the KVM. A race condition in directpagefault allows guest OS users to cause a denial of service host OS crash or host OS memory corruption when nested virtualization and the TDP MMU are enabled...
CVE-2023-3773
A flaw was found in the Linux kernel’s IP framework for transforming packets XFRM subsystem. This issue may allow a malicious user with CAPNETADMIN privileges to cause a 4 byte out-of-bounds read of XFRMAMTIMERTHRESH when parsing netlink attributes, leading to potential leakage of sensitive heap...
CVE-2023-32248
A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the handling of SMB2TREECONNECT and SMB2QUERYINFO commands. The issue results from the lack of proper validation of a pointer prior to accessing it. An attacker can leverage this...
AZL-27637 CVE-2023-33951 affecting package hyperv-daemons for versions less than 5.15.158.1-1
A race condition vulnerability was found in the vmwgfx driver in the Linux kernel. The flaw exists within the handling of GEM objects. The issue results from improper locking when performing operations on an object. This flaw allows a local privileged user to disclose information in the context o...
CVE-2023-32258
A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the processing of SMB2LOGOFF and SMB2CLOSE commands. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this...
CVE-2023-32247
A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the handling of SMB2SESSIONSETUP commands. The issue results from the lack of control of resource consumption. An attacker can leverage this vulnerability to create a...
CVE-2023-32252
A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the handling of SMB2LOGOFF commands. The issue results from the lack of proper validation of a pointer prior to accessing it. An attacker can leverage this vulnerability to creat...
kernel: uninitialized registers on stack in nft_do_chain can cause kernel pointer leakage to UM
A flaw was found in the Linux kernel in net/netfilter/nftablescore.c:nftdochain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker...
CVE-2023-32250
A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the processing of SMB2SESSIONSETUP commands.
