CVE-2023-4611 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-02-27 7 High
A use-after-free flaw was found in mm/mempolicy.c in the memory management subsystem in the Linux Kernel. This issue is caused by a race between mbind() and VMA-locked page fault, and may allow a local attacker to crash the system or lead to a kernel information leak.
CVE-2023-4155 3 Fedoraproject, Linux, Redhat 7 Fedora, Linux Kernel, Enterprise Linux and 4 more 2025-02-27 5.3 Medium
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 times, they can trigger a stack overflow and cause a denial of service or potentially guest-to-host escape in kernel configurations without stack guard pages (`CONFIG_VMAP_STACK`).
CVE-2023-2163 2 Linux, Redhat 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more 2025-02-27 10 Critical
Incorrect verifier pruning in BPF in Linux Kernel >=5.4 leads to unsafe code paths being incorrectly marked as safe, resulting in arbitrary read/write in kernel memory, lateral privilege escalation, and container escape.
CVE-2023-5158 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-02-27 6.5 Medium
A flaw was found in vringh_kiov_advance 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.
CVE-2023-1192 2 Linux, Redhat 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more 2025-02-27 6.5 Medium
A use-after-free flaw was found in smb2_is_status_io_timeout() in CIFS in the Linux Kernel. After CIFS transfers response data to a system call, there are still local variable points to the memory region, and if the system call frees it faster than CIFS uses it, CIFS will access a free memory region, leading to a denial of service.
CVE-2023-1193 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-02-27 6.5 Medium
A use-after-free flaw was found in setup_async_work in the KSMBD implementation of the in-kernel samba server and CIFS in the Linux kernel. This issue could allow an attacker to crash the system by accessing freed work.

NVIDIA GPU Driver for Windows and Linux contains a vulnerability in the kernel mode layer, where an unprivileged regular user can cause a NULL-pointer dereference, which may lead to denial of service.
CVE-2023-31022 8 Canonical, Citrix, Linux and 5 more 9 Ubuntu Linux, Hypervisor, Linux Kernel and 6 more 2025-02-27 5.5 Medium
NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode layer, where a NULL-pointer dereference may lead to denial of service.
CVE-2023-1476 2 Linux, Redhat 6 Linux Kernel, Enterprise Linux, Enterprise Linux Eus and 3 more 2025-02-27 7 High
A use-after-free flaw was found in the Linux kernel’s mm/mremap memory address space accounting source code. This issue occurs due to a race condition between rmap walk and mremap, allowing a local user to crash the system or potentially escalate their privileges on the system.
CVE-2023-6039 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-02-27 5.5 Medium
A use-after-free flaw was found in lan78xx_disconnect in drivers/net/usb/lan78xx.c in the network sub-component, net/usb/lan78xx in the Linux Kernel. This flaw allows a local attacker to crash the system when the LAN78XX USB device detaches.
CVE-2023-1513 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2025-02-25 3.3 Low
A flaw was found in KVM. When calling the KVM_GET_DEBUGREGS ioctl, on 32-bit systems, there might be some uninitialized portions of the kvm_debugregs structure that could be copied to userspace, causing an information leak.
CVE-2021-3923 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2025-02-24 2.3 Low
A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a privileged local account can leak kernel stack information when issuing commands to the /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it can be further used to defeat existing kernel protection mechanisms.
CVE-2023-1076 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-02-24 5.5 Medium
A flaw was found in the Linux Kernel. The tun/tap sockets have their socket UID hardcoded to 0 due to a type confusion in their initialization function. While it will be often correct, as tuntap devices require CAP_NET_ADMIN, it may not always be the case, e.g., a non-root user only having that capability. This would make tun/tap sockets being incorrectly treated in filtering/routing decisions, possibly bypassing network filters.
CVE-2023-1075 2 Linux, Redhat 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more 2025-02-24 3.3 Low
A flaw was found in the Linux Kernel. The tls_is_tx_ready() incorrectly checks for list emptiness, potentially accessing a type confused entry to the list_head, leaking the last byte of the confused field that overlaps with rec->tx_ready.
CVE-2023-1079 2 Linux, Redhat 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more 2025-02-19 6.8 Medium
A flaw was found in the Linux kernel. A use-after-free may be triggered in asus_kbd_backlight_set when plugging/disconnecting in a malicious USB device, which advertises itself as an Asus device. Similarly to the previous known CVE-2023-25012, but in asus devices, the work_struct may be scheduled by the LED controller while the device is disconnecting, triggering a use-after-free on the struct asus_kbd_leds *led structure. A malicious USB device may exploit the issue to cause memory corruption with controlled data.
CVE-2023-1637 2 Linux, Redhat 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more 2025-02-19 5.5 Medium
A flaw that boot CPU could be vulnerable for the speculative execution behavior kind of attacks in the Linux kernel X86 CPU Power management options functionality was found in the way user resuming CPU from suspend-to-RAM. A local user could use this flaw to potentially get unauthorized access to some memory of the CPU similar to the speculative execution behavior kind of attacks.
CVE-2023-0179 4 Canonical, Fedoraproject, Linux and 1 more 15 Ubuntu Linux, Fedora, Linux Kernel and 12 more 2025-02-19 7.8 High
A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to the root user via arbitrary code execution.
CVE-2023-1652 2 Linux, Redhat 3 Linux Kernel, Enterprise Linux, Rhel E4s 2025-02-18 7.1 High
A use-after-free flaw was found in nfsd4_ssc_setup_dul in fs/nfsd/nfs4proc.c in the NFS filesystem in the Linux Kernel. This issue could allow a local attacker to crash the system or it may lead to a kernel information leak problem.
CVE-2022-42432 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-02-14 4.4 Medium
This vulnerability allows local attackers to disclose sensitive information on affected installations of the Linux Kernel 6.0-rc2. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the nft_osf_eval function. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the kernel. Was ZDI-CAN-18540.
CVE-2022-4744 2 Linux, Redhat 3 Linux Kernel, Enterprise Linux, Rhel Eus 2025-02-14 7.8 High
A double-free flaw was found in the Linux kernel’s TUN/TAP device driver functionality in how a user registers the device when the register_netdevice function fails (NETDEV_REGISTER notifier). This flaw allows a local user to crash or potentially escalate their privileges on the system.
