CVE-2017-7518 [HIGH] CWE-250 CVE-2017-7518: A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the tra A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap flag(TF) bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exception(#DB) being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate their privileges inside the guest. Linux

CVE-2022-1652 [HIGH] CWE-416 CVE-2022-1652: Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a concu Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a concurrency use-after-free flaw in the bad_flp_intr function. By executing a specially-crafted program, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system.

CVE-2021-45417 [HIGH] CWE-787 CVE-2021-45417: AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as X AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as XFS extended attributes or tmpfs ACLs), because of a heap-based buffer overflow.

CVE-2020-1749 [HIGH] CWE-319 CVE-2020-1749: A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would allow anyone in between the two endpoints

CVE-2023-43787 [HIGH] CWE-122 CVE-2023-43787: A vulnerability was found in libX11 due to an integer overflow within the XCreateImage() function. T A vulnerability was found in libX11 due to an integer overflow within the XCreateImage() function.

CVE-2025-26599 [HIGH] CWE-824 CVE-2025-26599: An access to an uninitialized pointer flaw was found in X.Org and Xwayland. The function compCheckRe An access to an uninitialized pointer flaw was found in X.Org and Xwayland. The function compCheckRedirect() may fail if it cannot allocate the backing pixmap. In that case, compRedirectWindow() will return a BadAlloc error without validating the window tree marked just before, which leaves the validated data partly initialized and the use of an unini

CVE-2021-38160 [HIGH] CWE-120 CVE-2021-38160: In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss can be t In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE: the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the length validation was added solely for robustness in

CVE-2024-0409 [HIGH] CWE-787 CVE-2024-0409: A flaw was found in the X.Org server. The cursor code in both Xephyr and Xwayland uses the wrong typ A flaw was found in the X.Org server. The cursor code in both Xephyr and Xwayland uses the wrong type of private at creation. It uses the cursor bits type with the cursor as private, and when initiating the cursor, that overwrites the XSELINUX context.

CVE-2020-25712 [HIGH] CWE-122 CVE-2020-25712: A flaw was found in xorg-x11-server before 1.20.10. A heap-buffer overflow in XkbSetDeviceInfo may l A flaw was found in xorg-x11-server before 1.20.10. A heap-buffer overflow in XkbSetDeviceInfo may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

CVE-2024-0841 [HIGH] CWE-476 CVE-2024-0841: A null pointer dereference flaw was found in the hugetlbfs_fill_super function in the Linux kernel h A null pointer dereference flaw was found in the hugetlbfs_fill_super function in the Linux kernel hugetlbfs (HugeTLB pages) functionality.
