SUSE CVE-2019-15791

In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, shiftfsbtrfsioctlfdreplace installs an fd referencing a file from the lower filesystem without taking an additional reference to that file. After the btrfs ioctl completes this fd is closed, whi...

SUSE CVE-2019-15794

Overlayfs in the Linux kernel and shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, both replace vma-vmfile in their mmap handlers. On error the original value is not restored, and the reference is put for the file to which vmfile points. On...

SUSE CVE-2020-16119

Use-after-free vulnerability in the Linux kernel exploitable by a local attacker due to reuse of a DCCP socket with an attached dccpshctxccid object as a listener after being released. Fixed in Ubuntu Linux kernel 5.4.0-51.56, 5.3.0-68.63, 4.15.0-121.123, 4.4.0-193.224, 3.13.0.182.191 and...

A vulnerability was found in Linux Kernel. It has been classified as critical. This affects the function devlinkparamset/devlinkparamget of the file net/core/devlink.c of the component IPsec. The manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The...

UBUNTU-CVE-2022-3563

A vulnerability classified as problematic has been found in Linux Kernel. Affected is the function read50controllercapcomplete of the file tools/mgmt-tester.c of the component BlueZ. The manipulation of the argument caplen leads to null pointer dereference. It is recommended to apply a patch to f...

CVE-2022-39188

An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition unmapmappingrange versus munmap, a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VMPFNMAP VMAs...

UBUNTU-CVE-2022-3078

UBUNTU-CVE-2022-25265

In the Linux kernel through 5.16.10, certain binary files may have the exec-all attribute if they were built in approximately 2003 e.g., with GCC 3.2.2 and Linux kernel 2.4.20. This can cause execution of bytes located in supposedly non-executable regions of a file...

Exploit for Improper Input Validation in Linux Linux_Kernel

This is a PoC exploit for CVE-2021-3490, a Linux kernel vulnerability. The exploit targets the eBPF subsystem and leverages a bug in the verifier to gain arbitrary read and write access to kernel memory. The exploit is designed to work on Ubuntu 20.04.02 and 20.10 Groovy Gorilla kernels 5.8.0-25....
