Unprivileged root via a use-after-free in DRM GEM change_handle (CVE-2026-46215)
Stan Shaw published an article about exploiting UAF in a DRM GEM ioctl. The researcher reallocated freed memory as a pipe_buffer array to set PIPE_BUF_FLAG_CAN_MERGE and perform the Dirty Pipe attack.

Bad Epoll: The bug missed by Mythos
Article by Jaeyoung Chung about exploiting CVE-2026-46242 — a race condition bug in the eventpoll subsystem. Jaeyoung exploited this bug to claim a kernelCTF entry, but the vulnerability also affects Android kernels.

Januscape: Guest-to-Host Escape in KVM/x86
Hyunwoo Kim published an article about a use-after-free vulnerability in the shadow MMU emulation of KVM/x86 (CVE-2026-53359). Both Intel (VMX) and AMD (SVM) code is affected.
The article only covers achieving a kernel crash via this bug, but the vulnerability can also be exploited to escape the guest VM. The author used this bug to pwn a kvmCTF instance.

IonStack part III: Rooting Android 17 with GhostLock
Article about adapting the exploit of CVE-2026-43499 (racy stack use-after-free in the futex implementation) to Android.
The researchers used KernelSnitch, ashmem fops overwriting, pipe_buffer corruption, and other tricks to perform LPE.

SCTPhantom: An 18-Year-Old SCTP ASCONF Transport Use-After-Free
Article about exploiting CVE-2026-64564 in the implementation of the Stream Control Transmission Protocol (SCTP). Authors exploited a UAF in the kmalloc-1k cache to gain root and escape a container.

CROSS-X: Generalized and Stable Cross-Cache Attack on the Linux Kernel
Paper by Dong-ok Kim, Juhyun Song, et al. documenting the steps for executing cross-cache attacks for caches with min_partial >= cpu_partial_slabs.
The paper also describes a fuzzing-based approach of finding target slab objects useful for exploitation.
