CVE-2026-45253 Missing validation in ptrace(PT_SC_REMOTE)

ptracePTSCREMOTE failed to properly validate parameters for the syscall2 and syscall2 meta-system calls. As a result, a user with the ability to debug a process may trigger arbitrary code execution in the kernel, even if the target process has no special privileges. The missing validation allows ...

CVE-2026-43619

Rsync version 3.4.2 and prior contain symlink race condition vulnerabilities in path-based system calls including chmod, lchown, utimes, rename, unlink, mkdir, symlink, mknod, link, rmdir, and lstat that allow local attackers to redirect operations to files outside the exported rsync module...

CVE-2026-22167 GPU DDK - Cache resident PM buffers writable by other GPU requestors, leading to arbitrary write to physical memory

Software installed and run as a non-privileged user may conduct improper GPU system calls to force GPU to write to arbitrary physical memory pages. Under certain circumstances this exploit could be used to corrupt data pages not allocated by the GPU driver but memory pages in use by the kernel an...

CVE-2026-22167

CVE-2026-22167 concerns a GPU DDK vulnerability where cache-resident PM buffers can be written by other GPU requestors. The issue allows software running as a non-privileged user to issue improper GPU system calls, forcing the GPU to write to arbitrary physical memory pages. Under certain conditi...

Imagination Graphics DDK 缓冲区错误漏洞

Imagination Graphics DDK is a suite of GPU driver tools from Imagination UK. The Imagination Graphics DDK suffers from a buffer error vulnerability that arises from software run by an unprivileged user that may execute improper GPU system calls to force the GPU to write to arbitrary physical memo...

GHSA-VJGJ-42F6-7997 netfoil's optional seccomp sandboxing was not applied

Summary The optional flag --filter-system-calls was not applied even if specified. Details This is a defense in depth feature to apply additional seccomp filters after the binary has started. The example config also sandboxes the binary with systemd. Impact Reduced sandboxing of the netfoil binar...
