CVE-2026-10669 Xtensa MPU `arch_buffer_validate()` integer-overflow lets a user thread bypass syscall pointer validation

On Xtensa SoCs built with CONFIGXTENSAMPU and CONFIGUSERSPACE, archbuffervalidate in arch/xtensa/core/mpu.c — the architecture hook that verifies a user-mode-supplied buffer is accessible to the calling user thread with the requested permission — defaulted its return value to 0 access permitted a...

kernel: cachestat: fix page cache statistics permission checking

In the Linux kernel, the following vulnerability has been resolved: cachestat: fix page cache statistics permission checking When the 'cachestat' system call was added in commit cf264e1329fb "cachestat: implement cachestat syscall", it was meant to be a much more convenient and performant version...

FreeBSD -- Incorrect audit records for ptrace(2) syscall requests

Problem Description: When auditing a system call executed via ptracePTSCREMOTE, the kernel passed the return value of an internal setup function to AUDITSYSCALLEXIT rather than the actual result of the executed system call. As a result, committed audit records for system calls which returned an...

GHSA-F2R5-5M7W-P5CX opentelemetry-ebpf-profiler: Unprivileged process can trigger a denial of service on the ebpf-profiler agent

Summary An unprivileged process can easily trigger the processPIDEvents goroutine to be blocked indefinitely, preventing the goroutine from analyzing any new ELF file. The goroutine stays blocked in the openat2 syscall forever and the profiler can no longer work properly, it is a denial of servic...
