CVE-2026-10671

CVE-2026-10671 affects Zephyr kernel: the userspace verifier for k_pipe_init used K_SYSCALL_OBJ(), allowing an unprivileged thread with access to a k_pipe object to re-init a live pipe. This re-initialization clears the ring buffer and wait queues without accounting for current blockers, leaving ...

CVE-2026-10671 User thread can re-initialize an in-use `k_pipe`, corrupting kernel wait queues (`CONFIG_USERSPACE`)

In Zephyr's kernel pipe implementation, the userspace syscall verifier zvrfykpipeinit in kernel/pipe.c used KSYSCALLOBJ which requires the kernel object to already be initialized instead of KSYSCALLOBJNEVERINIT which rejects an already-initialized object. As a result, on CONFIGUSERSPACE builds an...

Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2026-002692)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-002692 advisory. fs/pipe.c in the Linux kernel before 4.5 does not limit the amount of unread data in pipes, which allows local users to cause a denial of service memory consumption ...

Linux Distros Unpatched Vulnerability : CVE-2022-0847

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A flaw was found in the way the flags member of the new pipe buffer structure was lacking proper initialization in copypagetoiterpipe and pushpipe functions in...

CVE-2013-3952

The fillpipeinfo function in bsd/kern/syspipe.c in the XNU kernel in Apple Mac OS X 10.8.x allows local users to defeat the KASLR protection mechanism via the PROCPIDFDPIPEINFO option to the procinfo system call for a kernel pipe handle...

SUSE CVE-2016-0774

The 1 piperead and 2 pipewrite implementations in fs/pipe.c in a certain Linux kernel backport in the linux package before 3.2.73-2+deb7u3 on Debian wheezy and the kernel package before 3.10.0-229.26.2 on Red Hat Enterprise Linux RHEL 7.1 do not properly consider the side effects of failed...

kernel: pipe buffer state corruption after unsuccessful atomic read from pipe

It was found that the fix for CVE-2015-1805 incorrectly kept buffer offset and buffer length in sync on a failed atomic read, potentially resulting in a pipe buffer state corruption. A local, unprivileged user could use this flaw to crash the system or leak kernel memory to user space...
