In the Linux kernel, the following vulnerability has been resolved: ovl: don't warn when the mount is completed from another user namespace fsopen records the caller's user namespace in fc-userns and hands back an ordinary file descriptor. Nothing ties the task that calls fsconfigFSCONFIGCMDCREAT...

CVE-2026-74619

This Linux kernel vulnerability affects the overlayfs component. An unprivileged task can trigger a WARN_ON() in ovl_fill_super() by creating a user and mount namespace in a child process, calling fsopen("overlay"), passing the fscontext file descriptor to the parent, and having the parent issue ...

CVE-2026-74617 dibs: initialise dibs->lock in dibs_dev_alloc()

In the Linux kernel, the following vulnerability has been resolved: dibs: initialise dibs-lock in dibsdevalloc dibs-lock is initialised by dibsdevadd, but a dibs device can already take interrupts before that call: ismprobe runs ismdevinit, and hence requestirq, before it calls dibsdevadd. No...

CVE-2026-74618

CVE-2026-74618 affects the Linux kernel 's binfmt_misc filesystem. The root cause is a WARN_ON() in bm_fill_super() that triggers when a binfmt_misc mount is completed from a different user namespace than the one that created the fscontext via fsopen(). Because fsconfig(FSCONFIG_CMD_CREATE) autho...

CVE-2026-74617

CVE-2026-74617 affects the Linux kernel 's dibs device driver. The root cause is that dibs->lock was initialised in dibs_dev_add(), but a dibs device can already receive interrupts before that call: ism_probe() invokes ism_dev_init() (which calls request_irq()) prior to dibs_dev_add(). A GID e...
