EUVD-2026-108786

In the Linux kernel, the following vulnerability has been resolved: namespace: don't copy an unmounted mount tree maycopytree accepts a mount whose root is an nsfs or pidfs file before it checks whether that mount is mounted. This exception exists for nsfs and pidfs mounts. They are part of no...

CVE-2026-98992

The Linux kernel contains a vulnerability in may_copy_tree() where it fails to stop walking an unmounted mount tree. Specifically, when dealing with nsfs or pidfs mounts that are lazily unmounted but kept alive by a file descriptor, recursive operations using MS_REC or AT_RECURSIVE continue to co...

CVE-2026-98989

The Linux kernel contains a vulnerability where the do_loopback() function fails to properly check for recursive bind mount loops when using the MS_REC flag. Specifically, while it checks the starting dentry, it allows the copying of mount namespace files from other namespaces. This allows an att...

CVE-2026-98982 namespace: don't let a pseudo dentry become the root of a mount

In the Linux kernel, the following vulnerability has been resolved: namespace: don't let a pseudo dentry become the root of a mount dallocpseudo hands out dentries for pipes, sockets and other files that are never anyone's child or parent.

CVE-2026-98982

The Linux kernel contains a vulnerability where a pseudo dentry (e.g., for pipes or sockets) can be improperly used as the root of a mount. Specifically, d_alloc_pseudo() provides dentries with the DCACHE_NORCU flag, which are freed immediately by dentry_free() because they are not expected to be...

SUSE CVE-2026-19630

In a BIND resolver, inbound DNS protocol messages with a particular structure will result in additional processing, with no limit imposed by BIND. A DNS message with a maliciously large number of such structures will cause BIND to consume disproportionate amounts of CPU time and memory during...

SUSE CVE-2026-94300

Replaying GSS-TSIG signed UDP messages can result in memory corruption in "named". An attacker who can capture a previously signed UDP message can replay it while the negotiated TSIG key is still valid. By also sending crafted queries to a zone the attacker controls, the attacker may potentially...
