kernel: nvmet-rdma: handle inline data with a nonzero offset

A flaw was found in the nvmet-rdma component of the Linux kernel. This vulnerability arises from incorrect handling of inline data with a non-zero offset, which can lead to an integer underflow. An attacker could exploit this to cause the system to read beyond its allocated memory, potentially...

kernel: rhashtable: clear stale iter->p on table restart

A flaw was found in the Linux kernel. This vulnerability, known as a use-after-free, occurs in the rhashtable component when the system improperly handles hash table restarts. An attacker could potentially exploit this by causing the system to access memory that has already been released, which m...

kernel: smb: client: validate DFS referral PathConsumed

A flaw was found in the Linux kernel's Server Message Block SMB client. A remote attacker could send a specially crafted SMB response containing a malformed Distributed File System DFS referral. This could cause the PathConsumed value to exceed the search name length, leading to an out-of-bounds...

kernel: net: bridge: stop fast-leave after deleting a port group

A flaw was found in the Linux kernel's network bridge module. When handling multicast fast-leave, a vulnerability exists where the system may attempt to access a port group after it has been deleted. This can occur if multicast-to-unicast was previously enabled and then disabled, leading to a sta...

CVE-2026-87822 t-digest 3.1 through 3.3 Denial of Service via NaN Centroid Means in MergingDigest.fromBytes

t-digest versions 3.1 through 3.3 fail to validate centroid means during deserialization in MergingDigest.fromBytes, allowing attackers to inject NaN values that bypass validation checks. Attackers can craft malicious serialized digests containing NaN centroids that degrade sorting performance fr...

CVE-2026-87822

t-digest versions 3.1 through 3.3 contain a denial-of-service vulnerability in MergingDigest.fromBytes . During deserialization, centroid means are not validated, allowing an attacker to inject NaN values that bypass existing checks. When such a malformed digest is merged, sorting performance deg...

CVE-2026-57159

A flaw was found in PJSIP. An out-of-bounds read and write can occur in the SDP negotiator when the remote payload-type map maintenance feature is enabled. A remote attacker can trigger this via payload-type numbers taken from a remote SDP offer or answer, which are used as an index to access...

CVE-2026-86204
