PT-2026-34931

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw in the WireGuard component occurs because the wg netns pre exit function manually acquires rtnl lock within the .pre exit callback. This can lead to a hung task if another thread...

SUSE CVE-2026-31416

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfnetlinklog: account for netlink header size This is a followup to an old bug fix: NLMSGDONE needs to account for the netlink header size, not just the attribute size. This can result in a WARN splat + drop of the...

SUSE CVE-2026-31420

In the Linux kernel, the following vulnerability has been resolved: bridge: mrp: reject zero test interval to avoid OOM panic brmrpstarttest and brmrpstartintest accept the user-supplied interval value from netlink without validation. When interval is 0, usecstojiffies0 yields 0, causing the...

SUSE CVE-2026-31428

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfnetlinklog: fix uninitialized padding leak in NFULAPAYLOAD buildpacketmessage manually constructs the NFULAPAYLOAD netlink attribute using skbput and skbcopybits, bypassing the standard nlareserve/nlaput helpers. Whi...

CVE-2026-31428

A flaw was found in the Linux kernel's netfilter component. When manually constructing the NFULAPAYLOAD netlink attribute, uninitialized padding bytes are not properly cleared. This oversight allows a local user to access stale heap memory contents through the NFLOG netlink socket, leading to...

CVE-2026-31420

A flaw was found in the Linux kernel's bridge subsystem, specifically within the Multiple Registration Protocol MRP implementation. A local user can exploit this vulnerability by supplying a zero-value test interval through the netlink interface without proper validation. This invalid input cause...

CVE-2026-31428

CVE-2026-31428 — In the Linux kernel, nfnetlink_log’s __build_packet_message() previously built NFULA_PAYLOAD attributes manually via skb_put()/skb_copy_bits(), bypassing nla_reserve()/nla_put(). This caused trailing padding to remain uninitialized, leaking stale heap data to userspace over NFLOG...

CVE-2026-31420

CVE-2026-31420 affects Linux kernel bridge MRP interval handling. Vulerability arises when br_mrp_start_test/br_mrp_start_in_test accept a user-supplied interval from netlink with no validation; if interval is 0, the delay becomes zero and a tight loop can exhaust memory, causing an OOM kernel pa...
