In the Linux kernel, the following vulnerability has been resolved: nfc: llcp: Fix list corruption / refcount desync in nfcllcprecvdm nfcllcprecvdm handles DMNOBOUND/DMREJ for a socket that is still linked on local-connectingsockets: it looks the socket up with nfcllcpconnectingsockget, sets...

SUSE CVE-2026-98577

In the Linux kernel, the following vulnerability has been resolved: nfc: llcp: fix WKS SAP hijacking via prefix match in nfcllcpwkssap nfcllcpwkssap compares only servicenamelen bytes, so a short servicename like "u" matches longer WKS strings like "urn:nfc:sn:snep". Fix by requiring exact length...

CVE-2026-98482

A flaw was found in the Linux kernel's Near Field Communication NFC subsystem. The Logical Link Control Protocol LLCP implementation does not verify the length of incoming network packets before reading sequence information. An attacker within NFC radio range could exploit this by transmitting...

CVE-2026-98581

A flaw was found in the Linux kernel's Near Field Communication NFC Logical Link Control Protocol LLCP implementation. When handling specific disconnection packets, the kernel fails to properly lock and unlink sockets before updating their state, leading to internal socket list corruption. A loca...

CVE-2026-98580

A flaw was found in the Linux kernel's Near Field Communication NFC Logical Link Control Protocol LLCP implementation. A race condition occurs during concurrent socket release and connection accept operations due to improper lock synchronization. A local attacker could exploit this flaw to cause ...

CVE-2026-98577

A flaw was found in the Linux kernel's Near Field Communication NFC subsystem. In the Logical Link Control Protocol LLCP implementation, the kernel validates service names using only the length of the provided name instead of verifying an exact match. A local attacker could exploit this flaw by...
