"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - net/smc: bound the peer rkey counts in SMC-Rv2 LLC messages On a link whose device has maxrecvsge == 1 there is no shared v2 receive buffer, and...

CVE-2026-80984

A flaw was found in the net/smc component of the Linux kernel. When a link group terminates while a socket is waiting in smcclosestreamwait, a NULL pointer dereference can occur during the SMC-D teardown path. This can lead to a system crash, resulting in a Denial of Service DoS...

CVE-2026-80982

A flaw was found in the Linux kernel's Shared Memory Communications SMC network protocol. A race condition occurs when a network connection is closed while the system is still processing its receive buffer pages. This can lead to a use-after-free vulnerability, where the system attempts to access...

CVE-2026-80985

A flaw was found in the Linux kernel's Server Message Block over Remote Direct Memory Access SMC-Rv2 protocol implementation. The smcllcrmtdeleterkey and smcllcsaveaddlinkrkeys functions incorrectly handle oversized LLC messages, reading beyond the intended message boundaries. This can lead to th...

CVE-2026-80986

A flaw was found in the Linux kernel's SMC-Rv2 network component. A remote attacker could exploit this vulnerability by sending a specially crafted message during an SMC-Rv2 link addition. This can lead to a slab-out-of-bounds write, potentially causing a system crash and resulting in a denial of...

CVE-2026-80983

A flaw was found in the Linux kernel's implementation of the Server Message Block SMB over Remote Direct Memory Access RDMA protocol, specifically within the net/smc component. An error path in the smcswitchconns function, triggered during link failover events, can lead to a socket reference coun...

CVE-2026-80979

A flaw was found in the Linux kernel's Shared Memory Communications SMC component. During connection termination, the SMC component may fail to properly unregister a connection before draining its receive tasklet. This can lead to a use-after-free vulnerability, where a freed memory buffer is...

CVE-2026-80980

A flaw was found in the Linux kernel's SMC Server Message Block over Remote Direct Memory Access protocol implementation. A concurrency issue exists where three connection state flags killed, freed, and outofsync share a single byte in the smcconnection structure without proper locking mechanisms...

CVE-2026-80981

A flaw was found in the Linux kernel's net/smc component. A local attacker could exploit a use-after-free vulnerability in the smcllcsrvaddlink function, where a freed memory region is improperly accessed. This can lead to memory corruption and potentially result in a denial of service DoS...
