kernel: sctp: fix auth_hmacs array size in struct sctp_cookie

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. An incorrect array size calculation for the authhmacs field within the sctpcookie structure could lead to a buffer overflow. During the initialization of an SCTP association, if four HMAC identifiers...

kernel: sctp: validate stream count in sctp_process_strreset_inreq()

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. When processing a Stream Reset Incoming Request RESETINREQUEST from a peer, the kernel does not properly validate the stream count. This can lead to an integer overflow when calculating the size for t...

kernel: sctp: diag: reject stale associations in dump_one path

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP diagnostics. When performing a socket diagnostic sockdiag lookup, the system may attempt to access memory related to an SCTP association that has already been freed. This can lead to an out-of-bounds read from...

Linux Distros Unpatched Vulnerability : CVE-2026-89476

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - sctp: fix stream-outcnt underflow on duplicate RECONF responses A cached RECONF chunk may contain more than one request parameter. A duplicate response can...

CVE-2026-89478

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. An authenticated attacker could exploit a timing window during the removal of an SCTP transport. This could lead to the system attempting to read from freed memory, potentially causing a denial of...

CVE-2026-89479

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A remote attacker could send a specially crafted series of SCTP packets, leading to a use-after-free vulnerability. This occurs when the kernel attempts to access memory that has already been...

CVE-2026-89477

A flaw was found in the Stream Control Transmission Protocol SCTP implementation within the Linux kernel. This vulnerability occurs when the kernel attempts to complete a stream reconfiguration request that has not been fully transmitted, leading to a null pointer dereference. An unprivileged loc...

CVE-2026-89476

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A remote attacker could exploit this by sending specially crafted duplicate RECONF responses. This action can cause an underflow in the stream-outcnt counter, potentially leading to unexpected system...
