Astra Linux – Vulnerability in libusrsctp

The usrsctp before December 20, 2019, has out-of-bounds reads in sctploadaddressesfrominit...

Astra Linux – Vulnerability in Linux

A race condition in Linux kernel SCTP sockets net/sctp/socket.c before version 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If the sctpdestroysock function is called without using the socknetsk-sctp.addrwqlock lock, an element...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: sctp: Detect and prevent references to a freed transport in sendmsg. sctpsendmsg reuses transports whenever possible by performing a lookup based on the socket endpoint and the message destination address. Then,...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: SCTP: Fixed a kernel-infoleak issue for SCTP sockets. The syzbot reported a kernel-infoleak issue of 4 bytes. After analysis, it turned out that r-idiagexpires was not initialized when inetsctpdiagfill called...

kernel: sctp: fix race between sctp_wait_for_connect and peeloff

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A race condition exists in the sctpwaitforconnect function, where a socket lock is temporarily released and re-acquired. During this brief period, another process can move the SCTP association to a...

kernel: sctp: validate cached peer INIT chunk length in COOKIE_ECHO processing

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A remote attacker could exploit this by sending a specially crafted COOKIEECHO chunk to a listening SCTP server. The server's failure to properly validate the length of a cached peer INIT chunk within...

kernel: sctp: auth: verify auth requirement when auth_chunk is NULL

A flaw was found in the Stream Control Transmission Protocol SCTP authentication mechanism within the Linux kernel. The sctpauthchunkverify function incorrectly processes authentication chunks, leading to authentication requirements being silently bypassed. This can occur under specific condition...

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...

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: 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...

Linux Distros Unpatched Vulnerability : CVE-2026-89479

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - sctp: stop processing a packet once its association is deleted sctpendpointbhrcv looks the association up only when chunk-asoc is NULL, and caches the result in...

Linux Distros Unpatched Vulnerability : CVE-2026-89477

"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - sctp: fix NULL deref on untransmitted RECONF completion sctpprocessstrresetoutreq, sctpprocessstrresetaddstrmout and sctpprocessstrresetresp complete a pending...

Linux Distros Unpatched Vulnerability : CVE-2026-89478

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - sctp: drop a chunk if its transport was removed sctprcv resolves the transport once per packet and leaves it in chunk-transport. The lookup reference, or the on...

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...

DEBIAN-CVE-2026-89477

In the Linux kernel, the following vulnerability has been resolved: sctp: fix NULL deref on untransmitted RECONF completion sctpprocessstrresetoutreq, sctpprocessstrresetaddstrmout and sctpprocessstrresetresp complete a pending stream reconfiguration request by stopping the reconf timer on the...

CVE-2026-89478

In the Linux kernel, the following vulnerability has been resolved: sctp: drop a chunk if its transport was removed sctprcv resolves the transport once per packet and leaves it in chunk-transport. The lookup reference, or the one sctpaddbacklog takes if the socket is owned by userspace, keeps it...
