CVE-2026-74587

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. During peer restart handling, the system improperly releases a cached ASCONF chunk without clearing its pointer, leading to a use-after-free vulnerability. A remote attacker could exploit this by...

CVE-2026-74586

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. An authenticated remote SCTP peer can trigger a use-after-free vulnerability by adding and then immediately removing a transport within the same ASCONF chunk. This can lead to a system crash, resultin...
