CVE-2026-99128

The Linux kernel contains a vulnerability in the SCTP stack where sctp_inq_pop() accepts chunks with declared lengths shorter than the required four-byte generic header. A remote SCTP peer can trigger a receive softirq lockup by sending a zero-length ASCONF chunk. This is exploitable on kernels c...
