{"apiVersion":"1.0","identifier":"CVE-2026-72413","description":"In the Linux kernel, the following vulnerability has been resolved: sctp: fix err_chunk memory leaks in INIT handling When sctp_verify_init() encounters unrecognized parameters, it allocates an err_chunk to report them. However, this chunk is leaked in several code paths: 1. In sctp_sf_do_5_1B_init(), if security_sctp_assoc_request() fails after sctp_verify_init() has populated err_chunk, the function returns immediately without freeing it. 2. In sctp_sf_do_unexpected_init(), the same leak occurs on the security_sctp_assoc_request() failure path. 3. In sctp_sf_do_unexpected_init(), on the success path after copying unrecognized parameters to the INIT-ACK, the function returns without freeing err_chunk, unlike sctp_sf_do_5_1B_init() which properly frees it. Fix all three leaks by adding sctp_chunk_free(err_chunk) calls before returning in the error paths and on the success path in sctp_sf_do_unexpected_init().","publishedAt":"2026-08-15T06:22:14","lastModifiedAt":"2026-08-17T06:19:08","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72413","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00189,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72413","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72413","en":"https://www.redsauce.net/en/cves/CVE-2026-72413","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72413","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72413","de":"https://www.redsauce.net/de/cves/CVE-2026-72413","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72413","el":"https://www.redsauce.net/el/cves/CVE-2026-72413"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72413"}}
