If sk is an IPv4 socket,\nbut the connect function is called with an IPv6 address,\nthe function calipso_sock_setattr() is triggered.\nInside this function, the following code is executed:\n\nsk_fullsock(__sk) ? inet_sk(__sk)->pinet6 : NULL;\n\nSince sk is an IPv4 socket, pinet6 is NULL, leading to a\nnull pointer dereference.\n\nThis patch fixes the issue by checking if inet6_sk(sk)\nreturns a NULL pointer before accessing pinet6."},{"lang":"es","value":"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: netlabel: Se corrige la excepción de puntero nulo causada por CALIPSO en sockets IPv4. Al llamar a netlbl_conn_setattr(), se utiliza addr->sa_family para determinar el comportamiento de la función. Si sk es un socket IPv4, pero se llama a la función connect con una dirección IPv6, se activa la función calipso_sock_setattr(). Dentro de esta función, se ejecuta el siguiente código: sk_fullsock(__sk) ? inet_sk(__sk)->pinet6 : NULL; Dado que sk es un socket IPv4, pinet6 es NULL, lo que provoca una desreferencia de puntero nulo. Este parche corrige el problema comprobando si inet6_sk(sk) devuelve un puntero nulo antes de acceder a pinet6."}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","baseScore":5.5,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":3.6},{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","baseScore":5.5,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":3.6}]},"weaknesses":[{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-476"}]},{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","description":[{"lang":"en","value":"CWE-476"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.8","versionEndExcluding":"5.4.292","matchCriteriaId":"32BA1759-052A-44B8-BE23-8F8840600FA6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"5.10.236","matchCriteriaId":"1DF46FB0-9163-4ABE-8CCA-32A497D4715B"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.11","versionEndExcluding":"5.15.180","matchCriteriaId":"D19801C8-3D18-405D-9989-E6C9B30255FA"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"6.1.134","matchCriteriaId":"3985DEC3-0437-4177-BC42-314AB575285A"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.6.87","matchCriteriaId":"EFF24260-49B1-4251-9477-C564CFDAD25B"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"6.12.23","matchCriteriaId":"26CAB76D-F00F-43CE-BEAD-7097F8FB1D6C"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.13","versionEndExcluding":"6.13.11","matchCriteriaId":"E7E864B0-8C00-4679-BA55-659B4C9C3AD3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.14","versionEndExcluding":"6.14.2","matchCriteriaId":"FADAE5D8-4808-442C-B218-77B2CE8780A0"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/078aabd567de3d63d37d7673f714e309d369e6e2","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/172a8a996a337206970467e871dd995ac07640b1","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/1927d0bcd5b81e80971bf6b8eba267508bd1c78b","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/1ad9166cab6a0f5c0b10344a97bdf749ae11dcbf","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/1e38f7a6cdd68377f8a4189b2fbaec14a6dd5152","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/3ba9cf69de50e8abed32b448616c313baa4c5712","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/797e5371cf55463b4530bab3fef5f27f7c6657a8","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/9fe3839588db7519030377b7dee3f165e654f6c5","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/a7e89541d05b98c79a51c0f95df020f8e82b62ed","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00030.html","source":"af854a3a-2127-422b-91ae-364da2661108"},{"url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00045.html","source":"af854a3a-2127-422b-91ae-364da2661108"}]}}]}
