When list_del() is used to remove a node\nfrom the xskb pool list, it doesn't reinitialize the node pointers.\nThis means list_empty() will return false even after the node has been\nremoved, causing xp_free() to incorrectly skip adding the buffer to the\nfree list.\n\nFix this by using list_del_init() instead of list_del() in all fragment\nhandling paths, this ensures the list node is reinitialized after removal,\nallowing the list_empty() to work correctly."},{"lang":"es","value":"En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta:\n\nxsk: Corrige la eliminación de nodos de fragmento para prevenir una fuga de búfer\n\nDespués del commit b692bf9a7543 ('xsk: Elimina xdp_buff_xsk::xskb_list_node'), el campo list_node se reutiliza tanto para la lista de la piscina xskb como para la lista de búferes libres, esto causa una fuga de búfer como se describe a continuación.\n\nxp_free() comprueba si un búfer ya está en la lista de libres usando list_empty(&xskb->list_node). Cuando se usa list_del() para eliminar un nodo de la lista de la piscina xskb, no reinicializa los punteros del nodo. Esto significa que list_empty() devolverá falso incluso después de que el nodo haya sido eliminado, causando que xp_free() omita incorrectamente añadir el búfer a la lista de libres.\n\nSoluciona esto usando list_del_init() en lugar de list_del() en todas las rutas de manejo de fragmentos, esto asegura que el nodo de la lista se reinicialice después de la eliminación, permitiendo que list_empty() funcione correctamente."}],"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:H/I:H/A:H","baseScore":7.8,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":5.9}]},"weaknesses":[{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-787"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.13.1","versionEndExcluding":"6.18.17","matchCriteriaId":"40E7536C-DA22-4B7D-9953-0343B4D9A3E6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.19","versionEndExcluding":"6.19.7","matchCriteriaId":"69245D10-0B71-485E-80C3-A64F077004D3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.13:-:*:*:*:*:*:*","matchCriteriaId":"5A3F9505-6B98-4269-8B81-127E55A1BF00"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:7.0:rc1:*:*:*:*:*:*","matchCriteriaId":"F253B622-8837-4245-BCE5-A7BF8FC76A16"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:7.0:rc2:*:*:*:*:*:*","matchCriteriaId":"4AE85AD8-4641-4E7C-A2F4-305E2CD9EE64"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:7.0:rc3:*:*:*:*:*:*","matchCriteriaId":"F666C8D8-6538-46D4-B318-87610DE64C34"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:7.0:rc4:*:*:*:*:*:*","matchCriteriaId":"02259FDA-961B-47BC-AE7F-93D7EC6E90C2"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:7.0:rc5:*:*:*:*:*:*","matchCriteriaId":"58A9FEFF-C040-420D-8F0A-BFDAAA1DF258"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:7.0:rc6:*:*:*:*:*:*","matchCriteriaId":"1D2315C0-D46F-4F85-9754-F9E5E11374A6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:7.0:rc7:*:*:*:*:*:*","matchCriteriaId":"512EE3A8-A590-4501-9A94-5D4B268D6138"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/2a9ea988465ece5b6896b1bdc144170a64e84c35","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/5172adf9efb8298a52f4dcdc3f98d4d9d1e06a6d","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/60abb0ac11dccd6b98fd9182bc5f85b621688861","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/645c6d8376ad4913cbffe0e0c2cca0c4febbe596","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/b38cbd4af5034635cff109e08788c63f956f3a69","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]}]}}]}
