Por lo tanto, la comprobación de que no sea NULL no es suficiente para determinar si la IRQ es válida. Compruebe que la IRQ sea mayor que cero para asegurarse de que sea válida. No hay ningún problema en el momento de la prueba, pero en el momento de la ejecución, el usuario puede invocar .set_channels, lo que da como resultado la siguiente cadena de llamadas. am65_cpsw_set_channels() am65_cpsw_nuss_update_tx_rx_chns() am65_cpsw_nuss_remove_tx_chns() am65_cpsw_nuss_init_tx_chns() En este punto, si am65_cpsw_nuss_init_tx_chns() falla debido a k3_udma_glue_tx_get_irq(), tx_chn->irq se establecerá en un valor negativo. Luego, en los .set_channels posteriores con un mayor conteo de canales, intentaremos liberar una IRQ no válida en am65_cpsw_nuss_remove_tx_chns(), lo que generará una advertencia del kernel. El problema está presente en el commit original que introdujo este controlador, aunque allí, am65_cpsw_nuss_update_tx_rx_chns() existía como am65_cpsw_nuss_update_tx_chns()."}],"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}]},"weaknesses":[{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-476"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.7","versionEndExcluding":"5.10.235","matchCriteriaId":"3D5CC9A1-5315-4625-AE8A-2D18D09E897D"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.11","versionEndExcluding":"5.15.179","matchCriteriaId":"C708062C-4E1B-465F-AE6D-C09C46400875"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"6.1.129","matchCriteriaId":"2DA5009C-C9B9-4A1D-9B96-78427E8F232C"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.6.76","matchCriteriaId":"A6D70701-9CB6-4222-A957-00A419878993"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"6.12.13","matchCriteriaId":"2897389C-A8C3-4D69-90F2-E701B3D66373"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.13","versionEndExcluding":"6.13.2","matchCriteriaId":"6D4116B1-1BFD-4F23-BA84-169CC05FC5A3"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/321990fdf4f1bb64e818c7140688bf33d129e48d","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/4395a44acb15850e492dd1de9ec4b6479d96bc80","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/8448c87b3af68bebca21e3136913f7f77e363515","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/88fd5db8c0073bd91d18391feb5741aeb0a2b475","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/8aae91ae1c65782a169ec070e023d4d269e5d6e6","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/aea5cca681d268f794fa2385f9ec26a5cce025cd","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/ed8c0300f302338c36edb06bca99051e5be6fb2f","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00028.html","source":"af854a3a-2127-422b-91ae-364da2661108"},{"url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00030.html","source":"af854a3a-2127-422b-91ae-364da2661108"}]}}]}
