However, the\ncode is assuming the DAMON context wouldn't have schemes at all, and\ntherefore creates and adds new schemes.  As a result, the code doesn't\nwork as intended for online schemes tuning and could have more than\nexpected memory footprint.

En este caso, se supone que la interfaz sysfs de DAMON actualiza, elimina o agrega esquemas para reflejar los archivos sysfs. Sin embargo, el código asume que el contexto DAMON no tendría esquemas en absoluto y, por lo tanto, crea y agrega nuevos esquemas. Como resultado, el código no funciona como se esperaba para el ajuste de esquemas en línea y podría tener una huella de memoria mayor a la esperada. Todos los esquemas están en el contexto DAMON, por lo que no pierde memoria. Elimine la suposición incorrecta (el contexto DAMON no tendría esquemas) en 'damon_sysfs_set_schemes()' para corregir el error."}],"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":"NVD-CWE-noinfo"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"6.0.12","matchCriteriaId":"188DA84C-697A-4F85-A7D6-7318514A07EB"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.1:rc1:*:*:*:*:*:*","matchCriteriaId":"E7E331DA-1FB0-4DEC-91AC-7DA69D461C11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.1:rc2:*:*:*:*:*:*","matchCriteriaId":"17F0B248-42CF-4AE6-A469-BB1BAE7F4705"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.1:rc3:*:*:*:*:*:*","matchCriteriaId":"E2422816-0C14-4B5E-A1E6-A9D776E5C49B"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.1:rc4:*:*:*:*:*:*","matchCriteriaId":"1C6E00FE-5FB9-4D20-A1A1-5A32128F9B76"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.1:rc5:*:*:*:*:*:*","matchCriteriaId":"35B26BE4-43A6-4A36-A7F6-5B3F572D9186"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.1:rc6:*:*:*:*:*:*","matchCriteriaId":"3FFFB0B3-930D-408A-91E2-BAE0C2715D80"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.1:rc7:*:*:*:*:*:*","matchCriteriaId":"8535320E-A0DB-4277-800E-D0CE5BBA59E8"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/95bc35f9bee5220dad4e8567654ab3288a181639","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/f98d1f2a36ad7ab48fb4cf73ca14e7b19482fd4d","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]}]}}]}
