The ->length is the length\nof the buffer.  The ->bytesused is how many bytes we have copied thus\nfar.  When the condition is reversed that means the result of the\nsubtraction is always negative but since it's unsigned then the result\nis a very high positive value.  That means the overflow check is never\ntrue.\n\nAdditionally, the ->bytesused doesn't actually work for this purpose\nbecause we're not writing to \"buf->mem + buf->bytesused\".  Instead, the\nmath to calculate the destination where we are writing is a bit\ninvolved.  You calculate the number of full lines already written,\nmultiply by two, skip a line if necessary so that we start on an odd\nnumbered line, and add the offset into the line.\n\nTo fix this buffer overflow, just take the actual destination where we\nare writing, if the offset is already out of bounds print an error and\nreturn.  Otherwise, write up to buf->length bytes."},{"lang":"es","value":"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: medios: stk1160: revisión de los límites fijos en stk1160_copy_video() La resta en esta condición se invierte. La ->longitud es la longitud del búfer. El ->byteused es cuántos bytes hemos copiado hasta ahora. Cuando la condición se invierte, eso significa que el resultado de la resta siempre es negativo, pero como no tiene signo, el resultado es un valor positivo muy alto. Eso significa que la verificación de desbordamiento nunca es cierta. Además, ->bytesused en realidad no funciona para este propósito porque no estamos escribiendo en \"buf->mem + buf->bytesused\". En cambio, las matemáticas para calcular el destino donde estamos escribiendo son un poco complicadas. Calcula el número de líneas completas ya escritas, multiplica por dos, omite una línea si es necesario para comenzar en una línea impar y agrega el desplazamiento a la línea. Para solucionar este desbordamiento del búfer, simplemente tome el destino real donde estamos escribiendo, si el desplazamiento ya está fuera de los límites imprima un error y regrese. De lo contrario, escriba hasta buf->bytes de longitud."}],"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:N/A:H","baseScore":7.1,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":5.2}]},"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":"3.7","versionEndExcluding":"4.19.316","matchCriteriaId":"C3E0E450-224E-4D44-B428-69760573832B"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.20","versionEndExcluding":"5.4.278","matchCriteriaId":"7FDBF235-DA18-49A1-8690-6C7272FD0701"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"5.10.219","matchCriteriaId":"E9063AF3-D593-43B7-810D-58B87F82F9F9"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.11","versionEndExcluding":"5.15.161","matchCriteriaId":"31130639-53FE-4726-8986-434EE2528CB2"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"6.1.93","matchCriteriaId":"EEFB78EE-F990-4197-BF1C-156760A55667"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.6.33","matchCriteriaId":"FCE796DF-3B50-4DC6-BAE5-95271068FC9E"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"6.9.4","matchCriteriaId":"991B9791-966A-4D18-9E8D-A8AB128E5627"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/7532bcec0797adfa08791301c3bcae14141db3bd","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/a08492832cc4cacc24e0612f483c86ca899b9261","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/a16775828aaed1c54ff4e6fe83e8e4d5c6a50cb7","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/b504518a397059e1d55c521ba0ea2b545a6c4b52","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/d410017a7181cb55e4a5c810b32b75e4416c6808","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/ecf4ddc3aee8ade504c4d36b7b4053ce6093e200","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/f6a392266276730bea893b55d12940e32a25f56a","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/faa4364bef2ec0060de381ff028d1d836600a381","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/7532bcec0797adfa08791301c3bcae14141db3bd","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/a08492832cc4cacc24e0612f483c86ca899b9261","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/a16775828aaed1c54ff4e6fe83e8e4d5c6a50cb7","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/b504518a397059e1d55c521ba0ea2b545a6c4b52","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/d410017a7181cb55e4a5c810b32b75e4416c6808","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/ecf4ddc3aee8ade504c4d36b7b4053ce6093e200","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/f6a392266276730bea893b55d12940e32a25f56a","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/faa4364bef2ec0060de381ff028d1d836600a381","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://lists.debian.org/debian-lts-announce/2024/06/msg00020.html","source":"af854a3a-2127-422b-91ae-364da2661108"}]}}]}
