El c\u00f3digo del mapa de pila se basa en roundup_pow_of_two() para calcular el n\u00famero de dep\u00f3sitos de hash y contiene una verificaci\u00f3n de desbordamiento verificando si el valor resultante es 0. Sin embargo, en arcos de 32 bits, el c\u00f3digo de resumen en s\u00ed puede desbordarse al realizar un desplazamiento hacia la izquierda de 32 bits de un valor largo sin signo, lo cual es un comportamiento indefinido, por lo que no se garantiza que se trunque claramente. Esto fue activado por syzbot en el tipo DEVMAP_HASH, que contiene la misma verificaci\u00f3n, copiada del c\u00f3digo hashtab. La confirmaci\u00f3n en la etiqueta de correcciones en realidad intent\u00f3 solucionar este problema, pero la correcci\u00f3n no tuvo en cuenta la UB, por lo que la correcci\u00f3n solo funciona en CPU donde un desbordamiento resulta en un truncamiento claro a cero, lo cual no est\u00e1 garantizado. Verificar el valor antes de redondear no tiene este problema.\"}],\"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\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"HIGH\",\"baseScore\":7.8,\"baseSeverity\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":5.9}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-119\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionEndExcluding\":\"4.19.311\",\"matchCriteriaId\":\"A6E19FC1-2A3F-4FF8-805C-2864C71553EC\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"4.20\",\"versionEndExcluding\":\"5.4.273\",\"matchCriteriaId\":\"620FD8B7-BF03-43E0-951A-0A58461D4C55\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.5\",\"versionEndExcluding\":\"5.10.214\",\"matchCriteriaId\":\"65987874-467B-4D3B-91D6-68A129B34FB8\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.11\",\"versionEndExcluding\":\"5.15.153\",\"matchCriteriaId\":\"ACB69438-845D-4E3C-B114-3140611F9C0B\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.16\",\"versionEndExcluding\":\"6.1.83\",\"matchCriteriaId\":\"121A07F6-F505-4C47-86BF-9BB6CC7B6C19\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.2\",\"versionEndExcluding\":\"6.6.23\",\"matchCriteriaId\":\"E00814DC-0BA7-431A-9926-80FEB4A96C68\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.7\",\"versionEndExcluding\":\"6.7.11\",\"matchCriteriaId\":\"9B95D3A6-E162-47D5-ABFC-F3FA74FA7CFD\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.8\",\"versionEndExcluding\":\"6.8.2\",\"matchCriteriaId\":\"543A75FF-25B8-4046-A514-1EA8EDD87AB1\"}]}]}],\"references\":[{\"url\":\"https://git.kernel.org/stable/c/0971126c8164abe2004b8536b49690a0d6005b0a\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/15641007df0f0d35fa28742b25c2a7db9dcd6895\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/21e5fa4688e1a4d3db6b72216231b24232f75c1d\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/43f798b9036491fb014b55dd61c4c5c3193267d0\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/7070b274c7866a4c5036f8d54fcaf315c64ac33a\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/7a4b21250bf79eef26543d35bd390448646c536b\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/ca1f06e72dec41ae4f76e7b1a8a97265447b46ae\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/d0e214acc59145ce25113f617311aa79dda39cb3\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/f06899582ccee09bd85d0696290e3eaca9aa042d\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]}]}}"
