Title
powerpc/kasan: Limit KASAN thread size increase to 32KB
Summary
In the Linux kernel, the following vulnerability has been resolved: powerpc/kasan: Limit KASAN thread size increase to 32KB KASAN is seen to increase stack usage, to the point that it was reported to lead to stack overflow on some 32-bit machines (see link). To avoid overflows the stack size was doubled for KASAN builds in commit 3e8635fb2e07 ("powerpc/kasan: Force thread size increase with KASAN"). However with a 32KB stack size to begin with, the doubling leads to a 64KB stack, which causes build errors: arch/powerpc/kernel/switch.S:249: Error: operand out of range (0x000000000000fe50 is not between 0xffffffffffff8000 and 0x0000000000007fff) Although the asm could be reworked, in practice a 32KB stack seems sufficient even for KASAN builds - the additional usage seems to be in the 2-3KB range for a 64-bit KASAN build. So only increase the stack for KASAN if the stack size is < 32KB.

Para evitar desbordamientos, el tama\u00f1o de la pila se duplic\u00f3 para las compilaciones de KASAN en el commit 3e8635fb2e07 (\\\"powerpc/kasan: Forzar el aumento del tama\u00f1o del subproceso con KASAN\\\"). Sin embargo, con un tama\u00f1o de pila de 32 KB para empezar, la duplicaci\u00f3n conduce a una pila de 64 KB, lo que provoca errores de compilaci\u00f3n: arch/powerpc/kernel/switch.S:249: Error: operando fuera de rango (0x000000000000fe50 no est\u00e1 entre 0xffffffffffff8000 y 0x00000000000007fff) Aunque el conjunto podr\u00eda modificarse, en la pr\u00e1ctica una pila de 32 KB parece suficiente incluso para compilaciones KASAN; el uso adicional parece estar en el rango de 2 a 3 KB para una compilaci\u00f3n KASAN de 64 bits. Por lo tanto, solo aumente la pila para KASAN si el tama\u00f1o de la pila es \u0026lt;32 KB.\"}],\"affected\":[{\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"affectedData\":[{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"unaffected\",\"programFiles\":[\"arch/powerpc/include/asm/thread_info.h\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"9ccf64e763aca088b0d25c1274af42b1a6a45135\",\"lessThan\":\"f9a4c401bf4c5af3437ad221c0a5880a518068d4\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"b38014874530d3776de75679315e8c1fe04aa89b\",\"lessThan\":\"4cc31fa07445879a13750cb061bb8c2654975fcb\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"58f396513cb1fa4ef91838c78698d458100cc27c\",\"lessThan\":\"b29b16bd836a838b7690f80e37f8376414c74cbe\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"18f14afe281648e31ed35c9ad2fcb724c4838ad9\",\"lessThan\":\"f1acb109505d983779bbb7e20a1ee6244d2b5736\",\"versionType\":\"git\",\"status\":\"affected\"}]},{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"unaffected\",\"programFiles\":[\"arch/powerpc/include/asm/thread_info.h\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"6.1.75\",\"lessThan\":\"6.1.76\",\"versionType\":\"semver\",\"status\":\"affected\"},{\"version\":\"6.6.14\",\"lessThan\":\"6.6.18\",\"versionType\":\"semver\",\"status\":\"affected\"},{\"version\":\"6.7.2\",\"lessThan\":\"6.7.6\",\"versionType\":\"semver\",\"status\":\"affected\"}]}]}],\"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}],\"ssvcV203\":[{\"source\":\"134c704f-9b21-4f2e-91b3-4a467353bcc0\",\"ssvcData\":{\"timestamp\":\"2024-04-03T17:38:18.725321Z\",\"id\":\"CVE-2024-26710\",\"options\":[{\"exploitation\":\"none\"},{\"automatable\":\"no\"},{\"technicalImpact\":\"partial\"}],\"role\":\"CISA Coordinator\",\"version\":\"2.0.3\"}}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-770\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.1.75\",\"versionEndExcluding\":\"6.1.79\",\"matchCriteriaId\":\"E45DC1AD-08BC-4CC1-A959-E47949DF8C4D\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.6.14\",\"versionEndExcluding\":\"6.6.18\",\"matchCriteriaId\":\"D414D75C-C82B-4167-B493-0F5458C4D8FC\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.7.2\",\"versionEndExcluding\":\"6.7.6\",\"matchCriteriaId\":\"B739F4F8-3AC5-4589-83F6-43218BC20877\"}]}]}],\"references\":[{\"url\":\"https://git.kernel.org/stable/c/4cc31fa07445879a13750cb061bb8c2654975fcb\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/b29b16bd836a838b7690f80e37f8376414c74cbe\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/f1acb109505d983779bbb7e20a1ee6244d2b5736\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/f9a4c401bf4c5af3437ad221c0a5880a518068d4\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/4297217bcf1f0948a19c2bacc6b68d92e7778ad9\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/4cc31fa07445879a13750cb061bb8c2654975fcb\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/b29b16bd836a838b7690f80e37f8376414c74cbe\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/f1acb109505d983779bbb7e20a1ee6244d2b5736\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Patch\"]}]}}",
