CVE-2022-48978

In the Linux kernel, the following vulnerability has been resolved: HID: core: fix shift-out-of-bounds in hid_report_raw_event Syzbot reported shift-out-of-bounds in hid_report_raw_event. microsoft 0003:045E:07DA.0001: hid_field_extract() called with n (128) > 32!

Fix this by adding a check on the size of the integer (unsigned n) in snto32(). To add support for n greater than 32 bits, set n to 32, if n is greater than 32.

Tipo 'int', lo que genera un error de desplazamiento fuera de los l\u00edmites. Solucione este problema agregando una verificaci\u00f3n del tama\u00f1o del entero (n sin signo) en snto32(). Para agregar compatibilidad con n mayor que 32 bits, configure n en 32, si n es mayor que 32."}], "lastModified": "2024-10-25T18:46:23.317", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "216EAACF-C9C3-4743-AC2C-A93410590082", "versionEndExcluding": "4.9.336", "versionStartIncluding": "2.6.20"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "FB3E1F82-01A3-456E-9C83-D567B9A75815", "versionEndExcluding": "4.14.302", "versionStartIncluding": "4.10"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "1185B8E3-712E-4BFB-BD01-78D47F7EF1F2", "versionEndExcluding": "4.19.269", "versionStartIncluding": "4.15"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "8C752145-904B-474A-A7F2-E9F29353B0FE", "versionEndExcluding": "5.4.227", "versionStartIncluding": "4.20"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "7318B597-DFFD-4BBC-A947-539D6E30D82A", "versionEndExcluding": "5.10.159", "versionStartIncluding": "5.5"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "90897BD1-104D-4CFF-94F5-29F9041217FB", "versionEndExcluding": "5.15.83", "versionStartIncluding": "5.11"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "389392A7-81C4-4C26-884B-8C7CF0F53DA4", "versionEndExcluding": "6.0.13", "versionStartIncluding": "5.16"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:6.1:rc1:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E7E331DA-1FB0-4DEC-91AC-7DA69D461C11"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:6.1:rc2:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "17F0B248-42CF-4AE6-A469-BB1BAE7F4705"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:6.1:rc3:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E2422816-0C14-4B5E-A1E6-A9D776E5C49B"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:6.1:rc4:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "1C6E00FE-5FB9-4D20-A1A1-5A32128F9B76"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:6.1:rc5:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "35B26BE4-43A6-4A36-A7F6-5B3F572D9186"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:6.1:rc6:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "3FFFB0B3-930D-408A-91E2-BAE0C2715D80"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:6.1:rc7:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "8535320E-A0DB-4277-800E-D0CE5BBA59E8"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:6.1:rc8:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "21718AA4-4056-40F2-968E-BDAA465A7872"}], "operator": "OR"}]}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67"}
