{"id":"AZL-56240","summary":"CVE-2024-53161 affecting package kernel for versions less than 5.15.176.3-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nEDAC/bluefield: Fix potential integer overflow\n\nThe 64-bit argument for the \"get DIMM info\" SMC call consists of mem_ctrl_idx\nleft-shifted 16 bits and OR-ed with DIMM index.  With mem_ctrl_idx defined as\n32-bits wide the left-shift operation truncates the upper 16 bits of\ninformation during the calculation of the SMC argument.\n\nThe mem_ctrl_idx stack variable must be defined as 64-bits wide to prevent any\npotential integer overflow, i.e. loss of data from upper 16 bits.","modified":"2026-04-01T05:18:50.421779Z","published":"2024-12-24T12:15:24Z","upstream":["CVE-2024-53161"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-53161"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.15.176.3-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-56240.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
