{"id":"AZL-51333","summary":"CVE-2024-49977 affecting package kernel for versions less than 5.15.173.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: stmmac: Fix zero-division error when disabling tc cbs\n\nThe commit b8c43360f6e4 (\"net: stmmac: No need to calculate speed divider\nwhen offload is disabled\") allows the \"port_transmit_rate_kbps\" to be\nset to a value of 0, which is then passed to the \"div_s64\" function when\ntc-cbs is disabled. This leads to a zero-division error.\n\nWhen tc-cbs is disabled, the idleslope, sendslope, and credit values the\ncredit values are not required to be configured. Therefore, adding a return\nstatement after setting the txQ mode to DCB when tc-cbs is disabled would\nprevent a zero-division error.","modified":"2026-04-01T05:17:42.792800Z","published":"2024-10-21T18:15:18Z","upstream":["CVE-2024-49977"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-49977"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.15.173.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-51333.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"}]}
