{"id":"AZL-70361","summary":"CVE-2022-50167 affecting package kernel 5.15.200.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: fix potential 32-bit overflow when accessing ARRAY map element\n\nIf BPF array map is bigger than 4GB, element pointer calculation can\noverflow because both index and elem_size are u32. Fix this everywhere\nby forcing 64-bit multiplication. Extract this formula into separate\nsmall helper and use it consistently in various places.\n\nSpeculative-preventing formula utilizing index_mask trick is left as is,\nbut explicit u64 casts are added in both places.","modified":"2026-04-01T05:21:44.386877Z","published":"2025-06-18T11:15:47Z","upstream":["CVE-2022-50167"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-50167"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"5.15.200.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-70361.json"}}],"schema_version":"1.7.5"}
