{"id":"AZL-102008","summary":"CVE-2026-90300 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Clear buf on error in __bpf_get_task_stack\n\nBoth bpf_get_task_stack and bpf_get_task_stack_sleepable helpers that\nuse __bpf_get_task_stack have buf defined as ARG_PTR_TO_UNINIT_MEM\nargument and we should initialize the buf on every return path.\n\nAdding missing buf memset for __bpf_get_task_stack fail paths. This\nprovides deterministic buffer contents, which is useful when the buffer\nis used directly as a map key.","modified":"2026-09-18T14:15:26.701774542Z","published":"2026-09-17T17:17:27Z","upstream":["CVE-2026-90300"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90300"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-102008.json"}}],"schema_version":"1.9.0"}
