{"id":"AZL-102489","summary":"CVE-2026-93144 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Reject writes through untrusted BTF pointers\n\ncheck_ptr_to_btf_access() lets program-type btf_struct_access callbacks\nvalidate writes before the default BTF access path rejects non-read\naccesses. That bypasses the read-only policy for untrusted BTF pointers\ncreated by helpers such as bpf_rdonly_cast().\n\nReject non-read accesses through PTR_UNTRUSTED BTF pointers at the\ncommon entry point, before the callback branch to handle all cases.","modified":"2026-09-18T14:16:33.488975656Z","published":"2026-09-17T17:18:09Z","upstream":["CVE-2026-93144"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93144"}],"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-102489.json"}}],"schema_version":"1.9.0"}
