{"id":"AZL-102504","summary":"CVE-2026-90383 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmisc: sgi-gru: remove interrupt-context page-table walks\n\nThe GRU TLB miss handler walks a process's page tables without holding\npage-table locks or a reference to the mapped page. It also uses a kernel\npage-table accessor on user page tables and supports only PMD-level large\nmappings on x86-64.\n\nRemove the direct walker. Send interrupt faults directly to user polling\nmode so the existing call-OS fallback retries them in process context.\n\nRemove the mmap-lock failure statistic that can no longer be incremented.","modified":"2026-09-18T14:16:32.438809015Z","published":"2026-09-17T17:17:37Z","upstream":["CVE-2026-90383"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90383"}],"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-102504.json"}}],"schema_version":"1.9.0"}
