{"id":"AZL-10858","summary":"CVE-2022-39188 affecting package kernel for versions less than 5.15.67.1-4","details":"An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs.","modified":"2026-04-01T05:06:29.798817Z","published":"2022-09-02T05:15:07Z","upstream":["CVE-2022-39188"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-39188"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.15.67.1-4"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-10858.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
