{"id":"AZL-85845","summary":"CVE-2026-43153 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nxfs: remove xfs_attr_leaf_hasname\n\nThe calling convention of xfs_attr_leaf_hasname() is problematic, because\nit returns a NULL buffer when xfs_attr3_leaf_read fails, a valid buffer\nwhen xfs_attr3_leaf_lookup_int returns -ENOATTR or -EEXIST, and a\nnon-NULL buffer pointer for an already released buffer when\nxfs_attr3_leaf_lookup_int fails with other error values.\n\nFix this by simply open coding xfs_attr_leaf_hasname in the callers, so\nthat the buffer release code is done by each caller of\nxfs_attr3_leaf_read.","modified":"2026-08-31T05:26:27Z","published":"2026-05-06T12:16:33Z","upstream":["CVE-2026-43153"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43153"}],"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-85845.json"}}],"schema_version":"1.9.0"}
