{"id":"AZL-91331","summary":"CVE-2026-53297 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: mana: Guard mana_remove against double invocation\n\nIf PM resume fails (e.g., mana_attach() returns an error), mana_probe()\ncalls mana_remove(), which tears down the device and sets\ngd-\u003egdma_context = NULL and gd-\u003edriver_data = NULL.\n\nHowever, a failed resume callback does not automatically unbind the\ndriver. When the device is eventually unbound, mana_remove() is invoked\na second time. Without a NULL check, it dereferences gc-\u003edev with\ngc == NULL, causing a kernel panic.\n\nAdd an early return if gdma_context or driver_data is NULL so the second\ninvocation is harmless. Move the dev = gc-\u003edev assignment after the\nguard so it cannot dereference NULL.","modified":"2026-08-30T05:26:50Z","published":"2026-06-26T20:17:22Z","upstream":["CVE-2026-53297"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53297"}],"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-91331.json"}}],"schema_version":"1.9.0"}
