{"id":"AZL-97124","summary":"CVE-2026-74608 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nsmb: client: Fix use-after-free in cifs_try_adding_channels()\n\ncifs_try_adding_channels() takes a temporary reference to an interface\nbefore dropping iface_lock. If cifs_ses_add_channel() fails, it drops\nthat reference and then increments iface-\u003eweight_fulfilled.\n\nA concurrent interface list refresh can remove the list reference while\nchannel creation is in progress. In that case, the failure-path\nkref_put() releases the last reference and frees iface. Updating\nweight_fulfilled afterward then accesses freed memory.\n\nIncrement weight_fulfilled before dropping the temporary reference,\nkeeping iface alive for the final access.","modified":"2026-08-30T05:26:50Z","published":"2026-08-22T16:16:33Z","upstream":["CVE-2026-74608"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74608"}],"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-97124.json"}}],"schema_version":"1.9.0"}
