{"id":"AZL-102882","summary":"CVE-2026-93163 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nhwrng: core - fix rng list on registration error\n\nhwrng_register(rng) does the following:\n\n1. Checks if rng has name and read methods set\n2. Checks if the name already exists\n3. Adds rng to global rng_list\n4. May try to set rng to current_rng\n\nIf step 4 fails, it returns an error. However, it does not remove the\nrng from rng_list, causing a dangling reference which can result in\nuse-after-free if the caller frees rng, since registration failed.\n\nAdd a list_del_init() cleanup step.","modified":"2026-09-18T14:15:36.647746027Z","published":"2026-09-17T17:18:11Z","upstream":["CVE-2026-93163"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93163"}],"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-102882.json"}}],"schema_version":"1.9.0"}
