{"id":"AZL-65768","summary":"CVE-2025-38382 affecting package kernel for versions less than 6.6.104.2-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: fix iteration of extrefs during log replay\n\nAt __inode_add_ref() when processing extrefs, if we jump into the next\nlabel we have an undefined value of victim_name.len, since we haven't\ninitialized it before we did the goto. This results in an invalid memory\naccess in the next iteration of the loop since victim_name.len was not\ninitialized to the length of the name of the current extref.\n\nFix this by initializing victim_name.len with the current extref's name\nlength.","modified":"2026-04-01T05:20:38.714514Z","published":"2025-07-25T13:15:27Z","upstream":["CVE-2025-38382"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38382"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.104.2-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-65768.json"}}],"schema_version":"1.7.5"}
