{"id":"AZL-73406","summary":"CVE-2025-68759 affecting package kernel for versions less than 6.6.121.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rtl818x: Fix potential memory leaks in rtl8180_init_rx_ring()\n\nIn rtl8180_init_rx_ring(), memory is allocated for skb packets and DMA\nallocations in a loop. When an allocation fails, the previously\nsuccessful allocations are not freed on exit.\n\nFix that by jumping to err_free_rings label on error, which calls\nrtl8180_free_rx_ring() to free the allocations. Remove the free of\nrx_ring in rtl8180_init_rx_ring() error path, and set the freed\npriv-\u003erx_buf entry to null, to avoid double free.","modified":"2026-04-21T04:33:53.087580Z","published":"2026-01-05T10:15:57Z","upstream":["CVE-2025-68759"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68759"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.121.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-73406.json"}}],"schema_version":"1.7.5"}
