{"id":"AZL-97194","summary":"CVE-2026-74724 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nipvs: avoid out-of-bounds write in ip_vs_nat_icmp\n\nSashiko warns that local attacker can modify the packet\nwhile it is processed by IPVS. Some places read the\nIP ihl field multiple times which can cause out-of-bounds\naccess. One such place is ip_vs_nat_icmp where we\ncan write after the validated area.\n\nFix it by providing ciph argument just like it is done for\nIPv6 and use ciph-\u003elen as offset to the embedded transport\nheader.\n\nModify some IPv4 header checks by reading the ihl field\nonly once.","modified":"2026-08-31T05:26:27Z","published":"2026-08-22T16:16:47Z","upstream":["CVE-2026-74724"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74724"}],"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-97194.json"}}],"schema_version":"1.9.0"}
