{"id":"AZL-110677","summary":"CVE-2026-98911 affecting package kernel 6.6.157.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndpaa2-switch: fix the error path in dpaa2_switch_rx()\n\nIn case of an error in dpaa2_switch_rx(), the dpaa2_switch_free_fd()\nfunction is called in order to free the FD. This is incorrect since the\ndpaa2_switch_free_fd() is intended to be used on Tx frame descriptors,\nmeaning that it expects in the software annotation area of the FD data\nto find a valid skb pointer on which to call dev_kfree_skb().\n\nFix this by extracting the dma_unmap_page() from\ndpaa2_switch_build_linear_skb() directly into the dpaa2_switch_rx()\nfunction. This allows us to directly use free_pages() in case of an\nerror before an SKB was created and kfree_skb() afterwards.","modified":"2026-10-30T05:35:37Z","published":"2026-10-23T12:18:25Z","upstream":["CVE-2026-98911"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98911"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-110677.json"}}],"schema_version":"1.9.2"}
