A device response shorter than that expectation can therefore\nbe read beyond the skb payload.\n\nRecord -EMSGSIZE for a short response, complete the waiter, and return\nthe stored status from the command path. This also prevents callers from\nconsuming stale response bytes as a successful reply.","state":0,"publishedAt":"2026-10-18T15:49:22.58+00:00","modifiedAt":"2026-10-19T09:26:20.947+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/net/wireless/ath/ath9k/wmi.c\",\n                        \"drivers/net/wireless/ath/ath9k/wmi.h\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"fb9987d0f748c983bb795a86f47522313f701a08\",\n                            \"lessThan\": \"03ef61d05aa26022327f971b790f07e6bf6e35d6\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"fb9987d0f748c983bb795a86f47522313f701a08\",\n                            \"lessThan\": \"e0c21130c1c7791ba73b19a3a9ea767c8cd43745\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"fb9987d0f748c983bb795a86f47522313f701a08\",\n                            \"lessThan\": \"a3b0137c855a61371d9cf9993b8bcc33c9798202\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"fb9987d0f748c983bb795a86f47522313f701a08\",\n                            \"lessThan\": \"93ce8ea70451e800601bc9444aa33043de15d67b\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/net/wireless/ath/ath9k/wmi.c\",\n                        \"drivers/net/wireless/ath/ath9k/wmi.h\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"2.6.35\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"2.6.35\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.12.113\",\n                            \"lessThanOrEqual\": \"6.12.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.56\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.10\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/03ef61d05aa26022327f971b790f07e6bf6e35d6","https://git.kernel.org/stable/c/e0c21130c1c7791ba73b19a3a9ea767c8cd43745","https://git.kernel.org/stable/c/a3b0137c855a61371d9cf9993b8bcc33c9798202","https://git.kernel.org/stable/c/93ce8ea70451e800601bc9444aa33043de15d67b"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-98828","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-98828","identifiers":["CVE-2026-98828"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
