The RX poll\ntimer reads the RX buffers without the port lock.\n\nSwitch to dmaengine_terminate_sync() and delete the RX timer before\nfreeing the buffers.","modified":"2026-09-05T03:48:34.785683722Z","published":"2026-09-03T08:21:52.539Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80737.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/440915499231e9db1c361aa45bb702e8fd3b4a32"},{"type":"WEB","url":"https://git.kernel.org/stable/c/44bd0ecc3444882d08ecfbc2b2418d2f463d3186"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5974cb66681eac367107b05924744d7e3b49d41c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9f6989e477f03a4721d34bb4b09b17accd40283e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a38fae9d212e2d3ed5e9ec0ef773f8c0a27fb76e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c8c8e895f65fbf71ea6224e27cf8dab91b776e0d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f70c9d4fba46463a5b1c7b3ee9ee3b40c90dac03"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fdfb46c387241b4eddd36d746793764413285913"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80737.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80737"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"ead76f329f777c7301e0a5456a0a1c7a081570bd"},{"fixed":"a38fae9d212e2d3ed5e9ec0ef773f8c0a27fb76e"},{"fixed":"44bd0ecc3444882d08ecfbc2b2418d2f463d3186"},{"fixed":"f70c9d4fba46463a5b1c7b3ee9ee3b40c90dac03"},{"fixed":"c8c8e895f65fbf71ea6224e27cf8dab91b776e0d"},{"fixed":"9f6989e477f03a4721d34bb4b09b17accd40283e"},{"fixed":"5974cb66681eac367107b05924744d7e3b49d41c"},{"fixed":"fdfb46c387241b4eddd36d746793764413285913"},{"fixed":"440915499231e9db1c361aa45bb702e8fd3b4a32"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80737.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.39"},{"fixed":"5.10.267"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.218"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.185"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.154"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.106"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.45"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80737.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
