When the device is eventually unbound, mana_remove() is invoked\na second time. Without a NULL check, it dereferences gc->dev with\ngc == NULL, causing a kernel panic.\n\nAdd an early return if gdma_context or driver_data is NULL so the second\ninvocation is harmless. Move the dev = gc->dev assignment after the\nguard so it cannot dereference NULL.","affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"635096a86edb067d55a1e04b4a918f5c6dac0c51"},{"fixed":"a1ddfd2c0b7a48e5239fadd2a24cc4bc2cda90e6"},{"fixed":"bbe5c3c570645a4ceb120979d3ee203a1583d775"},{"fixed":"50271d7ec95144d26808025b508f463780517d3c"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53297.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.18.33"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53297.json"}}],"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/50271d7ec95144d26808025b508f463780517d3c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a1ddfd2c0b7a48e5239fadd2a24cc4bc2cda90e6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bbe5c3c570645a4ceb120979d3ee203a1583d775"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53297.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53297"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53297.json"}}
