{"id":"AZL-109097","summary":"CVE-2026-98605 affecting package kernel 6.6.157.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/bridge: samsung-dsim: fix TE GPIO lifetime for host attach\n\nWhen the Exynos DSI driver was generalized into samsung-dsim, the TE\nGPIO acquisition was switched from gpiod_get_optional() to\ndevm_gpiod_get_optional() while keeping the matching gpiod_put() calls.\nThat combination is wrong for a managed descriptor.\n\nHowever, dropping the puts and keeping the managed get is also wrong:\nsamsung_dsim_register_te_irq() runs from the DSI host attach callback,\nand host detach/reattach can happen without destroying the device that\nowns the managed action. A second attach would then request the GPIO\nagain without having released it.\n\nSwitch back to a non-managed gpiod_get_optional() and keep the explicit\ngpiod_put() on the request_irq() error path and in\nsamsung_dsim_unregister_te_irq().\n\n[Luca: remove unnecessary comment]","modified":"2026-10-19T14:16:31.438668920Z","published":"2026-10-18T16:17:13Z","upstream":["CVE-2026-98605"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98605"}],"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-109097.json"}}],"schema_version":"1.9.0"}
