{"id":"CVE-2026-99049","summary":"gpio: xilinx: fix runtime PM leak on request error path","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ngpio: xilinx: fix runtime PM leak on request error path\n\npm_runtime_get_sync() leaves the usage counter incremented even when it\nfails, and xgpio_request() returns the error without dropping it.\n\ngpiolib does not call -\u003efree() when -\u003erequest() fails, so xgpio_free(),\nwhich holds the only matching pm_runtime_put(), never runs. The reference\nis leaked and the controller can no longer runtime-suspend, so its clock\nstays enabled.\n\nSwitch to pm_runtime_resume_and_get(), which only increments the usage\ncounter on success.","modified":"2026-11-06T17:27:13.265350090Z","published":"2026-10-23T12:22:26.409Z","related":["SUSE-SU-2026:24550-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/99xxx/CVE-2026-99049.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2fd6ecda5d1f47cffcfadddb35ee49402162c724"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3c7c764a3e933b4b32a847edeb89c8d1930613f4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7fa0e73dc31f4e653918fc002d64909c83f4b020"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a027e0d7765d1531ee39e4dae81951b04f32ba7b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b07b3925f676640103b3d74b93fc401b1c873d13"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f73ee2bd2293f8cc340061c5229395ace71fc2eb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ff82fc3a4a1d417dee1229681cc5285986edb1fa"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/99xxx/CVE-2026-99049.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-99049"},{"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":"26b04774621ed333e8bc56479feb6e31625df58c"},{"fixed":"3c7c764a3e933b4b32a847edeb89c8d1930613f4"},{"fixed":"7fa0e73dc31f4e653918fc002d64909c83f4b020"},{"fixed":"b07b3925f676640103b3d74b93fc401b1c873d13"},{"fixed":"f73ee2bd2293f8cc340061c5229395ace71fc2eb"},{"fixed":"a027e0d7765d1531ee39e4dae81951b04f32ba7b"},{"fixed":"2fd6ecda5d1f47cffcfadddb35ee49402162c724"},{"fixed":"ff82fc3a4a1d417dee1229681cc5285986edb1fa"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-99049.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.12.0"},{"fixed":"5.15.224"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.191"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.160"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.113"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.57"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-99049.json"}}],"schema_version":"1.9.2"}
