Currently, in this scenario the freeze listener\nremains in the freeze_listeners rbtree and in the remote node's freeze\nlistener list, even though the ref for which the listener is registered\nis gone. This could potentially lead to a memory leak due to a refcount\ncycle. Thus, remove the freeze listener in this scenario."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/android/binder/freeze.rs", "drivers/android/binder/node.rs", "drivers/android/binder/process.rs"], "versions": [{"version": "eafedbc7c050c44744fbdf80bdf3315e860b7513", "lessThan": "91b27f8172cdbf265240104772fd042a461a7767", "status": "affected", "versionType": "git"}, {"version": "eafedbc7c050c44744fbdf80bdf3315e860b7513", "lessThan": "0644da3621ddd8e146280675a2a31d1e06634a1d", "status": "affected", "versionType": "git"}, {"version": "eafedbc7c050c44744fbdf80bdf3315e860b7513", "lessThan": "bc4a9828897871ff3e5a1f8a1d346decbf4ee95e", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/android/binder/freeze.rs", "drivers/android/binder/node.rs", "drivers/android/binder/process.rs"], "versions": [{"version": "6.18", "status": "affected"}, {"version": "0", "lessThan": "6.18", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.39", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1.4", "lessThanOrEqual": "7.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2-rc3", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.18", "versionEndExcluding": "6.18.39"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.18", "versionEndExcluding": "7.1.4"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.18", "versionEndExcluding": "7.2-rc3"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/91b27f8172cdbf265240104772fd042a461a7767"}, {"url": "https://git.kernel.org/stable/c/0644da3621ddd8e146280675a2a31d1e06634a1d"}, {"url": "https://git.kernel.org/stable/c/bc4a9828897871ff3e5a1f8a1d346decbf4ee95e"}], "title": "rust_binder: clear freeze listener on node removal", "x_generator": {"engine": "bippy-1.2.0"}}}}
