The ipu7_bus_release() function frees adev->pdata when the\ndevice's reference count drops to zero.\n\nTwo error paths incorrectly call kfree(pdata) after the device teardown\nhas already freed it:\n\n1. When ipu7_mmu_init() fails: put_device() is called, which drops the\n reference count to zero and triggers ipu7_bus_release() ->\n kfree(pdata). The subsequent kfree(pdata) is a double-free.\n\n2. When ipu7_bus_add_device() fails: it calls auxiliary_device_uninit()\n internally, which calls put_device() -> ipu7_bus_release() ->\n kfree(pdata). The subsequent kfree(pdata) is again a double-free.\n\nNote that the kfree(pdata) when ipu7_bus_initialize_device() itself\nfails is correct, because in that case auxiliary_device_init() failed\nand the release function was never set up, so pdata must be freed\nmanually.\n\nAdditionally, the error code was not saved before calling put_device(),\ncausing ERR_CAST() to dereference the already-freed adev pointer when\nconstructing the return value. Fix this by saving the error from\ndev_err_probe() before put_device() and returning ERR_PTR() instead.\n\nRemove the redundant kfree(pdata) calls and fix the use-after-free in\nthe return values of the two affected error paths."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/staging/media/ipu7/ipu7.c"], "versions": [{"version": "b7fe4c0019b12d60ece3e99eeb0ccfd5a1d103e5", "lessThan": "b5ddc7257bee71f5b8cf9083e2b0ac0427e9fbb3", "status": "affected", "versionType": "git"}, {"version": "b7fe4c0019b12d60ece3e99eeb0ccfd5a1d103e5", "lessThan": "837c1f9655421055f751ed34745e820a54a27642", "status": "affected", "versionType": "git"}, {"version": "b7fe4c0019b12d60ece3e99eeb0ccfd5a1d103e5", "lessThan": "d3a9a8cf2d7fd61a2f63df61f6cbc0a9bb007cc0", "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/staging/media/ipu7/ipu7.c"], "versions": [{"version": "6.17", "status": "affected"}, {"version": "0", "lessThan": "6.17", "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-rc1", "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": "6.17", "versionEndExcluding": "6.18.39"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.17", "versionEndExcluding": "7.1.4"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.17", "versionEndExcluding": "7.2-rc1"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/b5ddc7257bee71f5b8cf9083e2b0ac0427e9fbb3"}, {"url": "https://git.kernel.org/stable/c/837c1f9655421055f751ed34745e820a54a27642"}, {"url": "https://git.kernel.org/stable/c/d3a9a8cf2d7fd61a2f63df61f6cbc0a9bb007cc0"}], "title": "staging: media: ipu7: fix double-free and use-after-free in error paths", "x_generator": {"engine": "bippy-1.2.0"}}}}
