While this allocation failure is\nhandled properly and request is rejected, it results in syzkaller\nreports. Additionally, such request may put undue burden on the\nsystem which will try to free a lot of memory for a bogus request.\n\nFix it by limiting allowed number of slots to 100. This can easily\nbe extended if we see devices that can track more than 100 contacts." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/input/misc/uinput.c" ], "versions": [ { "version": "38e7afe96c7c0ad900824911c61fdb04078033dc", "lessThan": "9c6d189f0c1c59ba9a32326ec82a0b367a3cd47b", "status": "affected", "versionType": "git" }, { "version": "38e7afe96c7c0ad900824911c61fdb04078033dc", "lessThan": "597ff930296c4c8fc6b6a536884d4f1a7187ec70", "status": "affected", "versionType": "git" }, { "version": "38e7afe96c7c0ad900824911c61fdb04078033dc", "lessThan": "51fa08edd80003db700bdaa099385c5900d27f4b", "status": "affected", "versionType": "git" }, { "version": "38e7afe96c7c0ad900824911c61fdb04078033dc", "lessThan": "9719687398dea8a6a12a10321a54dd75eec7ab2d", "status": "affected", "versionType": "git" }, { "version": "38e7afe96c7c0ad900824911c61fdb04078033dc", "lessThan": "61df76619e270a46fd427fbdeb670ad491c42de2", "status": "affected", "versionType": "git" }, { "version": "38e7afe96c7c0ad900824911c61fdb04078033dc", "lessThan": "a4858b00a1ec57043697fb935565fe267f161833", "status": "affected", "versionType": "git" }, { "version": "38e7afe96c7c0ad900824911c61fdb04078033dc", "lessThan": "d76fc0f0b18d49b7e721c9e4975ef4bffde2f3e7", "status": "affected", "versionType": "git" }, { "version": "38e7afe96c7c0ad900824911c61fdb04078033dc", "lessThan": "206f533a0a7c683982af473079c4111f4a0f9f5e", "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/input/misc/uinput.c" ], "versions": [ { "version": "2.6.36", "status": "affected" }, { "version": "0", "lessThan": "2.6.36", "status": "unaffected", "versionType": "semver" }, { "version": "4.19.322", "lessThanOrEqual": "4.19.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.4.284", "lessThanOrEqual": "5.4.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.10.226", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.167", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.110", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.51", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.10.10", "lessThanOrEqual": "6.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.11", "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": "2.6.36", "versionEndExcluding": "4.19.322" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.36", "versionEndExcluding": "5.4.284" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.36", "versionEndExcluding": "5.10.226" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.36", "versionEndExcluding": "5.15.167" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.36", "versionEndExcluding": "6.1.110" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.36", "versionEndExcluding": "6.6.51" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.36", "versionEndExcluding": "6.10.10" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.36", "versionEndExcluding": "6.11" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/9c6d189f0c1c59ba9a32326ec82a0b367a3cd47b" }, { "url": "https://git.kernel.org/stable/c/597ff930296c4c8fc6b6a536884d4f1a7187ec70" }, { "url": "https://git.kernel.org/stable/c/51fa08edd80003db700bdaa099385c5900d27f4b" }, { "url": "https://git.kernel.org/stable/c/9719687398dea8a6a12a10321a54dd75eec7ab2d" }, { "url": "https://git.kernel.org/stable/c/61df76619e270a46fd427fbdeb670ad491c42de2" }, { "url": "https://git.kernel.org/stable/c/a4858b00a1ec57043697fb935565fe267f161833" }, { "url": "https://git.kernel.org/stable/c/d76fc0f0b18d49b7e721c9e4975ef4bffde2f3e7" }, { "url": "https://git.kernel.org/stable/c/206f533a0a7c683982af473079c4111f4a0f9f5e" } ], "title": "Input: uinput -
