Calling get_shadow_from_swap_cache() on it\n   will result in an out-of-bounds access to swapper_spaces[].\n\n   Validate the entry with non_swap_entry() before going further.\n\n2) When we find a valid swap entry in the shmem's inode, the shadow\n   entry in the swapcache might not exist yet: swap IO is still in\n   progress and we're before __remove_mapping; swapin, invalidation,\n   or swapoff have removed the shadow from swapcache after we saw the\n   shmem swap entry.\n\n   This will send a NULL to workingset_test_recent(). The latter\n   purely operates on pointer bits, so it won't crash - node 0, memcg\n   ID 0, eviction timestamp 0, etc. are all valid inputs - but it's a\n   bogus test. In theory that could result in a false \"recently\n   evicted\" count.\n\n   Such a false positive wouldn't be the end of the world. But for\n   code clarity and (future) robustness, be explicit about this case.\n\n   Bail on get_shadow_from_swap_cache() returning NULL."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["mm/filemap.c"],"versions":[{"version":"cf264e1329fb0307e044f7675849f9f38b44c11a","lessThan":"b79f9e1ff27c994a4c452235ba09e672ec698e23","status":"affected","versionType":"git"},{"version":"cf264e1329fb0307e044f7675849f9f38b44c11a","lessThan":"d962f6c583458037dc7e529659b2b02b9dd3d94b","status":"affected","versionType":"git"},{"version":"cf264e1329fb0307e044f7675849f9f38b44c11a","lessThan":"24a0e73d544439bb9329fbbafac44299e548a677","status":"affected","versionType":"git"},{"version":"cf264e1329fb0307e044f7675849f9f38b44c11a","lessThan":"d5d39c707a4cf0bcc84680178677b97aa2cb2627","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["mm/filemap.c"],"versions":[{"version":"6.5","status":"affected"},{"version":"0","lessThan":"6.5","status":"unaffected","versionType":"semver"},{"version":"6.6.24","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.7.12","lessThanOrEqual":"6.7.*","status":"unaffected","versionType":"semver"},{"version":"6.8.3","lessThanOrEqual":"6.8.*","status":"unaffected","versionType":"semver"},{"version":"6.9","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":"6.5","versionEndExcluding":"6.6.24"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.5","versionEndExcluding":"6.7.12"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.5","versionEndExcluding":"6.8.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.5","versionEndExcluding":"6.9"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/b79f9e1ff27c994a4c452235ba09e672ec698e23"},{"url":"https://git.kernel.org/stable/c/d962f6c583458037dc7e529659b2b02b9dd3d94b"},{"url":"https://git.kernel.org/stable/c/24a0e73d544439bb9329fbbafac44299e548a677"},{"url":"https://git.kernel.org/stable/c/d5d39c707a4cf0bcc84680178677b97aa2cb2627"}],"title":"mm: cachestat: fix two shmem bugs","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"problemTypes":[{"descriptions":[{"type":"CWE","cweId":"CWE-787","lang":"en","description":"CWE-787 Out-of-bounds Write"}]}],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":5.3,"attackVector":"NETWORK","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"LOW","privilegesRequired":"NONE","confidentialityImpact":"NONE"}},{"other":{"type":"ssvc","content":{"timestamp":"2024-05-17T17:19:03.392959Z","id":"CVE-2024-35797","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-11-12T16:52:46.185Z"}},{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T03:21:47.505Z"},"title":"CVE Program Container","references":[{"url":"https://git.kernel.org/stable/c/b79f9e1ff27c994a4c452235ba09e672ec698e23","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/d962f6c583458037dc7e529659b2b02b9dd3d94b","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/24a0e73d544439bb9329fbbafac44299e548a677","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/d5d39c707a4cf0bcc84680178677b97aa2cb2627","tags":["x_transferred"]}]}]}}
