Several of\nthese buffers are never dealloced.  Some of them can be deallocated\nright after GSP-RM is initialized, but the rest need to stay until the\ndriver unloads.\n\nAlso futher bullet-proof these objects by poisoning the buffer and\nclearing the nvkm_gsp_mem object when it is deallocated.  Poisoning\nthe buffer should trigger an error (or crash) from GSP-RM if it tries\nto access the buffer after we've deallocated it, because we were wrong\nabout when it is safe to deallocate.\n\nFinally, change the mem->size field to a size_t because that's the same\ntype that dma_alloc_coherent expects."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpu/drm/nouveau/include/nvkm/subdev/gsp.h","drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c"],"versions":[{"version":"176fdcbddfd288408ce8571c1760ad618d962096","lessThan":"6190d4c08897d748dd25f0b78267a90aa1694e15","status":"affected","versionType":"git"},{"version":"176fdcbddfd288408ce8571c1760ad618d962096","lessThan":"042b5f83841fbf7ce39474412db3b5e4765a7ea7","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/gpu/drm/nouveau/include/nvkm/subdev/gsp.h","drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c"],"versions":[{"version":"6.7","status":"affected"},{"version":"0","lessThan":"6.7","status":"unaffected","versionType":"semver"},{"version":"6.7.6","lessThanOrEqual":"6.7.*","status":"unaffected","versionType":"semver"},{"version":"6.8","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":"6.7","versionEndExcluding":"6.7.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"6.8"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/6190d4c08897d748dd25f0b78267a90aa1694e15"},{"url":"https://git.kernel.org/stable/c/042b5f83841fbf7ce39474412db3b5e4765a7ea7"}],"title":"drm/nouveau: fix several DMA buffer leaks","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-26912","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-05-28T19:48:15.385423Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-06-04T17:48:54.580Z"}},{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T00:21:05.852Z"},"title":"CVE Program Container","references":[{"url":"https://git.kernel.org/stable/c/6190d4c08897d748dd25f0b78267a90aa1694e15","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/042b5f83841fbf7ce39474412db3b5e4765a7ea7","tags":["x_transferred"]}]}]}}
