While some\nfields are manually populated, critical fields like srcaddr, bc_xps,\nand flags contain uninitialized stack garbage.\n\nThis can lead to:\n1. Kernel panic when xs_setup_xprt() dereferences garbage srcaddr\n2. Information leak if srcaddr points to sensitive stack data\n3. Unpredictable behavior if flags has random bits set\n\nThe fix is to zero-initialize the structure to ensure all unused\nfields are NULL/0, preventing the transport setup code from acting\non garbage data."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/sunrpc/sysfs.c"],"versions":[{"version":"df210d9b0951d714c1668c511ca5c8ff38cf6916","lessThan":"933654508b2bc36e2c3c086c0365e2403fb2141f","status":"affected","versionType":"git"},{"version":"df210d9b0951d714c1668c511ca5c8ff38cf6916","lessThan":"7d3ce3bd23c062a7c1c6d372d1b08e48b9e17cc3","status":"affected","versionType":"git"},{"version":"df210d9b0951d714c1668c511ca5c8ff38cf6916","lessThan":"17d90b68c3a3d7d7e95b49e1fe9381a723f637a8","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["net/sunrpc/sysfs.c"],"versions":[{"version":"6.15","status":"affected"},{"version":"0","lessThan":"6.15","status":"unaffected","versionType":"semver"},{"version":"6.18.40","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.1.5","lessThanOrEqual":"7.1.*","status":"unaffected","versionType":"semver"},{"version":"7.2","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":"6.15","versionEndExcluding":"6.18.40"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.15","versionEndExcluding":"7.1.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.15","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/933654508b2bc36e2c3c086c0365e2403fb2141f"},{"url":"https://git.kernel.org/stable/c/7d3ce3bd23c062a7c1c6d372d1b08e48b9e17cc3"},{"url":"https://git.kernel.org/stable/c/17d90b68c3a3d7d7e95b49e1fe9381a723f637a8"}],"title":"sunrpc: fix uninitialized xprt_create_args structure","x_generator":{"engine":"bippy-1.2.0"}}}}
