When the function\nfails to grab the object `xprt`, it simply returns 0, forgetting to\ndecrease the reference count of another object `xps`, which is\nincreased by rpc_sysfs_xprt_kobj_get_xprt_switch(), causing refcount\nleaks. Also, the function forgets to check whether `xps` is valid\nbefore using it, which may result in NULL-dereferencing issues.\n\nFix it by adding proper error handling code when either `xprt` or\n`xps` is NULL."}],"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":"5b7eb78486cd9ac58bfbd6d84ea0fe2d9fead03b","lessThan":"c0434f0e058648649250b8ed6078b66d773de723","status":"affected","versionType":"git"},{"version":"5b7eb78486cd9ac58bfbd6d84ea0fe2d9fead03b","lessThan":"76fbeb1662b1c56514325118a07fba74dc4c79fe","status":"affected","versionType":"git"},{"version":"5b7eb78486cd9ac58bfbd6d84ea0fe2d9fead03b","lessThan":"bfc48f1b0505ffcb03a6d749139b7577d6b81ae0","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":"5.14","status":"affected"},{"version":"0","lessThan":"5.14","status":"unaffected","versionType":"semver"},{"version":"5.15.63","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"5.19.4","lessThanOrEqual":"5.19.*","status":"unaffected","versionType":"semver"},{"version":"6.0","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":"5.14","versionEndExcluding":"5.15.63"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"5.19.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.14","versionEndExcluding":"6.0"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/c0434f0e058648649250b8ed6078b66d773de723"},{"url":"https://git.kernel.org/stable/c/76fbeb1662b1c56514325118a07fba74dc4c79fe"},{"url":"https://git.kernel.org/stable/c/bfc48f1b0505ffcb03a6d749139b7577d6b81ae0"}],"title":"net/sunrpc: fix potential memory leaks in rpc_sysfs_xprt_state_change()","x_generator":{"engine":"bippy-1.2.0"}}}}
