A short\nin_len can make pds_fwctl read beyond the allocation.\n\nReject pds RPC buffers that are smaller than struct fwctl_rpc_pds before\nparsing any pds-specific fields."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/fwctl/pds/main.c"],"versions":[{"version":"92c66ee829b99a860a90f62ef16df3e42f92edac","lessThan":"9e3f18883a98420a3b8873c6f894bc57e9b98e41","status":"affected","versionType":"git"},{"version":"92c66ee829b99a860a90f62ef16df3e42f92edac","lessThan":"0d470d36551058e3f728574308b815a80bca710f","status":"affected","versionType":"git"},{"version":"92c66ee829b99a860a90f62ef16df3e42f92edac","lessThan":"e7537735028c3ad4b0bfc02ff8fa2a1a28aa04fe","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/fwctl/pds/main.c"],"versions":[{"version":"6.15","status":"affected"},{"version":"0","lessThan":"6.15","status":"unaffected","versionType":"semver"},{"version":"6.18.34","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.0.11","lessThanOrEqual":"7.0.*","status":"unaffected","versionType":"semver"},{"version":"7.1","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":"6.18.34"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.15","versionEndExcluding":"7.0.11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.15","versionEndExcluding":"7.1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/9e3f18883a98420a3b8873c6f894bc57e9b98e41"},{"url":"https://git.kernel.org/stable/c/0d470d36551058e3f728574308b815a80bca710f"},{"url":"https://git.kernel.org/stable/c/e7537735028c3ad4b0bfc02ff8fa2a1a28aa04fe"}],"title":"fwctl: pds: Validate RPC input size before parsing","x_generator":{"engine":"bippy-1.2.0"}}}}
