The check for `label->str != NULL` is removed because\n`label->str` can never be NULL if `label` is not NULL.\n\nThis fixes the issue where the label name was being printed as `(efault)`\nwhen dumping the sysfs GPIO file when `label == NULL`."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpio/gpiolib.c"],"versions":[{"version":"a86d27693066a34a29be86f394bbad847b2d1749","lessThan":"9ee4b907d7a5d7a53b4ff7727c371ff3d44ccbbb","status":"affected","versionType":"git"},{"version":"a86d27693066a34a29be86f394bbad847b2d1749","lessThan":"7b99b5ab885993bff010ebcd93be5e511c56e28a","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/gpio/gpiolib.c"],"versions":[{"version":"6.9","status":"affected"},{"version":"0","lessThan":"6.9","status":"unaffected","versionType":"semver"},{"version":"6.11.3","lessThanOrEqual":"6.11.*","status":"unaffected","versionType":"semver"},{"version":"6.12","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":"6.9","versionEndExcluding":"6.11.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.9","versionEndExcluding":"6.12"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/9ee4b907d7a5d7a53b4ff7727c371ff3d44ccbbb"},{"url":"https://git.kernel.org/stable/c/7b99b5ab885993bff010ebcd93be5e511c56e28a"}],"title":"gpiolib: Fix potential NULL pointer dereference in gpiod_get_label()","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-49941","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-10-22T13:37:44.721753Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-10-22T13:38:50.518Z"}}]}}
