However, the\nSTATMOUNT_MNT_UIDMAP and STATMOUNT_MNT_GIDMAP cases directly set the\nstruct fields instead of using offp. This leaves offp uninitialized,\nleading to a possible uninitialized dereference when *offp is updated.\n\nFix it by assigning offp for UIDMAP and GIDMAP as well, keeping the code\npath consistent."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/namespace.c"],"versions":[{"version":"37c4a9590e1efcae7749682239fc22a330d2d325","lessThan":"acfde9400e611c8d2668f1c70053c4a1d6ecfc36","status":"affected","versionType":"git"},{"version":"37c4a9590e1efcae7749682239fc22a330d2d325","lessThan":"0778ac7df5137d5041783fadfc201f8fd55a1d9b","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/namespace.c"],"versions":[{"version":"6.15","status":"affected"},{"version":"0","lessThan":"6.15","status":"unaffected","versionType":"semver"},{"version":"6.17.10","lessThanOrEqual":"6.17.*","status":"unaffected","versionType":"semver"},{"version":"6.18","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":"6.17.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.15","versionEndExcluding":"6.18"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/acfde9400e611c8d2668f1c70053c4a1d6ecfc36"},{"url":"https://git.kernel.org/stable/c/0778ac7df5137d5041783fadfc201f8fd55a1d9b"}],"title":"fs: Fix uninitialized 'offp' in statmount_string()","x_generator":{"engine":"bippy-1.2.0"}}}}
