A binary\ncarrying more than one PT_INTERP runs the case again and overwrites both\ninterpreter_name and interpreter. The previous name allocation leaks and\nso does the previous interpreter reference, along with the write denial\nopen_exec() took on it. The denial is never released, so the file stays\nunwritable for as long as the system runs.\n\nAn unprivileged caller reaches this with a crafted binary and repeats it\nat will. binfmt_elf stops at the first PT_INTERP. Do the same here.\n\nThe flaw dates back to the driver's introduction in the pre-git history\ntree introduced in v2.6.11 by 91808d6ebe39 (\"[PATCH] FRV: Add FDPIC ELF\nbinary format driver\")."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/binfmt_elf_fdpic.c"],"versions":[{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"9854538349aaf6fb88ed33b56987954ac1716151","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"3c31397b0a75310217f1f2f3c7bdfd8af67aec4c","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"849a7bd9d266e43a457db5c6b322600f916a2127","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"e4563e07ef5c938d5332c5c44721db976f214bc6","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"21eaf5594a33d16343a011c752624099c30e918f","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"89b9121c3b0162655fc2f190b714ae64f1aa8cae","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"69ecc199880bf7e8d06224c82dc411d18f9285f8","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"3349ef6a366a61d631f6a263d12cea240957719d","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/binfmt_elf_fdpic.c"],"versions":[{"version":"2.6.12","status":"affected"},{"version":"0","lessThan":"2.6.12","status":"unaffected","versionType":"semver"},{"version":"5.10.265","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.216","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.183","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.148","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.101","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.42","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.1.6","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":"2.6.12","versionEndExcluding":"5.10.265"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"5.15.216"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.1.183"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.6.148"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.12.101"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.18.42"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"7.1.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/9854538349aaf6fb88ed33b56987954ac1716151"},{"url":"https://git.kernel.org/stable/c/3c31397b0a75310217f1f2f3c7bdfd8af67aec4c"},{"url":"https://git.kernel.org/stable/c/849a7bd9d266e43a457db5c6b322600f916a2127"},{"url":"https://git.kernel.org/stable/c/e4563e07ef5c938d5332c5c44721db976f214bc6"},{"url":"https://git.kernel.org/stable/c/21eaf5594a33d16343a011c752624099c30e918f"},{"url":"https://git.kernel.org/stable/c/89b9121c3b0162655fc2f190b714ae64f1aa8cae"},{"url":"https://git.kernel.org/stable/c/69ecc199880bf7e8d06224c82dc411d18f9285f8"},{"url":"https://git.kernel.org/stable/c/3349ef6a366a61d631f6a263d12cea240957719d"}],"title":"binfmt_elf_fdpic: only honour the first PT_INTERP","x_generator":{"engine":"bippy-1.2.0"}}}}
