Vulnerability from cvelistv5
Published

Severity ?
7.1 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: tools/power/x86/intel-speed-select: Harden daemon pidfile open Avoid symlink-based pidfile clobbering by opening the pidfile with O_NOFOLLOW and validating it with fstat() before locking/writing. The daemon currently uses a fixed pidfile path under /tmp. A local unprivileged user can pre-create a symlink at that path and cause a root-run daemon instance to write into an attacker-chosen file.

once the root OOB service is running, the attacker needs only the pre-planted symlink with no further victim action.\\nS:U - The root daemon\u0027s misdirected open/write affects host filesystem objects within the same OS security authority; this is a local root-assisted file clobber, not a VM escape, container breakout, or IOMMU boundary bypass.\\nC:N - The daemon only writes a short numeric PID string via write() and never reads from the opened descriptor; there is no memory corruption, out-of-bounds read, or other information-disclosure primitive.\\nI:H - A symlink causes the root daemon\u0027s open(O_RDWR|O_CREAT) to follow into an attacker-chosen path, letting root truncate/overwrite the start of protected files (e.g., /etc/passwd, sudoers, unit files) or create new root-owned files in restricted directories.\\nA:H - Overwriting the beginning of critical configuration or authentication files with root privileges can break login, service startup, or ISST OOB management, producing system-wide denial of service beyond a single daemon crash.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"7fd786dfbd2c55ddee3b87f33c82f1c58bdb1dd6\", \"lessThan\": \"905493a6338c82a70da16f86e0a6215db5a3d73d\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"7fd786dfbd2c55ddee3b87f33c82f1c58bdb1dd6\", \"lessThan\": \"db938eb9a3c1317596c28e94413b33426508d51b\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"7fd786dfbd2c55ddee3b87f33c82f1c58bdb1dd6\", \"lessThan\": \"72a07abc6b9046f07a08bba353cad7667bcc9dce\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"7fd786dfbd2c55ddee3b87f33c82f1c58bdb1dd6\", \"lessThan\": \"19ffeb30fdfce63f8d6aca71bcdddb3f69d46278\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"7fd786dfbd2c55ddee3b87f33c82f1c58bdb1dd6\", \"lessThan\": \"e8adac69d1bdf035ef97cc914e845acd4ef08e28\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"7fd786dfbd2c55ddee3b87f33c82f1c58bdb1dd6\", \"lessThan\": \"607af438e6430893a822964c841a1994b33acccc\", \"versionType\": \"git\"}], \"programFiles\": [\"tools/power/x86/intel-speed-select/isst-daemon.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5.18\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"5.18\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"6.1.178\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.145\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.97\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.40\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.1.5\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.1.*\"}, {\"status\": \"unaffected\", \"version\": \"7.2\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"tools/power/x86/intel-speed-select/isst-daemon.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/905493a6338c82a70da16f86e0a6215db5a3d73d\"}, {\"url\": \"https://git.kernel.org/stable/c/db938eb9a3c1317596c28e94413b33426508d51b\"}, {\"url\": \"https://git.kernel.org/stable/c/72a07abc6b9046f07a08bba353cad7667bcc9dce\"}, {\"url\": \"https://git.kernel.org/stable/c/19ffeb30fdfce63f8d6aca71bcdddb3f69d46278\"}, {\"url\": \"https://git.kernel.org/stable/c/e8adac69d1bdf035ef97cc914e845acd4ef08e28\"}, {\"url\": \"https://git.kernel.org/stable/c/607af438e6430893a822964c841a1994b33acccc\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\ntools/power/x86/intel-speed-select: Harden daemon pidfile open\\n\\nAvoid symlink-based pidfile clobbering by opening the pidfile with\\nO_NOFOLLOW and validating it with fstat() before locking/writing.\\n\\nThe daemon currently uses a fixed pidfile path under /tmp.
