Including for\nthreads that no longer have a VM (and maybe never did, like most kernel\nthreads).\n\nIt's not what this flag was designed for, but it is what it is.\n\nThe ptrace code does check that the uid/gid matches, so you do have to\nbe uid-0 to see kernel thread details, but this means that the\ntraditional \"drop capabilities\" model doesn't make any difference for\nthis all.\n\nMake it all make a *bit* more sense by saying that if you don't have a\nMM pointer, we'll use a cached \"last dumpability\" flag if the thread\never had a MM (it will be zero for kernel threads since it is never\nset), and require a proper CAP_SYS_PTRACE capability to override."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["include/linux/sched.h","kernel/exit.c","kernel/ptrace.c"],"versions":[{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"93d4ba49d18e3d7fb41a9927c2d0cca5e9dfefd6","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"15b828a46f305ae9f05a7c16914b3ce273474205","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"4709234fd1b95136ceb789f639b1e7ea5de1b181","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"8f907d345bae8f4b3f004c5abc56bf2dfb851ea7","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"6e5b51e74a40d377bcd3081dd33fbaa0e1aa7e3d","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"2a93a4fac7b6051d3be7cd1b015fe7320cd0404d","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"01363cb3fbd0238ffdeb09f53e9039c9edf8a730","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["include/linux/sched.h","kernel/exit.c","kernel/ptrace.c"],"versions":[{"version":"5.10.256","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.207","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.173","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.139","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.89","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.31","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.0.8","lessThanOrEqual":"7.0.*","status":"unaffected","versionType":"semver"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionEndExcluding":"5.10.256"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionEndExcluding":"5.15.207"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionEndExcluding":"6.1.173"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionEndExcluding":"6.6.139"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionEndExcluding":"6.12.89"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionEndExcluding":"6.18.31"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionEndExcluding":"7.0.8"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/93d4ba49d18e3d7fb41a9927c2d0cca5e9dfefd6"},{"url":"https://git.kernel.org/stable/c/15b828a46f305ae9f05a7c16914b3ce273474205"},{"url":"https://git.kernel.org/stable/c/4709234fd1b95136ceb789f639b1e7ea5de1b181"},{"url":"https://git.kernel.org/stable/c/8f907d345bae8f4b3f004c5abc56bf2dfb851ea7"},{"url":"https://git.kernel.org/stable/c/6e5b51e74a40d377bcd3081dd33fbaa0e1aa7e3d"},{"url":"https://git.kernel.org/stable/c/2a93a4fac7b6051d3be7cd1b015fe7320cd0404d"},{"url":"https://git.kernel.org/stable/c/01363cb3fbd0238ffdeb09f53e9039c9edf8a730"}],"title":"ptrace: slightly saner 'get_dumpable()' logic","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"title":"CVE Program Container","references":[{"url":"http://www.openwall.com/lists/oss-security/2026/05/15/9"},{"url":"https://lists.debian.org/debian-lts-announce/2026/05/msg00032.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2026-05-16T12:20:56.774Z"}}]}}
