{"id":"CVE-2026-68185","summary":"LoongArch: Move jump_label_init() before parse_early_param()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nLoongArch: Move jump_label_init() before parse_early_param()\n\nWhen enabling both CONFIG_MEM_ALLOC_PROFILING=y and\nCONFIG_MEM_ALLOC_PROFILING_ENABLED_BY_DEFAULT=y, then diabling memory\nprofiling by adding the boot parameter 'sysctl.vm.mem_profiling=0' will\ncause the kernel failed to boot.\n\nAfter analysis, this is because jump_label_init() must be called before\nparse_early_param(), the early param handlers may modify static keys by\nstatic_branch_enable/disable().\n\nFix this by moving jump_label_init() to before parse_early_param(). The\nsolution is similar to other architectures.","modified":"2026-08-20T03:31:07.130256016Z","published":"2026-08-10T11:59:57.327Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68185.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/38b025fcdc45bdf5140a5726a1fbb2e694ea047b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4b40e590efb350c54480d7e883f054d3609a94c6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/881e9f3c4e117b100880b1c5de3a0da8e455a78f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ea68d444a658783234a06f05414e41cf93a18fb2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68185.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68185"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"628c3bb40e9a8cefc0a6fde28b7b66bfe46d1dc2"},{"fixed":"4b40e590efb350c54480d7e883f054d3609a94c6"},{"fixed":"38b025fcdc45bdf5140a5726a1fbb2e694ea047b"},{"fixed":"881e9f3c4e117b100880b1c5de3a0da8e455a78f"},{"fixed":"ea68d444a658783234a06f05414e41cf93a18fb2"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-68185.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.19.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-68185.json"}}],"schema_version":"1.9.0"}
