A vulnerability in the Linux kernel's unshare system call was resolved. The issue involved dropping active namespace references that were never taken, leading to reference count inconsistencies. This could cause namespaces the caller lives in to no longer be listed by listns(). The problem occurred when set_cred_ucounts() failed during ksys_unshare(), causing improper reference decrementing. The fix involved properly freeing nsproxy structures that were prepared but never installed. Join the discussion | GCVE Database | 10/23/2026, 15:31:33 UTC Added: 10/23/2026, 18:43:27 UTC |
