A null pointer dereference vulnerability was identified and resolved in the Linux kernel's vc_screen component, specifically in the vcs_notifier() function during concurrent vcs_write operations. The issue arises from a race condition where the vc_data pointer may become NULL after re-acquiring a lock, but the code still calls vcs_scr_updated() with this NULL pointer, causing a null pointer dereference. This vulnerability can lead to a denial of service (system crash). Join the discussion | GCVE Database | 07/19/2026, 12:30:22 UTC Added: 07/19/2026, 19:38:21 UTC |
