Linux Distros Unpatched Vulnerability : CVE-2026-43210

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - tracing: ring-buffer: Fix to check event length before using Check the event length before adding it for accessing next index in rbreaddatabuffer. Since this...

CVE-2026-43210

A flaw was found in the Linux kernel's tracing ring-buffer subsystem. This vulnerability occurs in the rbreaddatabuffer function, which fails to validate the length of an event before using it to determine the next memory address. If an event's length is corrupted, this can lead to an invalid...

CVE-2026-43272

CVE-2026-43272 concerns the Linux kernel ring-buffer component. The root cause is an uninitialized pointer in rb_meta_validate_events(), which can be dereferenced during a reader-page validation failure, potentially causing a system crash or instability. The issue is fixed by initializing orig_he...
