CVE-2026-98057

A flaw was found in the Linux kernel's tracing ring buffer. The persistent ring buffer validation logic fails to verify that the recorded sub-buffer count matches the expected page count in the metadata. A local attacker capable of manipulating persistent memory metadata could exploit this issue ...

CVE-2026-98057

The Linux kernel contains a vulnerability in the ring-buffer component. The issue arises because the code utilized meta->nr_subbufs without verifying that it correctly matched nr_pages + 1, despite the system assuming these two values were identical. To resolve this, a check was added to the p...
