CVE-2026-97617

A flaw was found in the Linux kernel's ring buffer subsystem. A race condition occurs when updating the buffer configuration concurrently with memory mapping operations. Because the kernel applies the new buffer order before verifying that resizing is permitted across all processors, the system c...

CVE-2026-97573

A flaw was found in the Linux kernel's Broadcom NetXtreme-E bnxten network driver. The driver fails to verify memory allocation success during receive ring buffer resets, ignoring failure responses when memory is low. A local user or network event that triggers a reset under memory exhaustion can...

CVE-2026-97572

A flaw was found in the Linux kernel's Broadcom NetXtreme bnxten network driver. This flaw can result in a Denial of Service DoS or memory corruption when the device is initialized or reset under low-memory conditions. The driver ignores memory allocation errors during receive ring buffer setup a...

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...

CVE-2026-97617

A vulnerability exists in the Linux kernel 's ring-buffer mechanism. The ring_buffer_subbuf_order_set() function incorrectly stores a new order before checking if any CPUs have resizing disabled. Because __rb_map_vma() reads buffer->subbuf_order without holding the buffer->mutex, a race con...
