CVE-2026-43296

A flaw was found in the Linux kernel's octeontx2-af driver. This vulnerability arises from issues within the NIX SQ Send Queue manager's sticky mode and the PSE Packet Stream Engine, which can lead to system stalls, deadlocks, and credit drops. When multiple Send Queues share a Send Message Queue...

CVE-2026-43296

In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: Workaround SQM/PSE stalls by disabling sticky NIX SQ manager sticky mode is known to cause stalls when multiple SQs share an SMQ and transmit concurrently. Additionally, PSE may deadlock on transitions between stick...

CVE-2026-43157 octeontx2-af: CGX: fix bitmap leaks

In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: CGX: fix bitmap leaks The RX/TX flow-control bitmaps rxfcpfvfbmap and txfcpfvfbmap are allocated by cgxlmacinit but never freed in cgxlmacexit. Unbinding and rebinding the driver therefore triggers kmemleak:...

CVE-2026-43157

Summary: CVE-2026-43157 affects the Linux kernel octeontx2-af CGX driver. The RX/TX flow-control bitmaps (rx_fc_pfvf_bmap, tx_fc_pfvf_bmap) are allocated during cgx_lmac_init() but not freed during cgx_lmac_exit(), enabling a kernel memory leak (kmemleak) when the driver is unbound and rebound. I...

SUSE CVE-2025-71137

In the Linux kernel, the following vulnerability has been resolved: octeontx2-pf: fix "UBSAN: shift-out-of-bounds error" This patch ensures that the RX ring size rxpending is not set below the permitted length. This avoids UBSAN shift-out-of-bounds errors when users passes small or zero ring size...

CVE-2025-71137

CVE-2025-71137 relates to the Linux kernel, where the octeontx2-pf driver patch fixes a UBSAN shift-out-of-bounds error by ensuring the RX ring size (rx_pending) is not set below the permitted length. This prevents UBSAN faults when users pass small or zero ring sizes via ethtool -G. The fix is a...
