Description OSIDB Bzimport 2026-01-14 16:04:29 UTC 
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 (rx_pending) is not
set below the permitted length. This avoids UBSAN
shift-out-of-bounds errors when users passes small or zero
ring sizes via ethtool -G.
