CVE-2026-43296

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> octeontx2-af: Workaround SQM/PSE stalls by disabling sticky<br /> <br /> NIX SQ manager sticky mode is known to cause stalls when multiple SQs<br /> share an SMQ and transmit concurrently. Additionally, PSE may deadlock<br /> on transitions between sticky and non-sticky transmissions. There is<br /> also a credit drop issue observed when certain condition clocks are<br /> gated.<br /> <br /> work around these hardware errata by:<br /> - Disabling SQM sticky operation:<br /> - Clear TM6 (bit 15)<br /> - Clear TM11 (bit 14)<br /> - Disabling sticky → non-sticky transition path that can deadlock PSE:<br /> - Clear TM5 (bit 23)<br /> - Preventing credit drops by keeping the control-flow clock enabled:<br /> - Set TM9 (bit 21)<br /> <br /> These changes are applied via NIX_AF_SQM_DBG_CTL_STATUS. With this<br /> configuration the SQM/PSE maintain forward progress under load without<br /> credit loss, at the cost of disabling sticky optimizations.
