  "details": "In the Linux kernel, the following vulnerability has been resolved:  net: stmmac: dwmac1000: clear the RGMII status interrupt  Since commit 2e2c878a3141 (\"net: stmmac: remove SGMII/RGMII/SMII interrupt handling\") nothing on the RGMII path reads GMAC_RGSMIIIS, so RGSMIIIS stays pending behind GMAC_INT_MASK from the first link change on. stmmac_resume() resets the MAC in stmmac_hw_setup(); the reset sets GMAC_INT_MASK to 0 until dwmac1000_core_init() writes the mask again, and the pending status storms the line:    dwmac_dma_interrupt: unexpected status 04000000  A register dump at the first message on ODROID-HC4 showed it:    core int_status 00000001 int_mask 00000000 pmt 00000000 rgsmiiis 0000000d  When the resume thread runs on the CPU that takes the MAC interrupt, the storm starves it: a soft lockup, then a watchdog reset or a hang.  Read GMAC_RGSMIIIS in dwmac1000_irq_status() when the status is not masked, as the driver did before 2e2c878a3141; the read clears it.  Wake-on-LAN resume from s2idle with the resume thread and the MAC interrupt on one CPU: Helios64 (dwmac-rk), 7.3-rc6, soft-locked in 3 of 3 resumes without a fix and in 0 of 10 with this patch; it ran with an out-of-tree dwmac-rk change that keeps the GMAC powered across suspend. ODROID-HC4 (dwmac-meson8b): 0 of 10 with this patch, 2 of 2 without a fix on a 7.3-rc5 build. irq_rgmii_n went up by one per resume.",
