In the Linux kernel, the following vulnerability has been resolved:

usb: renesas_usbhs: Fix synchronous external abort on unbind

A synchronous external abort occurs on the Renesas RZ/G3S SoC if unbind is executed after the configuration sequence described above:

modprobe usb_f_ecm modprobe libcomposite modprobe configfs cd /sys/kernel/config/usb_gadget mkdir -p g1 cd g1 echo "0x1d6b" > idVendor echo "0x0104" > idProduct mkdir -p strings/0x409 echo "0123456789" > strings/0x409/serialnumber echo "Renesas." > strings/0x409/manufacturer echo "Ethernet Gadget" > strings/0x409/product mkdir -p functions/ecm.usb0 mkdir -p configs/c.1 mkdir -p configs/c.1/strings/0x409 echo "ECM" > configs/c.1/strings/0x409/configuration

if [ ! -L configs/c.1/ecm.usb0 ]; then ln -s functions/ecm.usb0 configs/c.1 fi

echo 11e20000.usb > UDC echo 11e20000.usb > /sys/bus/platform/drivers/renesas_usbhs/unbind

The displayed trace is as follows:

The issue occurs because usbhs_sys_function_pullup(), which accesses the IP registers, is executed after the USBHS clocks have been disabled. The problem is reproducible on the Renesas RZ/G3S SoC starting with the addition of module stop in the clock enable/disable APIs. With module stop functionality enabled, a bus error is expected if a master accesses a module whose clock has been stopped and module stop activated.

Disable the IP clocks at the end of remove.

Where an input reads “CISA's BOD 26-04 default”, no one has published it for this CVE, and CISA's implementation guidance says: “If “Automatable” and “Technical Impact” information items about a CVE ID are not available and the CVE ID is not in the KEV Catalog, CISA will treat its values as “no” and “total,” respectively, until CISA or a third party provides metadata about the CVE ID. CISA will always provide the Vulnrichment data for a CVE ID listed in the KEV Catalog.” Whether your system is publicly exposed is yours to answer.

Data Freshness Timeline

(refreshed 8× in last 7d / 40× in last 30d)

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). Most recent first.

Showing the most recent 99 of 231 refreshes on record for this CVE.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. 1 repeat row among the latest 100 is merged into the row it repeats. The 132 oldest rows on record are not shown and were not checked, so the counts can still include repeats.
