In the Linux kernel, the following vulnerability has been resolved: usb: dwc3: gadget: check that event count does not exceed event buffer length The event count is read from register DWC3_GEVNTCOUNT. There is a check for the count being zero, but not for exceeding the event buffer length. Check that event count does not exceed event buffer length, avoiding an out-of-bounds access when memcpy'ing the event. Crash log: Unable to handle kernel paging request at virtual address ffffffc0129be000 pc : __memcpy+0x114/0x180 lr : dwc3_check_event_buf+0xec/0x348 x3 : 0000000000000030 x2 : 000000000000dfc4 x1 : ffffffc0129be000 x0 : ffffff87aad60080 Call trace: __memcpy+0x114/0x180 dwc3_interrupt+0x24/0x34

Technical Summary
This Red Hat security advisory (RHSA-2025:16354) addresses two kernel vulnerabilities in Red Hat Enterprise Linux 10. CVE-2025-37810 is a buffer overflow-related issue (CWE-787) in the USB dwc3 gadget driver where the event count was not properly checked against the event buffer length. CVE-2025-38566 (CWE-754) fixes improper handling of server-side TLS alerts in the sunrpc subsystem. The advisory provides updated kernel packages that correct these issues. The update is rated as having a moderate security impact by Red Hat Product Security. Systems must be rebooted after applying the update for the fixes to take effect.
Potential Impact
The vulnerabilities could potentially allow improper processing of USB events or TLS alerts, which may lead to system instability or security issues related to kernel operations. Red Hat rates the overall impact as moderate. There are no known exploits in the wild at this time.
Mitigation Recommendations
Red Hat has released updated kernel packages that address these vulnerabilities. Users should apply the security update for Red Hat Enterprise Linux 10 as described in the advisory and reboot their systems to activate the fixes. For detailed update instructions, refer to https://access.redhat.com/articles/11258. No additional mitigation steps are specified by the vendor.
