Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2025-992656)

high Nessus Plugin ID 280220

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-992656 advisory.

 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:
