GHSA-M3HV-89F3-WRRC

Vulnerability from github – Published: 2024-09-11 18:31 – Updated: 2025-05-09 09:33

Details

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

usb: xhci: Check for xhci->interrupters being allocated in xhci_mem_clearup()

If xhci_mem_init() fails, it calls into xhci_mem_cleanup() to mop up the damage. If it fails early enough, before xhci->interrupters is allocated but after xhci->max_interrupters has been set, which happens in most (all?) cases, things get uglier, as xhci_mem_cleanup() unconditionally derefences xhci->interrupters. With prejudice.

Gate the interrupt freeing loop with a check on xhci->interrupters being non-NULL.

Found while debugging a DMA allocation issue that led the XHCI driver on this exact path.

Severity ?

5.5 (Medium)
