Doc Text:	A flaw was found in the Linux kernel related to the Extensible Host Controller Interface (xHCI) subsystem, specifically how it handles certain events. The issue arises when the xHCI driver improperly handles isochronous (isoc) Babble and Buffer Overrun events. The vulnerability occurs because the xHCI driver incorrectly assumes that the xHC (host controller) has released its ownership of a multi-TRB (Transfer Request Block) TD (Transfer Descriptor) after reporting an error on an early TRB. This assumption leads to the premature release of the TD, allowing remaining TRBs to be freed or overwritten, which can cause system instability or crashes.	Story Points:	---

Comment 8 Alex 2024-06-09 16:29:30 UTC

The result of automatic check (that is developed by Alexander Larkin) for this CVE-2024-26659 is: CHECK	Maybe valid. Check manually. with impact LOW (that is an approximation based on flags WRITE USB DMAorINTERRUPT  ; these flags parsed automatically based on patch data). Such automatic check happens only for Low/Moderates (and only when not from reporter, but parsing already existing CVE). Highs always checked manually (I check it myself and then we check it again in Remediation team). In rare cases some of the Moderates could be increased to High later.
