Doc Text:	A flaw was found in the Linux kernel's vmxnet3 network driver. When processing incoming packets under eXpress Data Path (XDP), the driver incorrectly calculates packet buffer lengths, leading to missing reserved tailroom. An attacker could exploit this issue by transmitting network traffic through the affected interface, triggering driver errors and leading to a Denial of Service (DoS).	Story Points:	---

Comment 3 Alex 2024-06-09 16:39:13 UTC

The result of automatic check (that is developed by Alexander Larkin) for this CVE-2024-27026 is: CHECK	Maybe valid. Check manually. with impact LOW (that is an approximation based on flags INIT WARNONLY  ; 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.
