FKIE_CVE-2022-49084

Vulnerability from fkie_nvd - Published: 2025-02-26 07:00 - Updated: 2026-08-04 10:17
Severity
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: qede: confirm skb is allocated before using qede_build_skb() assumes build_skb() always works and goes straight to skb_reserve(). However, build_skb() can fail under memory pressure. This results in a kernel panic because the skb to reserve is NULL. Add a check in case build_skb() failed to allocate and return NULL. The NULL return is handled correctly in callers to qede_build_skb().
