CVE-2022-49084

CVE-2022-49084 is a medium-severity vulnerability in Linux Linux Kernel with a CVSS 3.x base score of 5.5. It is not currently listed as actively exploited by CISA, and its EPSS exploit-prediction score is low. The underlying weakness is classified as CWE-476.

Key facts

Description

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().
