FKIE_CVE-2025-40252
Vulnerability from fkie_nvd - Published: 2025-12-04 16:16 - Updated: 2026-07-30 06:24
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: qlogic/qede: fix potential out-of-bounds read in qede_tpa_cont() and qede_tpa_end()
The loops in 'qede_tpa_cont()' and 'qede_tpa_end()', iterate
over 'cqe->len_list[]' using only a zero-length terminator as
the stopping condition. If the terminator was missing or
malformed, the loop could run past the end of the fixed-size array.
Add an explicit bound check using ARRAY_SIZE() in both loops to prevent
a potential out-of-bounds access.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
