CVE-2026-23353

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.19.0-0.rc7.260128g1f97d9dcf5364.49.eln154.x86 64

Description The Linux kernel contains a flaw within the ice network driver related to the ethtool offline loopback test. Following the conversion to page pool allocation, the test causes a kernel NULL pointer dereference, leading to a system crash. The issue arises because the receive ring for ICE Virtual Switch Interface (VSI) loopback tests was not properly initialized for libeth, resulting in an attempt to access an uninitialized memory location.

Recommendations Update the Linux kernel to version 6.19.0-0.rc7.260128g1f97d9dcf5364.49.eln154.x86 64 or a later version that includes the fix.
