Linux Kernel Vulnerability in txgbe Driver Affecting Property Entries

CVE-2026-43082

What is CVE-2026-43082?

An improper resource management vulnerability exists in the Linux kernel's txgbe driver, specifically related to the allocation of struct property_entry arrays. This issue arises from a failure to allocate space for null terminators, resulting in potential instability or unexpected behavior during runtime. The driver currently allocates memory matching the exact number of entries utilized, neglecting to reserve an additional space for an empty property, which is necessary for correct operation. Updating the struct definition to include this extra element is essential for maintaining the integrity and reliability of the driver.
