Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a flaw related to packet handling in the bcmgenet network driver. Occasionally, oversized packets from the hardware may exceed the allocated buffer size, potentially triggering a panic. A check has been added to drop these oversized packets, preventing the invocation of skb over panic() and allowing processing to continue.
