PT-2024-34090

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 6.6.61 Description: A crash can occur in the Linux kernel when a small gso max size or gso ipv4 max size is configured, leading to an underflow in sk dst gso max size. This underflow may trigger a BUG ON crash...

DEBIAN-CVE-2022-49026

In the Linux kernel, the following vulnerability has been resolved: e100: Fix possible use after free in e100xmitprepare In e100xmitprepare, if we can't map the skb, then return -ENOMEM, so e100xmitframe will return NETDEVTXBUSY and the upper layer will resend the skb. But the skb is already free...

kernel: net: bridge: xmit: make sure we have at least eth header len bytes

A vulnerability was found in the Linux kernel in the net: bridge component, where the xmit function in the bridge device could trigger an uninitialized value error if a short skb less than the required ETHHLEN bytes is sent. This condition could cause unexpected behavior due to insufficient check...
