kernel: liquidio: Adjust a NULL pointer handling path in lio_vf_rep_copy_packet

A vulnerability was found in the Linux kernel's LiquidIO driver within the liovfrepcopypacket function, where the issue arises from a NULL pointer check on pginfo-page that is not appropriately handled before it is passed to skbaddrxfrag, potentially leading to a NULL pointer dereference...

UBUNTU-CVE-2024-45030

In the Linux kernel, the following vulnerability has been resolved: igb: cope with large MAXSKBFRAGS Sabrina reports that the igb driver does not cope well with large MAXSKBFRAG values: setting MAXSKBFRAG to 45 causes payload corruption on TX. An easy reproducer is to run ssh to connect to the...

In the Linux kernel, the following vulnerability has been resolved: IB/mlx5: Fix initializing CQ fragments buffer The function initcqfragbuf can be called to initialize the current CQ fragments buffer cq-buf, or the temporary cq-resizebuf that is filled during CQ resize operation. However, the...

The vulnerability of the can_map_frag() function in the net/ipv4/tcp.c module of the Linux operating system’s IPv4 protocol implementation allows a attacker to cause a service failure.

The vulnerability of the canmapfrag function in the net/ipv4/tcp.c module of the Linux operating system’s IPv4 protocol implementation is related to the lack of necessary data validation checks. Exploiting this vulnerability could allow a remote attacker to cause service interruptions...
