[SRU Bionic, Focal, Jammy, OEM-6.0, Lunar 0/1] CVE-2023-45871

[Cengiz Can]

[Impact]
An issue was discovered in drivers/net/ethernet/intel/igb/igb_main.c in the IGB
driver in the Linux kernel before 6.5.3. A buffer size may not be adequate for
frames larger than the MTU.

[Fix]
Cherry picked from upstream.

[Test case]
Compile and boot tested only. QEMU >= v8.0.0 supports creating an emulated Intel
82576 Gigabit Network Connection in guest machines however this turned out to be
problematic in itself, particularly host->guest direction. Thus it was not a
valid confirmation on this fix.

[Potential regression]
Users of the Intel Gigabit Ethernet Network Driver might be affected. However,
this change only affects receive frames larger than the set MTU size.
