Summary
Ivan D Barrera, Christopher Bednarz, Mustafa Ismail, and Shiraz Saleem
discovered that the InfiniBand RDMA driver in the Linux kernel did not
properly check for zero-length STAG or MR registration. A remote attacker
could possibly use this to execute arbitrary code. (CVE-2023-25775)
Yu Hao discovered that the UBI driver in the Linux kernel did not properly
check for MTD with zero erasesize during device attachment. A local
privileged attacker could use this to cause a denial of service (system
crash). (CVE-2023-31085)
Manfred Rudigier discovered that the Intel(R) PCI-Express Gigabit (igb)
Ethernet driver in the Linux kernel did not properly validate received
frames that are larger than the set MTU size, leading to a buffer overflow
vulnerability. An attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2023-45871)
