CVE-2024-35984: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.3% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: i2c: smbus: fix NULL function pointer dereference Baruch reported an OOPS when using the designware controller as target only. Target-only modes break the assumption of one transfer function always being available. Fix this by always checking the pointer in __i2c_transfer. [wsa: dropped the simplification in core-smbus to avoid theoretical regressions]
