FKIE_CVE-2024-35984
Vulnerability from fkie_nvd - Published: 2024-05-20 10:15 - Updated: 2024-11-21 09:21
Severity ?
Summary
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]
