Description

In the Linux kernel, the following vulnerability has been resolved: net/smc: check smcd_v2_ext_offset when receiving proposal msg When receiving proposal msg in server, the field smcd_v2_ext_offset in proposal msg is from the remote client and can not be fully trusted. Once the value of smcd_v2_ext_offset exceed the max value, there has the chance to access wrong address, and crash may happen. This patch checks the value of smcd_v2_ext_offset before using it.

Affected configurations

• linux linux kernel (>= 5.10 < 5.15.176) • linux linux kernel (>= 5.16 < 6.1.122) • linux linux kernel (>= 6.2 < 6.6.68) • linux linux kernel (>= 6.7 < 6.12.7) • linux linux kernel 6.13
