Description

In the Linux kernel, the following vulnerability has been resolved: ipvs: fix reversed sequence option serialization hton_seq() expects the host-order source first and the unaligned network-order destination second. The version 1 sync sender passes these arguments in reverse for both sequence blocks. This leaves 24 bytes of the kmalloc-backed message unwritten. It may disclose stale heap data and replace the live connection sequence state with values read from the buffer. Pass the connection sequence state as the source and the message payload as the destination for both blocks.

Affected configurations

• linux linux kernel (>= 2.6.39 < 6.12.111) • linux linux kernel (>= 6.13 < 6.18.53) • linux linux kernel (>= 6.19 < 7.2.7) • linux linux kernel 7.3
