Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: ipvs: fix uninit-value for saddr in
 do_output_route4 syzbot reports for uninit-value for the saddr argument [1]. commit 4754957f04f5 ("ipvs:
 do not use random local source address for tunnels") already implies that the input value of saddr should
 be ignored but the code is still reading it which can prevent to connect the route. Fix it by changing the
 argument to ret_saddr. [1] BUG: KMSAN: uninit-value in do_output_route4+0x42c/0x4d0
