Upgrade SLES:15.6 kernel-syms to version 6.4.0-150600.23.17.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-syms package and not the kernel-syms package as distributed by SLES.
See How to fix? for SLES:15.6 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
phonet: fix rtm_phonet_notify() skb allocation
fill_route() stores three components in the skb:
- struct rtmsg
- RTA_DST (u8)
- RTA_OIF (u32)
Therefore, rtm_phonet_notify() should use
NLMSG_ALIGN(sizeof(struct rtmsg)) + nla_total_size(1) + nla_total_size(4)
