[PATCH openEuler-1.0-LTS] netfilter: ipset: add missing range check in bitmap_ip_uadt
by Dong Chenchen 14 Dec '24

14 Dec '24

From: Jeongjun Park <aha310510(a)gmail.com> stable inclusion from stable-v4.19.325 commit 3c20b5948f119ae61ee35ad8584d666020c91581 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB9NOX CVE: CVE-2024-53141 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 35f56c554eb1b56b77b3cf197a6b00922d49033d upstream. When tb[IPSET_ATTR_IP_TO] is not present but tb[IPSET_ATTR_CIDR] exists, the values of ip and ip_to are slightly swapped. Therefore, the range check for ip should be done later, but this part is missing and it seems that the vulnerability occurs. So we should add missing range checks and remove unnecessary range checks.

[PATCH openEuler-1.0-LTS] net: Fix icmp host relookup triggering ip_rt_bug

For ICMP err triggered by locally generated packets, dst->dev of output route is loopback. Generally, xfrm relookup verification is not required on loopback interfaces (net.ipv4.conf.lo.disable_xfrm = 1). Skip icmp relookup for locally generated packets to fix it.
