UBUNTU-CVE-2025-40149
In the Linux kernel, the following vulnerability has been resolved: tls: Use skdstget and dstdevrcu in getnetdevforsock. getnetdevforsock is called during setsockopt, so not under RCU. Using skdstgetsk-dev could trigger UAF. Let's use skdstget and dstdevrcu. Note that the only -ndoskgetlowerdev...
CVE-2025-40170
CVE-2025-40170 affects the Linux kernel net subsystem. The vulnerability arises from unsafe accesses to dst->dev in sk_setup_caps() and related paths, not guarded by RCU. The fix adds RCU protection via dst_dev_rcu() (and dst_dev_rcu()-protected paths) in sk_setup_caps(), sk_dst_gso_max_size()...
CVE-2025-40168
In the Linux kernel, the following vulnerability has been resolved: smc: Use skdstget and dstdevrcu in smcclcprfxmatch. smcclcprfxmatch is called from smclistenwork and not under RCU nor RTNL. Using skdstgetsk-dev could trigger UAF. Let's use skdstget and dstdevrcu. Note that the returned value o...
CVE-2025-40158

CVE-2025-40158
CVE-2025-40158 concerns the Linux kernel IPv6 stack. The issue arises from improper RCU usage in ip6_output(), which attempted to use dst_dev_rcu() and, per the advisory, allows a potential UAF if the RCU handling is not correct. The description specifies that the fix is to use RCU in ip6_output(...
