CVE-2026-89555 mpls: reload header after pskb_may_pull()

In the Linux kernel, the following vulnerability has been resolved: mpls: reload header after pskbmaypull mplsselectmultipath calls mplsmultipathhash to choose a nexthop when an MPLS route has multiple nexthops. While walking the MPLS label stack, the hash routine caches hdr for the current label...

CVE-2026-89555

CVE-2026-89555 is a use-after-free in the Linux kernel's MPLS subsystem. In mpls_select_multipath(), a cached header pointer (hdr) is not reloaded after pskb_may_pull() reallocates the skb head via pskb_expand_head(), leaving hdr pointing to freed memory. A remote attacker can trigger the bug by ...

CVE-2026-89552

This Linux kernel vulnerability affects param_set_charp() in the kernel's params subsystem. The root cause is that the previous parameter value is freed before the replacement allocation succeeds; if kmalloc_parameter() fails, the parameter is left as NULL , leading to a kernel NULL pointer deref...
