CVE-2026-12235 Out-of-bounds write in Xtensa llext PLT relocation from malformed ELF (CWE-787)

The Linkable Loadable Extensions llext subsystem mis-handles PLT/RELA relocation entries when linking a relocatable partially-linked ELF extension. In llextlinkplt subsys/llext/llextlink.c, the relocatable branch tgt != NULL, the path used for Xtensa relocatable objects computed the patch address...

CVE-2026-12235

The CVE describes an out-of-bounds write in the Xtensa llext PLT relocation path. Specifically, during relocation in llext_link_plt(), the patch address is computed using rela.r_offset without validating it, allowing a crafted RELA entry with a large r_offset to write outside the extension’s text...
