CVE-2026-68450

A flaw was found in the Linux kernel's btrfs filesystem. When the addrelocroot function attempts to insert a duplicate mapping node into the relocroottree, the newly allocated node is not properly freed. This oversight can lead to a memory leak, potentially causing resource exhaustion and a Denia...

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...
