In the Linux kernel, the following vulnerabilities have been resolved: xtensa: Fixed the refcount leak issue in the time.c file. In calibrateccount, the offindcompatiblenode function will return a node pointer with the refcount incremented. We should use ofnodeput when this function is no longer...
Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15
In the Linux kernel, the following vulnerabilities have been resolved: xtensa: xtfpga: Fixed a refcount leak bug in setup. In machinesetup, offindcompatiblenode will return a node pointer with the refcount incremented. We should use ofnodeput when it is no longer needed...
CVE-2026-12235
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...

CVE-2026-10669
On Xtensa SoCs built with CONFIGXTENSAMPU and CONFIGUSERSPACE, archbuffervalidate in arch/xtensa/core/mpu.c — the architecture hook that verifies a user-mode-supplied buffer is accessible to the calling user thread with the requested permission — defaulted its return value to 0 access permitted a...
CVE-2026-10669
Summary (CVE-2026-10669) : On Xtensa SoCs with CONFIG_XTENSA_MPU and CONFIG_USERSPACE, arch_buffer_validate() erroneously permits access when the buffer size rounds to a wrap of the 32-bit address space, bypassing MPU checks. This can let an unprivileged user-thread validate or copy memory it sho...
