In the Linux kernel, the following vulnerability has been resolved: riscv/ptrace: Use USER_REGSET_NOTE_TYPE for REGSET_CFI Fixes a warning while… (CVE-2026-53351)
A vulnerability in the Linux kernel related to the riscv/ptrace subsystem has been resolved. The issue involved improper use of USER_REGSET_NOTE_TYPE for REGSET_CFI, which caused a warning during core dump generation. The vulnerability does not impact confidentiality or integrity but affects availability by causing a warning that may lead to process aborts. No known exploits are reported in the wild. The severity is assessed as medium based on the impact to availability without compromise of data or privilege escalation.
AI Analysis
Technical Summary
The Linux kernel vulnerability CVE-2026-53351 concerns the riscv/ptrace component where USER_REGSET_NOTE_TYPE was not properly used for REGSET_CFI. This caused warnings during core dump operations, specifically aborts triggered by the elf_core_dump function. The issue affects availability by potentially aborting processes during core dumps but does not affect confidentiality or integrity. The vulnerability has been resolved in the Linux kernel. No exploits are known in the wild.
Potential Impact
The vulnerability impacts system availability by causing warnings and aborts during core dump generation on affected riscv systems. There is no impact on confidentiality or integrity. No known exploitation has been reported.
Mitigation Recommendations
A fix has been applied to the Linux kernel to resolve this issue. Users should update to the fixed kernel version once available. Patch status is not explicitly confirmed in the provided data; therefore, check the official Linux kernel advisories for the exact fixed versions and apply updates accordingly.
