- Page: https://www.vulneraibility.com/cve/CVE-2026-97451
- CVSS: 8.4
- Known exploited: not in CISA KEV as of our last sync
- EPSS: 0.14% (percentile 3.5)

## Affected versions

- Linux: affected >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 and < d0d89f2e16a874e0f8fb17045da293e8bedf8b21; >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 and < b96401812cbfbb4803faabeefa1f20b8562268b3; >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 and < 0e2021f49e64b3c8a9aa880d0c62a218bfe147ce; < 6.12.111; < 6.18.53; fixed in >= 6.12.111 and <= 6.12.*, >= 6.18.53 and <= 6.18.*, >= 7.2 and <= *

A version outside these ranges is not a statement that it is unaffected.

## Impact

Integer overflow in acpi_ex_opcode_3A_1T_1R() can cause kernel memory corruption, enabling local privilege escalation or kernel crash (DoS).

## Action

Immediate action required

## Recommendation

Install kernel updates containing the ACPICA fix and reboot affected hosts immediately.
