| Subject: CVE-2024-57983: mailbox: th1520: Fix memory corruption due to incorrect array size |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| mailbox: th1520: Fix memory corruption due to incorrect array size |
| |
| The functions th1520_mbox_suspend_noirq and th1520_mbox_resume_noirq are |
| intended to save and restore the interrupt mask registers in the MBOX |
| ICU0. However, the array used to store these registers was incorrectly |
| sized, leading to memory corruption when accessing all four registers. |
| |
| This commit corrects the array size to accommodate all four interrupt |
| mask registers, preventing memory corruption during suspend and resume |
| operations. |
| |
| The Linux kernel CVE team has assigned CVE-2024-57983 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
| https://git.kernel.org/stable/c/2cd12c7fba59f30369e8647a2b726c7280903304 |
