| Subject: CVE-2024-27413: efi/capsule-loader: fix incorrect allocation size |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| efi/capsule-loader: fix incorrect allocation size |
| |
| gcc-14 notices that the allocation with sizeof(void) on 32-bit architectures |
| is not enough for a 64-bit phys_addr_t: |
| |
| drivers/firmware/efi/capsule-loader.c: In function 'efi_capsule_open': |
| drivers/firmware/efi/capsule-loader.c:295:24: error: allocation of insufficient size '4' for type 'phys_addr_t' {aka 'long long unsigned int'} with size '8' [-Werror=alloc-size] |
| 295 | cap_info->phys = kzalloc(sizeof(void *), GFP_KERNEL); |
| | ^ |
| |
| Use the correct type instead here. |
| |
| The Linux kernel CVE team has assigned CVE-2024-27413 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: |
