| Subject: CVE-2022-48659: mm/slub: fix to return errno if kmalloc() fails |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| mm/slub: fix to return errno if kmalloc() fails |
| |
| In create_unique_id(), kmalloc(, GFP_KERNEL) can fail due to |
| out-of-memory, if it fails, return errno correctly rather than |
| triggering panic via BUG_ON(); |
| |
| kernel BUG at mm/slub.c:5893! |
| Internal error: Oops - BUG: 0 [#1] PREEMPT SMP |

| 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: |
