| Subject: CVE-2024-50211: udf: refactor inode_bmap() to handle error |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| udf: refactor inode_bmap() to handle error |
| |
| Refactor inode_bmap() to handle error since udf_next_aext() can return |
| error now. On situations like ftruncate, udf_extend_file() can now |
| detect errors and bail out early without resorting to checking for |
| particular offsets and assuming internal behavior of these functions. |
| |
| The Linux kernel CVE team has assigned CVE-2024-50211 to this issue. |
| |
| |
| Affected and fixed versions |
| =========================== |
| |
| Fixed in 6.6.59 with commit 493447dd8336607fce426f7879e581095f6c606e |
| Fixed in 6.11.6 with commit b22d9a5698abf04341f8fbc30141e0673863c3a6 |
| Fixed in 6.12 with commit c226964ec786f3797ed389a16392ce4357697d24 |

| Please see https://www.kernel.org for a full list of currently supported |
| kernel versions by the kernel community. |
| |
| Unaffected versions might change over time as fixes are backported to |
| older supported kernel versions. The official CVE entry at |
| https://cve.org/CVERecord/?id=CVE-2024-50211 |
| will be updated if fixes are backported, please check that for the most |
| up to date information about 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/493447dd8336607fce426f7879e581095f6c606e |
