Message-ID: <2025091641-CVE-2023-53307-129b@gregkh> Date: Tue, 16 Sep 2025 18:11:52 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-cve-announce@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...nel.org> Subject: CVE-2023-53307: rbd: avoid use-after-free in do_rbd_add() when rbd_dev_create() fails From: Greg Kroah-Hartman <gregkh@...nel.org> Description =========== In the Linux kernel, the following vulnerability has been resolved: rbd: avoid use-after-free in do_rbd_add() when rbd_dev_create() fails If getting an ID or setting up a work queue in rbd_dev_create() fails, use-after-free on rbd_dev->rbd_client, rbd_dev->spec and rbd_dev->opts is triggered in do_rbd_add(). The root cause is that the ownership of these structures is transfered to rbd_dev prematurely and they all end up getting freed when rbd_dev_create() calls rbd_dev_free() prior to returning to do_rbd_add(). Found by Linux Verification Center (linuxtesting.org) with SVACE, an incomplete patch submitted by Natalia Petrova <n.petrova@...tech.ru>. The Linux kernel CVE team has assigned CVE-2023-53307 to this issue. Affected and fixed versions =========================== Issue introduced in 4.9 with commit 1643dfa4c2c827d6e2aa419df8c17b0f24090278 and fixed in 4.14.308 with commit 71da2a151ed1adb0aea4252b16d81b53012e7afd Issue introduced in 4.9 with commit 1643dfa4c2c827d6e2aa419df8c17b0f24090278 and fixed in 4.19.276 with commit e3cbb4d60764295992c95344f2d779439e8b34ce Issue introduced in 4.9 with commit 1643dfa4c2c827d6e2aa419df8c17b0f24090278 and fixed in 5.4.235 with commit 9787b328c42c13c4f31e7d5042c4e877e9344068 Issue introduced in 4.9 with commit 1643dfa4c2c827d6e2aa419df8c17b0f24090278 and fixed in 5.10.173 with commit ae16346078b1189aee934afd872d9f3d0a682c33 Issue introduced in 4.9 with commit 1643dfa4c2c827d6e2aa419df8c17b0f24090278 and fixed in 5.15.99 with commit a73783e4e0c4d1507794da211eeca75498544dff Issue introduced in 4.9 with commit 1643dfa4c2c827d6e2aa419df8c17b0f24090278 and fixed in 6.1.16 with commit faa7b683e436664fff5648426950718277831348 Issue introduced in 4.9 with commit 1643dfa4c2c827d6e2aa419df8c17b0f24090278 and fixed in 6.2.3 with commit cc8c0dd2984503ed09efa37bcafcef3d3da104e8 Issue introduced in 4.9 with commit 1643dfa4c2c827d6e2aa419df8c17b0f24090278 and fixed in 6.3 with commit f7c4d9b133c7a04ca619355574e96b6abf209fba 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-2023-53307 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/block/rbd.c 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/71da2a151ed1adb0aea4252b16d81b53012e7afd https://git.kernel.org/stable/c/e3cbb4d60764295992c95344f2d779439e8b34ce https://git.kernel.org/stable/c/9787b328c42c13c4f31e7d5042c4e877e9344068 https://git.kernel.org/stable/c/ae16346078b1189aee934afd872d9f3d0a682c33 https://git.kernel.org/stable/c/a73783e4e0c4d1507794da211eeca75498544dff https://git.kernel.org/stable/c/faa7b683e436664fff5648426950718277831348 https://git.kernel.org/stable/c/cc8c0dd2984503ed09efa37bcafcef3d3da104e8 https://git.kernel.org/stable/c/f7c4d9b133c7a04ca619355574e96b6abf209fba
