Message-ID: <2025123021-CVE-2022-50886-a081@gregkh> Date: Tue, 30 Dec 2025 13:34:21 +0100 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-cve-announce@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...nel.org> Subject: CVE-2022-50886: mmc: toshsd: fix return value check of mmc_add_host() From: Greg Kroah-Hartman <gregkh@...nel.org> Description =========== In the Linux kernel, the following vulnerability has been resolved: mmc: toshsd: fix return value check of mmc_add_host() mmc_add_host() may return error, if we ignore its return value, the memory that allocated in mmc_alloc_host() will be leaked and it will lead a kernel crash because of deleting not added device in the remove path. So fix this by checking the return value and goto error path which will call mmc_free_host(), besides, free_irq() also needs be called. The Linux kernel CVE team has assigned CVE-2022-50886 to this issue. Affected and fixed versions =========================== Issue introduced in 3.19 with commit a5eb8bbd66ccf9f169419f9652544aec771b7c57 and fixed in 4.9.337 with commit 34ae492f8d172f0bd193c24cad588b35419ea47a Issue introduced in 3.19 with commit a5eb8bbd66ccf9f169419f9652544aec771b7c57 and fixed in 4.14.303 with commit 3329e7b7132ca727263fb0ee214cf52cc6dcaaad Issue introduced in 3.19 with commit a5eb8bbd66ccf9f169419f9652544aec771b7c57 and fixed in 4.19.270 with commit 4f6cb1c685f9e20a4a9fa565e442f5af4dad70ff Issue introduced in 3.19 with commit a5eb8bbd66ccf9f169419f9652544aec771b7c57 and fixed in 5.4.229 with commit 3dbb69a0242c31ea4c9eee22b1c41b515fe509a0 Issue introduced in 3.19 with commit a5eb8bbd66ccf9f169419f9652544aec771b7c57 and fixed in 5.10.163 with commit aabbedcb6c9a72d12d35dc672e83f0c8064d8a61 Issue introduced in 3.19 with commit a5eb8bbd66ccf9f169419f9652544aec771b7c57 and fixed in 5.15.86 with commit 6444079767b68b1fbed0e7668081146e80dcb719 Issue introduced in 3.19 with commit a5eb8bbd66ccf9f169419f9652544aec771b7c57 and fixed in 6.0.16 with commit 647e370dd0ef7e212d8d014bda748e461eab2e8c Issue introduced in 3.19 with commit a5eb8bbd66ccf9f169419f9652544aec771b7c57 and fixed in 6.1.2 with commit bfd77b194c94aefbde4efc30ddf8607dd9244672 Issue introduced in 3.19 with commit a5eb8bbd66ccf9f169419f9652544aec771b7c57 and fixed in 6.2 with commit f670744a316ea983113a65313dcd387b5a992444 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-2022-50886 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/mmc/host/toshsd.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/34ae492f8d172f0bd193c24cad588b35419ea47a https://git.kernel.org/stable/c/3329e7b7132ca727263fb0ee214cf52cc6dcaaad https://git.kernel.org/stable/c/4f6cb1c685f9e20a4a9fa565e442f5af4dad70ff https://git.kernel.org/stable/c/3dbb69a0242c31ea4c9eee22b1c41b515fe509a0 https://git.kernel.org/stable/c/aabbedcb6c9a72d12d35dc672e83f0c8064d8a61 https://git.kernel.org/stable/c/6444079767b68b1fbed0e7668081146e80dcb719 https://git.kernel.org/stable/c/647e370dd0ef7e212d8d014bda748e461eab2e8c https://git.kernel.org/stable/c/bfd77b194c94aefbde4efc30ddf8607dd9244672 https://git.kernel.org/stable/c/f670744a316ea983113a65313dcd387b5a992444
