Date: Wed, 1 May 2024 15:00:32 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-cve-announce@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Subject: CVE-2024-27059: USB: usb-storage: Prevent divide-by-0 error in isd200_ata_command Description =========== In the Linux kernel, the following vulnerability has been resolved: USB: usb-storage: Prevent divide-by-0 error in isd200_ata_command The isd200 sub-driver in usb-storage uses the HEADS and SECTORS values in the ATA ID information to calculate cylinder and head values when creating a CDB for READ or WRITE commands. The calculation involves division and modulus operations, which will cause a crash if either of these values is 0. While this never happens with a genuine device, it could happen with a flawed or subversive emulation, as reported by the syzbot fuzzer. Protect against this possibility by refusing to bind to the device if either the ATA_ID_HEADS or ATA_ID_SECTORS value in the device's ID information is 0. This requires isd200_Initialization() to return a negative error code when initialization fails; currently it always returns 0 (even when there is an error). The Linux kernel CVE team has assigned CVE-2024-27059 to this issue. Affected and fixed versions =========================== Issue introduced in 2.6.12 with commit 1da177e4c3f4 and fixed in 4.19.312 with commit 9968c701cba7 Issue introduced in 2.6.12 with commit 1da177e4c3f4 and fixed in 5.4.274 with commit eb7b01ca7781 Issue introduced in 2.6.12 with commit 1da177e4c3f4 and fixed in 5.10.215 with commit 284fb1003d5d Issue introduced in 2.6.12 with commit 1da177e4c3f4 and fixed in 5.15.154 with commit 6c1f36d92c0a Issue introduced in 2.6.12 with commit 1da177e4c3f4 and fixed in 6.1.84 with commit f42ba916689f Issue introduced in 2.6.12 with commit 1da177e4c3f4 and fixed in 6.6.24 with commit 871fd7b10b56 Issue introduced in 2.6.12 with commit 1da177e4c3f4 and fixed in 6.7.12 with commit 3a67d4ab9e73 Issue introduced in 2.6.12 with commit 1da177e4c3f4 and fixed in 6.8 with commit 014bcf41d946 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-2024-27059 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/usb/storage/isd200.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/9968c701cba7eda42e5f0052b040349d6222ae34 https://git.kernel.org/stable/c/eb7b01ca778170654e1c76950024270ba74b121f https://git.kernel.org/stable/c/284fb1003d5da111019b9e0bf99b084fd71ac133 https://git.kernel.org/stable/c/6c1f36d92c0a8799569055012665d2bb066fb964 https://git.kernel.org/stable/c/f42ba916689f5c7b1642092266d2f53cf527aaaa https://git.kernel.org/stable/c/871fd7b10b56d280990b7e754f43d888382ca325 https://git.kernel.org/stable/c/3a67d4ab9e730361d183086dfb0ddd8c61f01636 https://git.kernel.org/stable/c/014bcf41d946b36a8f0b8e9b5d9529efbb822f49
