[PATCH OLK-5.10] fbdev: savage: Error out if pixclock equals zero

From: Fullway Wang <fullwaywang(a)outlook.com> stable inclusion from stable-v5.10.211 commit 512ee6d6041e007ef5bf200c6e388e172a2c5b24 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E2Y8 CVE: CVE-2024-26778 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 04e5eac8f3ab2ff52fa191c187a46d4fdbc1e288 ] The userspace program could pass any values to the driver through ioctl() interface. If the driver doesn't check the value of pixclock, it may cause divide-by-zero error. Although pixclock is checked in savagefb_decode_var(), but it is not checked properly in savagefb_probe(). Fix this by checking whether pixclock is zero in the function savagefb_check_var() before info->var.pixclock is used as the divisor. This is similar to CVE-2022-3061 in i740fb which was fixed by commit 15cf0b8.

[PATCH openEuler-1.0-LTS] btrfs: dev-replace: properly validate device names
by Long Li 10 Apr '24

From: David Sterba <dsterba(a)suse.com> stable inclusion from stable-v4.19.273 commit 11d7a2e429c02d51e2dc90713823ea8b8d3d3a84 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E469 CVE: CVE-2024-26791 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- commit 9845664b9ee47ce7ee7ea93caf47d39a9d4552c4 upstream. There's a syzbot report that device name buffers passed to device replace are not properly checked for string termination which could lead to a read out of bounds in getname_kernel(). Add a helper that validates both source and target device name buffers. For devid as the source initialize the buffer to empty string in case something tries to read it later. This was originally analyzed and fixed in a different way by Edward Adam Davis (see links).
