[PATCH openEuler-1.0-LTS] udf: Do not bother merging very long extents
by Xinyu Zheng 17 Oct '25

17 Oct '25

From: Jan Kara <jack(a)suse.cz> stable inclusion from stable-v4.19.276 commit 5d029799d381a9ee06209a222cae75f04c5d5304 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ID0RFS CVE: CVE-2023-53506 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 53cafe1d6d8ef9f93318e5bfccc0d24f27d41ced upstream. When merging very long extents we try to push as much length as possible to the first extent. However this is unnecessarily complicated and not really worth the trouble. Furthermore there was a bug in the logic resulting in corrupting extents in the file as syzbot reproducer shows. So just don't bother with the merging of extents that are too long together.

[PATCH OLK-6.6] pcmcia: Add error handling for add_interval() in do_validate_mem()
by Xiaomeng Zhang 17 Oct '25

17 Oct '25

From: Wentao Liang <vulab(a)iscas.ac.cn> stable inclusion from stable-v6.6.105 commit 4a81f78caa53e0633cf311ca1526377d9bff7479 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ID0R49 CVE: CVE-2025-39920 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 4a81f78caa53e0633cf311ca1526377d9bff7479 ] In the do_validate_mem(), the call to add_interval() does not handle errors. If kmalloc() fails in add_interval(), it could result in a null pointer being inserted into the linked list, leading to illegal memory access when sub_interval() is called next. This patch adds an error handling for the add_interval(). If add_interval() returns an error, the function will return early with the error code.
