[PATCH openEuler-22.03-LTS-SP1] locking/ww_mutex/test: Fix potential workqueue corruption
by Xie XiuQi 31 May '24

31 May '24

From: John Stultz <jstultz(a)google.com> stable inclusion from stable-v5.10.202 commit 9ed2d68b3925145f5f51c46559484881d6082f75 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9RFIG CVE: CVE-2023-52836 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit bccdd808902f8c677317cec47c306e42b93b849e ] In some cases running with the test-ww_mutex code, I was seeing odd behavior where sometimes it seemed flush_workqueue was returning before all the work threads were finished. Often this would cause strange crashes as the mutexes would be freed while they were being used. Looking at the code, there is a lifetime problem as the controlling thread that spawns the work allocates the "struct stress" structures that are passed to the workqueue threads. Then when the workqueue threads are finished, they free the stress struct that was passed to them. Unfortunately the workqueue work_struct node is in the stress struct. Which means the work_struct is freed before the work thread returns and while flush_workqueue is waiting. It seems like a better idea to have the controlling thread both allocate and free the stress structures, so that we can be sure we don't corrupt the workqueue by freeing the structure prematurely. So this patch reworks the test to do so, and with this change I no longer see the early flush_workqueue returns.

[PATCH openEuler-1.0-LTS] net/mlx4_en: Fix an use-after-free bug in mlx4_en_try_alloc_resources()

From: Zhou Qingyang <zhou1615(a)umn.edu> stable inclusion from stable-v4.19.220 commit 676dc7d9b15bf8733233a2db1ec3f9091ab34275 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9S1ZN CVE: CVE-2021-47541 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit addad7643142f500080417dd7272f49b7a185570 upstream. In mlx4_en_try_alloc_resources(), mlx4_en_copy_priv() is called and tmp->tx_cq will be freed on the error path of mlx4_en_copy_priv(). After that mlx4_en_alloc_resources() is called and there is a dereference of &tmp->tx_cq[t][i] in mlx4_en_alloc_resources(), which could lead to a use after free problem on failure of mlx4_en_copy_priv(). Fix this bug by adding a check of mlx4_en_copy_priv() This bug was found by a static analyzer. The analysis employs differential checking to identify inconsistent security operations (e.g., checks or kfrees) between two code paths and confirms that the inconsistent operations are not recovered in the current function or the callers, so they constitute bugs. Note that, as a bug found by static analysis, it can be a false positive or hard to trigger. Multiple researchers have cross-reviewed the bug. Builds with CONFIG_MLX4_EN=m show no new warnings, and our static analyzer no longer warns about this code.

by Luo Gengkun 31 May '24

From: Junhao He <hejunhao3(a)huawei.com> mainline inclusion from mainline-v6.7-rc1 commit b805cafc604bfdb671fae7347a57f51154afa735 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RKWV CVE: CVE-2023-52859 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When we fail to register the uncore pmu, the pmu context may not been allocated. The error handing will call cpuhp_state_remove_instance() to call uncore pmu offline callback, which migrate the pmu context. Since that's liable to lead to some kind of use-after-free. Use cpuhp_state_remove_instance_nocalls() instead of cpuhp_state_remove_instance() so that the notifiers don't execute after the PMU device has been failed to register.
