[PATCH openEuler-1.0-LTS 1/2] drm: Fix use-after-free read in drm_getunique()
by Yongqiang Liu 30 May '23

30 May '23

From: Desmond Cheong Zhi Xi <desmondcheongzx(a)gmail.com> stable inclusion from stable-v4.19.195 commit 7d233ba700ceb593905ea82b42dadb4ec8ef85e9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I52XND CVE: CVE-2022-1280 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit b436acd1cf7fac0ba987abd22955d98025c80c2b upstream. There is a time-of-check-to-time-of-use error in drm_getunique() due to retrieving file_priv->master prior to locking the device's master mutex. An example can be seen in the crash report of the use-after-free error found by Syzbot: https://syzkaller.appspot.com/bug?id=148d2f1dfac64af52ffd27b661981a540724f8… In the report, the master pointer was used after being freed. This is because another process had acquired the device's master mutex in drm_setmaster_ioctl(), then overwrote fpriv->master in drm_new_set_master(). The old value of fpriv->master was subsequently freed before the mutex was unlocked. To fix this, we lock the device's master mutex before retrieving the pointer from from fpriv->master. This patch passes the Syzbot reproducer test.

[PATCH] perf/smmuv3: Enable HiSilicon Erratum quirk

From: Yicong Yang <yangyicong(a)hisilicon.com> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I798Y2 CVE: NA ---------------------------------------------------------------------- Some HiSilicon SMMU PMCG suffers the erratum that the global PMU disable control sometimes fail to disable each used the counters. This will lead to error or inaccurate data since before we enable the counters the counter's still counting for the event used in last perf session. This patch tries to fix this by hardening the global disable process. Before disable the PMU, writing an invalid event type (0xff) to focibly stop the counters.

It also avoids the potential KASAN / syzkaller failure, as a bonus.
