[PATCH OLK-5.10 0/2] Fixed CVE-2021-47037
by Zheng Zengkai 07 Mar '24

07 Mar '24

Q6afe-clocks driver can get reprobed. For example if the APR services are restarted after the firmware crash. However currently Q6afe-clocks driver will oops because hw.init will get cleared during first _probe call. Rewrite the driver to fill the clock data at runtime rather than using big static array of clocks. This issue was identified as CVE-2021-47037. Backport patches from linux 5.13-rc1 to fix this CVE.

Inside enic_queue_wq_skb, if some error happens, the skb will be freed by dev_kfree_skb(skb). But the freed skb is still used in skb_tx_timestamp(skb). My patch makes enic_queue_wq_skb() return error and goto spin_unlock() incase of error. The solution is provided by Govind. See https://lkml.org/lkml/2021/4/30/961.

[PATCH openEuler-22.03-LTS-SP2] nilfs2: fix potential use after free in nilfs_gccache_submit_read_data()
by ZhaoLong Wang 07 Mar '24

From: Pan Bian <bianpan2016(a)163.com> stable inclusion from stable-v5.10.198 commit 7130a87ca32396eb9bf48b71a2d42259ae44c6c7 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I95AT5 CVE: CVE-2023-52566 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 7ee29facd8a9c5a26079148e36bcf07141b3a6bc upstream. In nilfs_gccache_submit_read_data(), brelse(bh) is called to drop the reference count of bh when the call to nilfs_dat_translate() fails. If the reference count hits 0 and its owner page gets unlocked, bh may be freed. However, bh->b_page is dereferenced to put the page after that, which may result in a use-after-free bug. This patch moves the release operation after unlocking and putting the page. NOTE: The function in question is only called in GC, and in combination with current userland tools, address translation using DAT does not occur in that function, so the code path that causes this issue will not be executed. However, it is possible to run that code path by intentionally modifying the userland GC library or by calling the GC ioctl directly.
