[PATCH OLK-6.6] exfat: fix the infinite loop in exfat_readdir()
by Cai Xinchen 23 Jan '25

23 Jan '25

From: Yuezhang Mo <Yuezhang.Mo(a)sony.com> stable inclusion from stable-v6.6.72 commit dc1d7afceb982e8f666e70a582e6b5aa806de063 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBJ6S6 CVE: CVE-2024-57940 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit fee873761bd978d077d8c55334b4966ac4cb7b59 ] If the file system is corrupted so that a cluster is linked to itself in the cluster chain, and there is an unused directory entry in the cluster, 'dentry' will not be incremented, causing condition 'dentry < max_dentries' unable to prevent an infinite loop. This infinite loop causes s_lock not to be released, and other tasks will hang, such as exfat_sync_fs(). This commit stops traversing the cluster chain when there is unused directory entry in the cluster to avoid this infinite loop.

[PATCH OLK-6.6] fs/proc/kcore.c: Clear ret value in read_kcore_iter after successful iov_iter_zero
by Li Huafei 23 Jan '25

23 Jan '25

From: Jiri Olsa <jolsa(a)kernel.org> stable inclusion from stable-v6.6.64 commit 6868deee4a6bb8d324e883e2f540aaa33499a0f9 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBJCJ6 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 088f294609d8f8816dc316681aef2eb61982e0da upstream. If iov_iter_zero succeeds after failed copy_from_kernel_nofault, we need to reset the ret value to zero otherwise it will be returned as final return value of read_kcore_iter. This fixes objdump -d dump over /proc/kcore for me.
