[PATCH openEuler-22.03-LTS-SP1] ext4: fix infinite loop when replaying fast_commit
by Zhihao Cheng 20 Aug '24

20 Aug '24

From: "Luis Henriques (SUSE)" <luis.henriques(a)linux.dev> mainline inclusion from mainline-v6.11-rc1 commit 907c3fe532253a6ef4eb9c4d67efb71fab58c706 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAKQ7X CVE: CVE-2024-43828 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When doing fast_commit replay an infinite loop may occur due to an uninitialized extent_status struct. ext4_ext_determine_insert_hole() does not detect the replay and calls ext4_es_find_extent_range(), which will return immediately without initializing the 'es' variable. Because 'es' contains garbage, an integer overflow may happen causing an infinite loop in this function, easily reproducible using fstest generic/039. This commit fixes this issue by unconditionally initializing the structure in function ext4_es_find_extent_range(). Thanks to Zhang Yi, for figuring out the real problem!

[PATCH OLK-5.10] PCI: endpoint: pci-epf-test: Make use of cached 'epc_features' in pci_epf_test_core_init()
by liwei 20 Aug '24

20 Aug '24

From: Manivannan Sadhasivam <manivannan.sadhasivam(a)linaro.org> mainline inclusion from mainline-v6.11-rc1 commit 5a5095a8bd1bd349cce1c879e5e44407a34dda8a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAKQ5P CVE: CVE-2024-43824 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Instead of getting the epc_features from pci_epc_get_features() API, use the cached pci_epf_test::epc_features value to avoid the NULL check. Since the NULL check is already performed in pci_epf_test_bind(), having one more check in pci_epf_test_core_init() is redundant and it is not possible to hit the NULL pointer dereference. Also with commit a01e7214bef9 ("PCI: endpoint: Remove "core_init_notifier" flag"), 'epc_features' got dereferenced without the NULL check, leading to the following false positive Smatch warning: drivers/pci/endpoint/functions/pci-epf-test.c:784 pci_epf_test_core_init() error: we previously assumed 'epc_features' could be null (see line 747) Thus, remove the redundant NULL check and also use the epc_features:: {msix_capable/msi_capable} flags directly to avoid local variables.
