[openEuler-1.0-LTS] KVM: Stop looking for coalesced MMIO zones if the bus is destroyed
by Zheng Yejian 02 Mar '24

02 Mar '24

From: Sean Christopherson <seanjc(a)google.com> mainline inclusion from mainline-v5.13-rc1 commit 5d3c4c79384af06e3c8e25b7770b6247496b4417 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I94VOT CVE: CVE-2021-47060 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… --------------------------- Abort the walk of coalesced MMIO zones if kvm_io_bus_unregister_dev() fails to allocate memory for the new instance of the bus. If it can't instantiate a new bus, unregister_dev() destroys all devices _except_ the target device. But, it doesn't tell the caller that it obliterated the bus and invoked the destructor for all devices that were on the bus. In the coalesced MMIO case, this can result in a deleted list entry dereference due to attempting to continue iterating on coalesced_zones after future entries (in the walk) have been deleted. Opportunistically add curly braces to the for-loop, which encompasses many lines but sneaks by without braces due to the guts being a single if statement.

[PATCH openEuler-1.0-LTS v2] net: openvswitch: limit the number of recursions from action sets
by Dong Chenchen 02 Mar '24

02 Mar '24

From: Aaron Conole <aconole(a)redhat.com> mainline inclusion from mainline-v6.8-rc3 commit 6e2f90d31fe09f2b852de25125ca875aabd81367 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I91L17 CVE: CVE-2024-1151 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The ovs module allows for some actions to recursively contain an action list for complex scenarios, such as sampling, checking lengths, etc. When these actions are copied into the internal flow table, they are evaluated to validate that such actions make sense, and these calls happen recursively. The ovs-vswitchd userspace won't emit more than 16 recursion levels deep. However, the module has no such limit and will happily accept limits larger than 16 levels nested. Prevent this by tracking the number of recursions happening and manually limiting it to 16 levels nested. The initial implementation of the sample action would track this depth and prevent more than 3 levels of recursion, but this was removed to support the clone use case, rather than limited at the current userspace limit.

From: Aaron Conole <aconole(a)redhat.com> mainline inclusion from mainline-v6.8-rc3 commit 6e2f90d31fe09f2b852de25125ca875aabd81367 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I91L17 CVE: CVE-2024-1151 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The ovs module allows for some actions to recursively contain an action list for complex scenarios, such as sampling, checking lengths, etc. When these actions are copied into the internal flow table, they are evaluated to validate that such actions make sense, and these calls happen recursively. The ovs-vswitchd userspace won't emit more than 16 recursion levels deep. However, the module has no such limit and will happily accept limits larger than 16 levels nested. Prevent this by tracking the number of recursions happening and manually limiting it to 16 levels nested. The initial implementation of the sample action would track this depth and prevent more than 3 levels of recursion, but this was removed to support the clone use case, rather than limited at the current userspace limit.

[PATCH openEuler-1.0-LTS] Revert "blk-mq: Fix memory leak in blk_mq_init_allocated_queue error handling"
by Li Lingfeng 02 Mar '24

02 Mar '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I959FN CVE: NA -------------------------------- This reverts commit 961e2d0bd3b537aa39b58b074aec4a6c6a9fea47. When blk_mq_init_allocated_queue() fail, blk_mq_init_queue() will catch the error code and call blk_cleanup_queue() to release resource. So it's not necessary to call blk_mq_del_queue_tag_set() in blk_mq_init_allocated_queue(). What's more, hctx can't be released since commit 73d9c8d4c001 ("blk-mq: Fix memory leak in blk_mq_init_allocated_queue error handling") set q->nr_hw_queues as zero.
