Ubuntu: (Multiple Advisories) (CVE-2024-35980): Linux kernel vulnerabilities Severity 5 CVSS (AV:L/AC:L/Au:S/C:N/I:N/A:C) Published 05/20/2024 Created 07/12/2024 Added 07/12/2024 Modified 01/30/2025 Description In the Linux kernel, the following vulnerability has been resolved: arm64: tlb: Fix TLBI RANGE operand KVM/arm64 relies on TLBI RANGE feature to flush TLBs when the dirty pages are collected by VMM and the page table entries become write protected during live migration. Unfortunately, the operand passed to the TLBI RANGE instruction isn't correctly sorted out due to the commit 117940aa6e5f ("KVM: arm64: Define kvm_tlb_flush_vmid_range()"). It leads to crash on the destination VM after live migration because TLBs aren't flushed completely and some of the dirty pages are missed. For example, I have a VM where 8GB memory is assigned, starting from 0x40000000 (1GB). Note that the host has 4KB as the base page size. In the middile of migration, kvm_tlb_flush_vmid_range() is executed to flush TLBs. It passes MAX_TLBI_RANGE_PAGES as the argument to __kvm_tlb_flush_vmid_range() and __flush_s2_tlb_range_op(). SCALE#3 and NUM#31, corresponding to MAX_TLBI_RANGE_PAGES, isn't supported by __TLBI_RANGE_NUM(). In this specific case, -1 has been returned from __TLBI_RANGE_NUM() for SCALE#3/2/1/0 and rejected by the loop in the __flush_tlb_range_op() until the variable @scale underflows and becomes -9, 0xffff708000040000 is set as the operand. The operand is wrong since it's sorted out by __TLBI_VADDR_RANGE() according to invalid @scale and @num. Fix it by extending __TLBI_RANGE_NUM() to support the combination of SCALE#3 and NUM#31. With the changes, [-1 31] instead of [-1 30] can be returned from the macro, meaning the TLBs for 0x200000 pages in the above example can be flushed in one shoot with SCALE#3 and NUM#31. The macro TLBI_RANGE_MASK is dropped since no one uses it any more. The comments are also adjusted accordingly.

Ubuntu: (Multiple Advisories) (CVE-2024-35971): Linux kernel vulnerabilities Severity 4 CVSS (AV:L/AC:M/Au:N/C:P/I:P/A:P) Published 05/20/2024 Created 07/12/2024 Added 07/12/2024 Modified 07/29/2024 Description In the Linux kernel, the following vulnerability has been resolved: net: ks8851: Handle softirqs at the end of IRQ thread to fix hang The ks8851_irq() thread may call ks8851_rx_pkts() in case there are any packets in the MAC FIFO, which calls netif_rx(). This netif_rx() implementation is guarded by local_bh_disable() and local_bh_enable(). The local_bh_enable() may call do_softirq() to run softirqs in case any are pending. One of the softirqs is net_rx_action, which ultimately reaches the driver .start_xmit callback. If that happens, the system hangs. The entire call chain is below: ks8851_start_xmit_par from netdev_start_xmit netdev_start_xmit from dev_hard_start_xmit dev_hard_start_xmit from sch_direct_xmit sch_direct_xmit from __dev_queue_xmit __dev_queue_xmit from __neigh_update __neigh_update from neigh_update neigh_update from arp_process.constprop.0 arp_process.constprop.0 from __netif_receive_skb_one_core __netif_receive_skb_one_core from process_backlog process_backlog from __napi_poll.constprop.0 __napi_poll.constprop.0 from net_rx_action net_rx_action from __do_softirq __do_softirq from call_with_stack call_with_stack from do_softirq do_softirq from __local_bh_enable_ip __local_bh_enable_ip from netif_rx netif_rx from ks8851_irq ks8851_irq from irq_thread_fn irq_thread_fn from irq_thread irq_thread from kthread kthread from ret_from_fork The hang happens because ks8851_irq() first locks a spinlock in ks8851_par.c ks8851_lock_par() spin_lock_irqsave(&ksp->lock, ...) and with that spinlock locked, calls netif_rx(). Once the execution reaches ks8851_start_xmit_par(), it calls ks8851_lock_par() again which attempts to claim the already locked spinlock again, and the hang happens. Move the do_softirq() call outside of the spinlock protected section of ks8851_irq() by disabling BHs around the entire spinlock protected section of ks8851_irq() handler. Place local_bh_enable() outside of the spinlock protected section, so that it can trigger do_softirq() without the ks8851_par.c ks8851_lock_par() spinlock being held, and safely call ks8851_start_xmit_par() without attempting to lock the already locked spinlock. Since ks8851_irq() is protected by local_bh_disable()/local_bh_enable() now, replace netif_rx() with __netif_rx() which is not duplicating the local_bh_disable()/local_bh_enable() calls.

Ubuntu: (Multiple Advisories) (CVE-2024-35958): Linux kernel vulnerabilities Severity 4 CVSS (AV:L/AC:M/Au:N/C:P/I:P/A:P) Published 05/20/2024 Created 07/12/2024 Added 07/12/2024 Modified 09/20/2024 Description In the Linux kernel, the following vulnerability has been resolved: net: ena: Fix incorrect descriptor free behavior ENA has two types of TX queues: - queues which only process TX packets arriving from the network stack - queues which only process TX packets forwarded to it by XDP_REDIRECT or XDP_TX instructions The ena_free_tx_bufs() cycles through all descriptors in a TX queue and unmaps + frees every descriptor that hasn't been acknowledged yet by the device (uncompleted TX transactions). The function assumes that the processed TX queue is necessarily from the first category listed above and ends up using napi_consume_skb() for descriptors belonging to an XDP specific queue. This patch solves a bug in which, in case of a VF reset, the descriptors aren't freed correctly, leading to crashes.

Ubuntu: (Multiple Advisories) (CVE-2024-35955): Linux kernel vulnerabilities Severity 4 CVSS (AV:L/AC:M/Au:N/C:P/I:P/A:P) Published 05/20/2024 Created 07/12/2024 Added 07/12/2024 Modified 09/20/2024 Description In the Linux kernel, the following vulnerability has been resolved: kprobes: Fix possible use-after-free issue on kprobe registration When unloading a module, its state is changing MODULE_STATE_LIVE -> MODULE_STATE_GOING -> MODULE_STATE_UNFORMED. Each change will take a time. `is_module_text_address()` and `__module_text_address()` works with MODULE_STATE_LIVE and MODULE_STATE_GOING. If we use `is_module_text_address()` and `__module_text_address()` separately, there is a chance that the first one is succeeded but the next one is failed because module->state becomes MODULE_STATE_UNFORMED between those operations. In `check_kprobe_address_safe()`, if the second `__module_text_address()` is failed, that is ignored because it expected a kernel_text address. But it may have failed simply because module->state has been changed to MODULE_STATE_UNFORMED. In this case, arm_kprobe() will try to modify non-exist module text address (use-after-free). To fix this problem, we should not use separated `is_module_text_address()` and `__module_text_address()`, but use only `__module_text_address()` once and do `try_module_get(module)` which is only available with MODULE_STATE_LIVE.

VMware Photon OS: CVE-2024-35960 Severity 9 CVSS (AV:N/AC:L/Au:N/C:N/I:C/A:C) Published 05/20/2024 Created 01/21/2025 Added 01/20/2025 Modified 02/04/2025 Description In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Properly link new fs rules into the tree Previously, add_rule_fg would only add newly created rules from the handle into the tree when they had a refcount of 1. On the other hand, create_flow_handle tries hard to find and reference already existing identical rules instead of creating new ones. These two behaviors can result in a situation where create_flow_handle 1) creates a new rule and references it, then 2) in a subsequent step during the same handle creation references it again, resulting in a rule with a refcount of 2 that is not linked into the tree, will have a NULL parent and root and will result in a crash when the flow group is deleted because del_sw_hw_rule, invoked on rule deletion, assumes node->parent is != NULL. This happened in the wild, due to another bug related to incorrect handling of duplicate pkt_reformat ids, which lead to the code in create_flow_handle incorrectly referencing a just-added rule in the same flow handle, resulting in the problem described above. Full details are at [1]. This patch changes add_rule_fg to add new rules without parents into the tree, properly initializing them and avoiding the crash. This makes it more consistent with how rules are added to an FTE in create_flow_handle.

Oracle Linux: CVE-2024-35195: ELSA-2025-0012:python-requests security update (MODERATE) (Multiple Advisories) Severity 5 CVSS (AV:L/AC:H/Au:M/C:C/I:C/A:N) Published 05/20/2024 Created 01/07/2025 Added 01/03/2025 Modified 01/10/2025 Description Requests is a HTTP library. Prior to 2.32.0, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. This vulnerability is fixed in 2.32.0. An incorrect control flow implementation vulnerability was found in Requests. If the first request in a session is made with verify=False, all subsequent requests to the same host will continue to ignore cert verification.

Debian: CVE-2024-35997: linux -- security update Severity 5 CVSS (AV:L/AC:L/Au:S/C:N/I:N/A:C) Published 05/20/2024 Created 06/28/2024 Added 06/27/2024 Modified 01/28/2025 Description In the Linux kernel, the following vulnerability has been resolved: HID: i2c-hid: remove I2C_HID_READ_PENDING flag to prevent lock-up The flag I2C_HID_READ_PENDING is used to serialize I2C operations. However, this is not necessary, because I2C core already has its own locking for that. More importantly, this flag can cause a lock-up: if the flag is set in i2c_hid_xfer() and an interrupt happens, the interrupt handler (i2c_hid_irq) will check this flag and return immediately without doing anything, then the interrupt handler will be invoked again in an infinite loop. Since interrupt handler is an RT task, it takes over the CPU and the flag-clearing task never gets scheduled, thus we have a lock-up. Delete this unnecessary flag.

Huawei EulerOS: CVE-2024-35969: kernel security update Severity 4 CVSS (AV:L/AC:M/Au:N/C:P/I:P/A:P) Published 05/20/2024 Created 10/09/2024 Added 10/08/2024 Modified 10/08/2024 Description In the Linux kernel, the following vulnerability has been resolved: ipv6: fix race condition between ipv6_get_ifaddr and ipv6_del_addr Although ipv6_get_ifaddr walks inet6_addr_lst under the RCU lock, it still means hlist_for_each_entry_rcu can return an item that got removed from the list. The memory itself of such item is not freed thanks to RCU but nothing guarantees the actual content of the memory is sane. In particular, the reference count can be zero. This can happen if ipv6_del_addr is called in parallel. ipv6_del_addr removes the entry from inet6_addr_lst (hlist_del_init_rcu(&ifp->addr_lst)) and drops all references (__in6_ifa_put(ifp) + in6_ifa_put(ifp)). With bad enough timing, this can happen: 1. In ipv6_get_ifaddr, hlist_for_each_entry_rcu returns an entry. 2. Then, the whole ipv6_del_addr is executed for the given entry. The reference count drops to zero and kfree_rcu is scheduled. 3. ipv6_get_ifaddr continues and tries to increments the reference count (in6_ifa_hold). 4. The rcu is unlocked and the entry is freed. 5. The freed entry is returned. Prevent increasing of the reference count in such case. The name in6_ifa_hold_safe is chosen to mimic the existing fib6_info_hold_safe. [ 41.506330] refcount_t: addition on 0; use-after-free.
